[PATCH v2 00/13] rtw88: mac80211 driver for Realtek 802.11ac wireless network chips
From: Yan-Hsuan Chuang This is a new mac80211 driver for Realtek 802.11ac wireless network chips. rtw88 supports 8822BE and 8822CE chips, and will be able to support multi-vif combinations in run-time. For now, only PCI bus is supported, but rtw88 was originally designed to optionally support three buses includes USB & SDIO. USB & SDIO modules will soon be supported by rtw88, with configurable core module to fit with different bus modules in the same time. For example, if we choose 8822BE and 8822CU, only PCI & USB modules will be selected, built, loaded into kernel. This is one of the major difference from rtlwifi, which can only support specific combinations. Another difference from rtlwifi is that rtw88 is designed to support the latest Realtek 802.11ac wireless network chips like 8822B and 8822C series. Compared to the earlier chips supported by rtlwifi like the 802.11n 8192EE chipset or 802.11ac 8821AE/8812AE chips, newer ICs have different MAC & PHY settings, such as new multi-port feature for the MAC layer design and Jaguar2/Jaguar3 PHY layer IPs. Multi-Port feature is also supported under rtw88's software architecture. rtlwifi can only support one vif in the same time, most because of the hardware limitations for early chips, hence the original design of it also restricts the usage of multi-vif support, so latest chipset seems not take advantages from its new MAC engine. However, rtw88 can run multiple vifs concurrently by holding them on hardware ports provided by MAC engine, hence can easily start different roles on a single device. Based on the reasons mentioned before, we implemented rtw88. It had many authors, they are listed here alphabetically: Ping-Ke Shih Tzu-En Huang Yan-Hsuan Chuang v2 - add comment for watch dog Yan-Hsuan Chuang (13): rtw88: main files rtw88: core files rtw88: hci files rtw88: trx files rtw88: mac files rtw88: fw and efuse files rtw88: phy files rtw88: debug files rtw88: chip files rtw88: 8822B init table rtw88: 8822C init table rtw88: Kconfig & Makefile rtw88: add support for Realtek 802.11ac wireless chips MAINTAINERS| 8 + drivers/net/wireless/realtek/Kconfig | 1 + drivers/net/wireless/realtek/Makefile | 1 + drivers/net/wireless/realtek/rtw88/Kconfig |55 + drivers/net/wireless/realtek/rtw88/Makefile|19 + drivers/net/wireless/realtek/rtw88/debug.c | 631 + drivers/net/wireless/realtek/rtw88/debug.h |35 + drivers/net/wireless/realtek/rtw88/efuse.c | 150 + drivers/net/wireless/realtek/rtw88/efuse.h |53 + drivers/net/wireless/realtek/rtw88/fw.c| 611 + drivers/net/wireless/realtek/rtw88/fw.h| 213 + drivers/net/wireless/realtek/rtw88/hci.h | 211 + drivers/net/wireless/realtek/rtw88/mac.c | 1010 + drivers/net/wireless/realtek/rtw88/mac.h |35 + drivers/net/wireless/realtek/rtw88/mac80211.c | 480 + drivers/net/wireless/realtek/rtw88/main.c | 1190 ++ drivers/net/wireless/realtek/rtw88/main.h | 1119 + drivers/net/wireless/realtek/rtw88/pci.c | 1208 ++ drivers/net/wireless/realtek/rtw88/pci.h | 229 + drivers/net/wireless/realtek/rtw88/phy.c | 1670 ++ drivers/net/wireless/realtek/rtw88/phy.h | 125 + drivers/net/wireless/realtek/rtw88/ps.c| 165 + drivers/net/wireless/realtek/rtw88/ps.h|20 + drivers/net/wireless/realtek/rtw88/reg.h | 411 + drivers/net/wireless/realtek/rtw88/regd.c | 391 + drivers/net/wireless/realtek/rtw88/regd.h |67 + drivers/net/wireless/realtek/rtw88/rtw8822b.c | 1590 ++ drivers/net/wireless/realtek/rtw88/rtw8822b.h | 155 + .../net/wireless/realtek/rtw88/rtw8822b_table.c| 20783 +++ .../net/wireless/realtek/rtw88/rtw8822b_table.h|18 + drivers/net/wireless/realtek/rtw88/rtw8822c.c | 1169 ++ drivers/net/wireless/realtek/rtw88/rtw8822c.h | 171 + .../net/wireless/realtek/rtw88/rtw8822c_table.c| 4150 .../net/wireless/realtek/rtw88/rtw8822c_table.h|16 + drivers/net/wireless/realtek/rtw88/rx.c| 151 + drivers/net/wireless/realtek/rtw88/rx.h|41 + drivers/net/wireless/realtek/rtw88/sec.c | 120 + drivers/net/wireless/realtek/rtw88/sec.h |39 + drivers/net/wireless/realtek/rtw88/tx.c| 273 + drivers/net/wireless/realtek/rtw88/tx.h|81 + 40 files changed, 38865 insertions(+) create mode 100644 drivers/net/wireless/realtek/rtw88/Kconfig create mode 100644 drivers/net/wireless/realtek/rtw88/Makefile create mode 100644 drivers/net/wireless/realtek/rtw88/debug.c create mode 100644 drivers/net/wireless/realtek/rtw88/debug.h create mode 100644 drivers/net/wireless/realtek/rtw88/efuse.c create

[PATCH 00/13] rtw88: mac80211 driver for Realtek 802.11ac wireless network chips
From: Yan-Hsuan Chuang As rtw88 has been discussed for two months, this is the first PATCH series for rtw88. The only change with respect to RFC v5 is the debug system. We move debug log with levels such as rtw_[info/warn/err]() out of the internal debug flag but leave rtw_dbg() remained in the flag. As suggested, they should not be turned off based on the debug config flag. And since they are moved out of the debug flag, the function call is unnecessary, we can just use macros for them. The other description about rtw88 are remained below, as the RFC series. This is a new mac80211 driver for Realtek 802.11ac wireless network chips. rtw88 supports 8822BE and 8822CE chips, and will be able to support multi-vif combinations in run-time. For now, only PCI bus is supported, but rtw88 was originally designed to optionally support three buses includes USB & SDIO. USB & SDIO modules will soon be supported by rtw88, with configurable core module to fit with different bus modules in the same time. For example, if we choose 8822BE and 8822CU, only PCI & USB modules will be selected, built, loaded into kernel. This is one of the major difference from rtlwifi, which can only support specific combinations. Another difference from rtlwifi is that rtw88 is designed to support the latest Realtek 802.11ac wireless network chips like 8822B and 8822C series. Compared to the earlier chips supported by rtlwifi like the 802.11n 8192EE chipset or 802.11ac 8821AE/8812AE chips, newer ICs have different MAC & PHY settings, such as new multi-port feature for the MAC layer design and Jaguar2/Jaguar3 PHY layer IPs. Multi-Port feature is also supported under rtw88's software architecture. rtlwifi can only support one vif in the same time, most because of the hardware limitations for early chips, hence the original design of it also restricts the usage of multi-vif support, so latest chipset seems not take advantages from its new MAC engine. However, rtw88 can run multiple vifs concurrently by holding them on hardware ports provided by MAC engine, hence can easily start different roles on a single device. Based on the reasons mentioned before, we implemented rtw88. It had many authors, they are listed here alphabetically: Ping-Ke Shih Tzu-En Huang Yan-Hsuan Chuang Yan-Hsuan Chuang (13): rtw88: main files rtw88: core files rtw88: hci files rtw88: trx files rtw88: mac files rtw88: fw and efuse files rtw88: phy files rtw88: debug files rtw88: chip files rtw88: 8822B init table rtw88: 8822C init table rtw88: Kconfig & Makefile rtw88: add support for Realtek 802.11ac wireless chips MAINTAINERS| 8 + drivers/net/wireless/realtek/Kconfig | 1 + drivers/net/wireless/realtek/Makefile | 1 + drivers/net/wireless/realtek/rtw88/Kconfig |55 + drivers/net/wireless/realtek/rtw88/Makefile|19 + drivers/net/wireless/realtek/rtw88/debug.c | 631 + drivers/net/wireless/realtek/rtw88/debug.h |35 + drivers/net/wireless/realtek/rtw88/efuse.c | 150 + drivers/net/wireless/realtek/rtw88/efuse.h |53 + drivers/net/wireless/realtek/rtw88/fw.c| 611 + drivers/net/wireless/realtek/rtw88/fw.h| 213 + drivers/net/wireless/realtek/rtw88/hci.h | 211 + drivers/net/wireless/realtek/rtw88/mac.c | 1010 + drivers/net/wireless/realtek/rtw88/mac.h |35 + drivers/net/wireless/realtek/rtw88/mac80211.c | 480 + drivers/net/wireless/realtek/rtw88/main.c | 1187 ++ drivers/net/wireless/realtek/rtw88/main.h | 1119 + drivers/net/wireless/realtek/rtw88/pci.c | 1208 ++ drivers/net/wireless/realtek/rtw88/pci.h | 229 + drivers/net/wireless/realtek/rtw88/phy.c | 1670 ++ drivers/net/wireless/realtek/rtw88/phy.h | 125 + drivers/net/wireless/realtek/rtw88/ps.c| 165 + drivers/net/wireless/realtek/rtw88/ps.h|20 + drivers/net/wireless/realtek/rtw88/reg.h | 411 + drivers/net/wireless/realtek/rtw88/regd.c | 391 + drivers/net/wireless/realtek/rtw88/regd.h |67 + drivers/net/wireless/realtek/rtw88/rtw8822b.c | 1590 ++ drivers/net/wireless/realtek/rtw88/rtw8822b.h | 155 + .../net/wireless/realtek/rtw88/rtw8822b_table.c| 20783 +++ .../net/wireless/realtek/rtw88/rtw8822b_table.h|18 + drivers/net/wireless/realtek/rtw88/rtw8822c.c | 1169 ++ drivers/net/wireless/realtek/rtw88/rtw8822c.h | 171 + .../net/wireless/realtek/rtw88/rtw8822c_table.c| 4150 .../net/wireless/realtek/rtw88/rtw8822c_table.h|16 + drivers/net/wireless/realtek/rtw88/rx.c| 151 + drivers/net/wireless/realtek/rtw88/rx.h|41 + drivers/net/wireless/realtek/rtw88/sec.c | 120 + drivers/net/wireless/realtek/rtw88/sec.h

cfg80211_sta_opmode_change_notify needs a gfp_t flag to hint the nl80211
stack when allocating new skb, but it is called under tasklet context
here with GFP_KERNEL and kernel will yield a warning about it.

[RFC v5 00/13] rtw88: mac80211 driver for Realtek 802.11ac wireless network chips
From: Yan-Hsuan Chuang This is a new mac80211 driver for Realtek 802.11ac wireless network chips. rtw88 supports 8822BE and 8822CE chips, and will be able to support multi-vif combinations in run-time. For now, only PCI bus is supported, but rtw88 was originally designed to optionally support three buses includes USB & SDIO. USB & SDIO modules will soon be supported by rtw88, with configurable core module to fit with different bus modules in the same time. For example, if we choose 8822BE and 8822CU, only PCI & USB modules will be selected, built, loaded into kernel. This is one of the major difference from rtlwifi, which can only support specific combinations. Another difference from rtlwifi is that rtw88 is designed to support the latest Realtek 802.11ac wireless network chips like 8822B and 8822C series. Compared to the earlier chips supported by rtlwifi like the 802.11n 8192EE chipset or 802.11ac 8821AE/8812AE chips, newer ICs have different MAC & PHY settings, such as new multi-port feature for the MAC layer design and Jaguar2/Jaguar3 PHY layer IPs. Multi-Port feature is also supported under rtw88's software architecture. rtlwifi can only support one vif in the same time, most because of the hardware limitations for early chips, hence the original design of it also restricts the usage of multi-vif support, so latest chipset seems not take advantages from its new MAC engine. However, rtw88 can run multiple vifs concurrently by holding them on hardware ports provided by MAC engine, hence can easily start different roles on a single device. Based on the reasons mentioned before, we implemented rtw88. It had many authors, they are listed here alphabetically: Ping-Ke Shih Tzu-En Huang Yan-Hsuan Chuang v5 - make all strings terminated with a new line - use request_firmware_nowait to not block if the driver is built-in in the kernel - code cleanup for h2c functions - simplify vif and sta iterators - apply correct regulatory settings - error check for kmalloc and skb_alloc - use check_hw_ready to achieve hw pollings v4 - remove vis_list and sta_list, use mac80211 iterator - use kernel helpers such as bitmap, bcd2bin, lockdep - move debugfs into wiphy->debugfsdir - use spin_lock in interrupt handler - remove unnecessary depends on lines in Kconfig - make port config constant - avoid watchdog timer spreading - return -EOPNOTSUPP for PMF key error message suppression - do not replace regd in wiphy for now - use host- fix- endian transfer in linux/bitfield.h to replace/get bits to/from card v3 - missing rcu list traverse for vif_list v2 - rename from rtwlan to rtw88 - remove lots of magic numbers - add pci null entry for auto load on boot - add rtwdev->mutex to protect against mac80211 callbacks - add rcu lock protection for vif_list and sta_list - refine bits & endian macros to use helper functions provided by kernel instead of create new ones - ieee80211_free_txskb for tx path dropped packets - not register iface_combination since now only one vif is allowed - some fixes suggested by Stanislaw Yan-Hsuan Chuang (13): rtw88: main files rtw88: core files rtw88: hci files rtw88: trx files rtw88: mac files rtw88: fw and efuse files rtw88: phy files rtw88: debug files rtw88: chip files rtw88: 8822B init table rtw88: 8822C init table rtw88: Kconfig & Makefile rtw88: add support for Realtek 802.11ac wireless chips MAINTAINERS| 8 + drivers/net/wireless/realtek/Kconfig | 1 + drivers/net/wireless/realtek/Makefile | 1 + drivers/net/wireless/realtek/rtw88/Kconfig |55 + drivers/net/wireless/realtek/rtw88/Makefile|19 + drivers/net/wireless/realtek/rtw88/debug.c | 652 + drivers/net/wireless/realtek/rtw88/debug.h |43 + drivers/net/wireless/realtek/rtw88/efuse.c | 150 + drivers/net/wireless/realtek/rtw88/efuse.h |53 + drivers/net/wireless/realtek/rtw88/fw.c| 611 + drivers/net/wireless/realtek/rtw88/fw.h| 213 + drivers/net/wireless/realtek/rtw88/hci.h | 211 + drivers/net/wireless/realtek/rtw88/mac.c | 1010 + drivers/net/wireless/realtek/rtw88/mac.h |35 + drivers/net/wireless/realtek/rtw88/mac80211.c | 480 + drivers/net/wireless/realtek/rtw88/main.c | 1187 ++ drivers/net/wireless/realtek/rtw88/main.h | 1119 + drivers/net/wireless/realtek/rtw88/pci.c | 1208 ++ drivers/net/wireless/realtek/rtw88/pci.h | 229 + drivers/net/wireless/realtek/rtw88/phy.c | 1670 ++ drivers/net/wireless/realtek/rtw88/phy.h | 125 + drivers/net/wireless/realtek/rtw88/ps.c| 165 + drivers/net/wireless/realtek/rtw88/ps.h|20 + drivers/net/wireless/realtek/rtw88/reg.h | 411 + drivers/net/wireless/realtek/rtw88/regd.c |

[PATCH] mac80211: fix GFP_KERNEL under tasklet context
From: Yan-Hsuan Chuang
cfg80211_sta_opmode_change_notify needs a gfp_t flag to hint the nl80211
stack when allocating new skb, but it is called under tasklet context
here with GFP_KERNEL and kernel will yield a warning about it.

modification.")

[RFC v4 00/13] rtw88: mac80211 driver for Realtek 802.11ac wireless network chips
From: Yan-Hsuan Chuang This is a new mac80211 driver for Realtek 802.11ac wireless network chips. rtw88 supports 8822BE and 8822CE chips, and will be able to support multi-vif combinations in run-time. For now, only PCI bus is supported, but rtw88 was originally designed to optionally support three buses includes USB & SDIO. USB & SDIO modules will soon be supported by rtw88, with configurable core module to fit with different bus modules in the same time. For example, if we choose 8822BE and 8822CU, only PCI & USB modules will be selected, built, loaded into kernel. This is one of the major difference from rtlwifi, which can only support specific combinations. Another difference from rtlwifi is that rtw88 is designed to support the latest Realtek 802.11ac wireless network chips like 8822B and 8822C series. Compared to the earlier chips supported by rtlwifi like the 802.11n 8192EE chipset or 802.11ac 8821AE/8812AE chips, newer ICs have different MAC & PHY settings, such as new multi-port feature for the MAC layer design and Jaguar2/Jaguar3 PHY layer IPs. Multi-Port feature is also supported under rtw88's software architecture. rtlwifi can only support one vif in the same time, most because of the hardware limitations for early chips, hence the original design of it also restricts the usage of multi-vif support, so latest chipset seems not take advantages from its new MAC engine. However, rtw88 can run multiple vifs concurrently by holding them on hardware ports provided by MAC engine, hence can easily start different roles on a single device. Based on the reasons mentioned before, we implemented rtw88. It had many authors, they are listed here alphabetically: Ping-Ke Shih Tzu-En Huang Yan-Hsuan Chuang v4 - remove vis_list and sta_list, use mac80211 iterator - use kernel helpers such as bitmap, bcd2bin, lockdep - move debugfs into wiphy->debugfsdir - use spin_lock in interrupt handler - remove unnecessary depends on lines in Kconfig - make port config constant - avoid watchdog timer spreading - return -EOPNOTSUPP for PMF key error message suppression - do not replace regd in wiphy for now - use host- fix- endian transfer in linux/bitfield.h to replace/get bits to/from card v3 - missing rcu list traverse for vif_list v2 - rename from rtwlan to rtw88 - remove lots of magic numbers - add pci null entry for auto load on boot - add rtwdev->mutex to protect against mac80211 callbacks - add rcu lock protection for vif_list and sta_list - refine bits & endian macros to use helper functions provided by kernel instead of create new ones - ieee80211_free_txskb for tx path dropped packets - not register iface_combination since now only one vif is allowed - some fixes suggested by Stanislaw Yan-Hsuan Chuang (13): rtw88: main files rtw88: core files rtw88: hci files rtw88: trx files rtw88: mac files rtw88: fw and efuse files rtw88: phy files rtw88: debug files rtw88: chip files rtw88: 8822B init table rtw88: 8822C init table rtw88: Kconfig & Makefile rtw88: add support for Realtek 802.11ac wireless chips MAINTAINERS| 8 + drivers/net/wireless/realtek/Kconfig | 1 + drivers/net/wireless/realtek/Makefile | 1 + drivers/net/wireless/realtek/rtw88/Kconfig |55 + drivers/net/wireless/realtek/rtw88/Makefile|19 + drivers/net/wireless/realtek/rtw88/debug.c | 652 + drivers/net/wireless/realtek/rtw88/debug.h |43 + drivers/net/wireless/realtek/rtw88/efuse.c | 150 + drivers/net/wireless/realtek/rtw88/efuse.h |53 + drivers/net/wireless/realtek/rtw88/fw.c| 655 + drivers/net/wireless/realtek/rtw88/fw.h| 182 + drivers/net/wireless/realtek/rtw88/hci.h | 211 + drivers/net/wireless/realtek/rtw88/mac.c | 1045 + drivers/net/wireless/realtek/rtw88/mac.h |35 + drivers/net/wireless/realtek/rtw88/mac80211.c | 478 + drivers/net/wireless/realtek/rtw88/main.c | 1168 ++ drivers/net/wireless/realtek/rtw88/main.h | 1092 + drivers/net/wireless/realtek/rtw88/pci.c | 1208 ++ drivers/net/wireless/realtek/rtw88/pci.h | 229 + drivers/net/wireless/realtek/rtw88/phy.c | 1679 ++ drivers/net/wireless/realtek/rtw88/phy.h | 125 + drivers/net/wireless/realtek/rtw88/ps.c| 168 + drivers/net/wireless/realtek/rtw88/ps.h|20 + drivers/net/wireless/realtek/rtw88/reg.h | 404 + drivers/net/wireless/realtek/rtw88/regd.c | 328 + drivers/net/wireless/realtek/rtw88/regd.h |40 + drivers/net/wireless/realtek/rtw88/rtw8822b.c | 1588 ++ drivers/net/wireless/realtek/rtw88/rtw8822b.h | 155 + .../net/wireless/realtek/rtw88/rtw8822b_table.c| 20783 +++ .../net/wireless/realtek/rtw88/rtw8822b_table.h|18

[RFC v3 00/12] rtw88: mac80211 driver for Realtek 802.11ac wireless network chips
From: Yan-Hsuan Chuang This is a new mac80211 driver for Realtek 802.11ac wireless network chips. rtwlan supports 8822BE and 8822CE chips, and will be able to support multi-vif combinations in run-time. For now, only PCI bus is supported, but rtwlan was originally designed to optionally support three buses includes USB & SDIO. USB & SDIO modules will soon be supported by rtwlan, with configurable core module to fit with different bus modules in the same time. For example, if we choose 8822BE and 8822CU, only PCI & USB modules will be selected, built, loaded into kernel. This is one of the major difference from rtlwifi, which can only support specific combinations. Another difference from rtlwifi is that rtwlan is designed to support the latest Realtek 802.11ac wireless network chips like 8822B and 8822C series. Compared to the earlier chips supported by rtlwifi like the 802.11n 8192EE chipset or 802.11ac 8821AE/8812AE chips, newer ICs have different MAC & PHY settings, such as new multi-port feature for the MAC layer design and Jaguar2/Jaguar3 PHY layer IPs. Multi-Port feature is also supported under rtwlan's software architecture. rtlwifi can only support one vif in the same time, most because of the hardware limitations for early chips, hence the original design of it also restricts the usage of multi-vif support, so latest chipset seems not take advantages from its new MAC engine. However, rtwlan can run multiple vifs concurrently by holding them on hardware ports provided by MAC engine, hence can easily start different roles on a single device. Based on the reasons mentioned before, we implemented rtwlan. It had many authors, they are listed here alphabetically: Ping-Ke Shih Tzu-En Huang Yan-Hsuan Chuang v3 - missing rcu list traverse for vif_list v2 - rename from rtwlan to rtw88 - remove lots of magic numbers - add pci null entry for auto load on boot - add rtwdev->mutex to protect against mac80211 callbacks - add rcu lock protection for vif_list and sta_list - refine bits & endian macros to use helper functions provided by kernel instead of create new ones - ieee80211_free_txskb for tx path dropped packets - not register iface_combination since now only one vif is allowed - some fixes suggested by Stanislaw Yan-Hsuan Chuang (12): rtw88: main files rtw88: core files rtw88: hci files rtw88: trx files rtw88: mac files rtw88: fw and efuse files rtw88: phy files rtw88: debug files rtw88: chip files rtw88: 8822B init table rtw88: 8822C init table rtw88: Kconfig & Makefile drivers/net/wireless/realtek/Kconfig | 1 + drivers/net/wireless/realtek/Makefile | 1 + drivers/net/wireless/realtek/rtw88/Kconfig |57 + drivers/net/wireless/realtek/rtw88/Makefile|19 + drivers/net/wireless/realtek/rtw88/debug.c | 652 + drivers/net/wireless/realtek/rtw88/debug.h |45 + drivers/net/wireless/realtek/rtw88/efuse.c | 150 + drivers/net/wireless/realtek/rtw88/efuse.h |53 + drivers/net/wireless/realtek/rtw88/fw.c| 638 + drivers/net/wireless/realtek/rtw88/fw.h| 182 + drivers/net/wireless/realtek/rtw88/hci.h | 212 + drivers/net/wireless/realtek/rtw88/mac.c | 1045 + drivers/net/wireless/realtek/rtw88/mac.h |35 + drivers/net/wireless/realtek/rtw88/mac80211.c | 482 + drivers/net/wireless/realtek/rtw88/main.c | 1133 + drivers/net/wireless/realtek/rtw88/main.h | 1200 ++ drivers/net/wireless/realtek/rtw88/pci.c | 1220 ++ drivers/net/wireless/realtek/rtw88/pci.h | 228 + drivers/net/wireless/realtek/rtw88/phy.c | 1675 ++ drivers/net/wireless/realtek/rtw88/phy.h | 125 + drivers/net/wireless/realtek/rtw88/ps.c| 198 + drivers/net/wireless/realtek/rtw88/ps.h|21 + drivers/net/wireless/realtek/rtw88/reg.h | 404 + drivers/net/wireless/realtek/rtw88/regd.c | 462 + drivers/net/wireless/realtek/rtw88/regd.h |40 + drivers/net/wireless/realtek/rtw88/rtw8822b.c | 1593 ++ drivers/net/wireless/realtek/rtw88/rtw8822b.h | 271 + .../net/wireless/realtek/rtw88/rtw8822b_table.c| 20783 +++ .../net/wireless/realtek/rtw88/rtw8822b_table.h|18 + drivers/net/wireless/realtek/rtw88/rtw8822c.c | 1170 ++ drivers/net/wireless/realtek/rtw88/rtw8822c.h | 416 + .../net/wireless/realtek/rtw88/rtw8822c_table.c| 4150 .../net/wireless/realtek/rtw88/rtw8822c_table.h|16 + drivers/net/wireless/realtek/rtw88/rx.c| 144 + drivers/net/wireless/realtek/rtw88/rx.h|30 + drivers/net/wireless/realtek/rtw88/sec.c | 135 + drivers/net/wireless/realtek/rtw88/sec.h |40 + drivers/net/wireless/realtek/rtw88/tx.c| 271 + drivers/net/wireless/realtek/rtw88/tx.h

[RFC v2 00/12] rtw88: mac80211 driver for Realtek 802.11ac wireless network chips
From: Yan-Hsuan Chuang This is a new mac80211 driver for Realtek 802.11ac wireless network chips. rtwlan supports 8822BE and 8822CE chips, and will be able to support multi-vif combinations in run-time. For now, only PCI bus is supported, but rtwlan was originally designed to optionally support three buses includes USB & SDIO. USB & SDIO modules will soon be supported by rtwlan, with configurable core module to fit with different bus modules in the same time. For example, if we choose 8822BE and 8822CU, only PCI & USB modules will be selected, built, loaded into kernel. This is one of the major difference from rtlwifi, which can only support specific combinations. Another difference from rtlwifi is that rtwlan is designed to support the latest Realtek 802.11ac wireless network chips like 8822B and 8822C series. Compared to the earlier chips supported by rtlwifi like the 802.11n 8192EE chipset or 802.11ac 8821AE/8812AE chips, newer ICs have different MAC & PHY settings, such as new multi-port feature for the MAC layer design and Jaguar2/Jaguar3 PHY layer IPs. Multi-Port feature is also supported under rtwlan's software architecture. rtlwifi can only support one vif in the same time, most because of the hardware limitations for early chips, hence the original design of it also restricts the usage of multi-vif support, so latest chipset seems not take advantages from its new MAC engine. However, rtwlan can run multiple vifs concurrently by holding them on hardware ports provided by MAC engine, hence can easily start different roles on a single device. Based on the reasons mentioned before, we implemented rtwlan. It had many authors, they are listed here alphabetically: Ping-Ke Shih Tzu-En Huang Yan-Hsuan Chuang v2 - rename from rtwlan to rtw88 - remove lots of magic numbers - add pci null entry for auto load on boot - add rtwdev->mutex to protect against mac80211 callbacks - add rcu lock protection for vif_list and sta_list - refine bits & endian macros to use helper functions provided by kernel instead of create new ones - ieee80211_free_txskb for tx path dropped packets - not register iface_combination since now only one vif is allowed - some fixes suggested by Stanislaw Yan-Hsuan Chuang (12): rtw88: main files rtw88: core files rtw88: hci files rtw88: trx files rtw88: mac files rtw88: fw and efuse files rtw88: phy files rtw88: debug files rtw88: chip files rtw88: 8822B init table rtw88: 8822C init table rtw88: Kconfig & Makefile drivers/net/wireless/realtek/Kconfig | 1 + drivers/net/wireless/realtek/Makefile | 1 + drivers/net/wireless/realtek/rtw88/Kconfig |57 + drivers/net/wireless/realtek/rtw88/Makefile|19 + drivers/net/wireless/realtek/rtw88/debug.c | 652 + drivers/net/wireless/realtek/rtw88/debug.h |45 + drivers/net/wireless/realtek/rtw88/efuse.c | 150 + drivers/net/wireless/realtek/rtw88/efuse.h |53 + drivers/net/wireless/realtek/rtw88/fw.c| 638 + drivers/net/wireless/realtek/rtw88/fw.h| 182 + drivers/net/wireless/realtek/rtw88/hci.h | 212 + drivers/net/wireless/realtek/rtw88/mac.c | 1045 + drivers/net/wireless/realtek/rtw88/mac.h |35 + drivers/net/wireless/realtek/rtw88/mac80211.c | 482 + drivers/net/wireless/realtek/rtw88/main.c | 1133 + drivers/net/wireless/realtek/rtw88/main.h | 1200 ++ drivers/net/wireless/realtek/rtw88/pci.c | 1220 ++ drivers/net/wireless/realtek/rtw88/pci.h | 228 + drivers/net/wireless/realtek/rtw88/phy.c | 1675 ++ drivers/net/wireless/realtek/rtw88/phy.h | 125 + drivers/net/wireless/realtek/rtw88/ps.c| 198 + drivers/net/wireless/realtek/rtw88/ps.h|21 + drivers/net/wireless/realtek/rtw88/reg.h | 404 + drivers/net/wireless/realtek/rtw88/regd.c | 462 + drivers/net/wireless/realtek/rtw88/regd.h |40 + drivers/net/wireless/realtek/rtw88/rtw8822b.c | 1593 ++ drivers/net/wireless/realtek/rtw88/rtw8822b.h | 271 + .../net/wireless/realtek/rtw88/rtw8822b_table.c| 20783 +++ .../net/wireless/realtek/rtw88/rtw8822b_table.h|18 + drivers/net/wireless/realtek/rtw88/rtw8822c.c | 1170 ++ drivers/net/wireless/realtek/rtw88/rtw8822c.h | 416 + .../net/wireless/realtek/rtw88/rtw8822c_table.c| 4150 .../net/wireless/realtek/rtw88/rtw8822c_table.h|16 + drivers/net/wireless/realtek/rtw88/rx.c| 144 + drivers/net/wireless/realtek/rtw88/rx.h|30 + drivers/net/wireless/realtek/rtw88/sec.c | 135 + drivers/net/wireless/realtek/rtw88/sec.h |40 + drivers/net/wireless/realtek/rtw88/tx.c| 271 + drivers/net/wireless/realtek/rtw88/tx.h|81 + 39 files changed, 39396

[RFC 00/12] rtwlan: mac80211 driver for Realtek 802.11ac wireless network chips
From: Yan-Hsuan Chuang This is a new mac80211 driver for Realtek 802.11ac wireless network chips. rtwlan supports 8822BE and 8822CE chips, and will be able to support multi-vif combinations in run-time. For now, only PCI bus is supported, but rtwlan was originally designed to optionally support three buses includes USB & SDIO. USB & SDIO modules will soon be supported by rtwlan, with configurable core module to fit with different bus modules in the same time. For example, if we choose 8822BE and 8822CU, only PCI & USB modules will be selected, built, loaded into kernel. This is one of the major difference from rtlwifi, which can only support specific combinations. Another difference from rtlwifi is that rtwlan is designed to support the latest Realtek 802.11ac wireless network chips like 8822B and 8822C series. Compared to the earlier chips supported by rtlwifi like the 802.11n 8192EE chipset or 802.11ac 8821AE/8812AE chips, newer ICs have different MAC & PHY settings, such as new multi-port feature for the MAC layer design and Jaguar2/Jaguar3 PHY layer IPs. Multi-Port feature is also supported under rtwlan's software architecture. rtlwifi can only support one vif in the same time, most because of the hardware limitations for early chips, hence the original design of it also restricts the usage of multi-vif support, so latest chipset seems not take advantages from its new MAC engine. However, rtwlan can run multiple vifs concurrently by holding them on hardware ports provided by MAC engine, so we can easily start different roles on a single device. Based on the reasons mentioned before, we implemented rtwlan. It had many authors, they are listed here alphabetically: Ping-Ke Shih Tzu-En Huang Yan-Hsuan Chuang Signed-off-by: Yan-Hsuan Chuang Signed-off-by: Ping-Ke Shih Yan-Hsuan Chuang (12): rtwlan: main files rtwlan: core files rtwlan: hci files rtwlan: trx files rtwlan: mac files rtwlan: fw and efuse files rtwlan: phy files rtwlan: debug files rtwlan: chip files rtwlan: 8822B init table rtwlan: 8822C init table rtwlan: Kconfig & Makefile drivers/net/wireless/realtek/Kconfig | 1 + drivers/net/wireless/realtek/Makefile | 1 + drivers/net/wireless/realtek/rtwlan/Kconfig|55 + drivers/net/wireless/realtek/rtwlan/Makefile |21 + drivers/net/wireless/realtek/rtwlan/debug.c| 653 + drivers/net/wireless/realtek/rtwlan/debug.h|45 + drivers/net/wireless/realtek/rtwlan/efuse.c| 153 + drivers/net/wireless/realtek/rtwlan/efuse.h|53 + drivers/net/wireless/realtek/rtwlan/fw.c | 640 + drivers/net/wireless/realtek/rtwlan/fw.h | 182 + drivers/net/wireless/realtek/rtwlan/hci.h | 212 + drivers/net/wireless/realtek/rtwlan/mac.c | 1063 + drivers/net/wireless/realtek/rtwlan/mac.h |35 + drivers/net/wireless/realtek/rtwlan/mac80211.c | 447 + drivers/net/wireless/realtek/rtwlan/main.c | 1164 ++ drivers/net/wireless/realtek/rtwlan/main.h | 1188 ++ drivers/net/wireless/realtek/rtwlan/pci.c | 1217 ++ drivers/net/wireless/realtek/rtwlan/pci.h | 227 + drivers/net/wireless/realtek/rtwlan/phy.c | 1671 ++ drivers/net/wireless/realtek/rtwlan/phy.h | 125 + drivers/net/wireless/realtek/rtwlan/ps.c | 193 + drivers/net/wireless/realtek/rtwlan/ps.h |21 + drivers/net/wireless/realtek/rtwlan/reg.h | 399 + drivers/net/wireless/realtek/rtwlan/regd.c | 462 + drivers/net/wireless/realtek/rtwlan/regd.h |40 + drivers/net/wireless/realtek/rtwlan/rtw8822b.c | 1572 ++ drivers/net/wireless/realtek/rtwlan/rtw8822b.h | 270 + .../net/wireless/realtek/rtwlan/rtw8822b_table.c | 20783 +++ .../net/wireless/realtek/rtwlan/rtw8822b_table.h |18 + drivers/net/wireless/realtek/rtwlan/rtw8822c.c | 1164 ++ drivers/net/wireless/realtek/rtwlan/rtw8822c.h | 403 + .../net/wireless/realtek/rtwlan/rtw8822c_table.c | 4150 .../net/wireless/realtek/rtwlan/rtw8822c_table.h |16 + drivers/net/wireless/realtek/rtwlan/rx.c | 138 + drivers/net/wireless/realtek/rtwlan/rx.h |30 + drivers/net/wireless/realtek/rtwlan/sec.c | 135 + drivers/net/wireless/realtek/rtwlan/sec.h |40 + drivers/net/wireless/realtek/rtwlan/tx.c | 271 + drivers/net/wireless/realtek/rtwlan/tx.h |81 + 39 files changed, 39339 insertions(+) create mode 100644 drivers/net/wireless/realtek/rtwlan/Kconfig create mode 100644 drivers/net/wireless/realtek/rtwlan/Makefile create mode 100644 drivers/net/wireless/realtek/rtwlan/debug.c create mode 100644 drivers/net/wireless/realtek/rtwlan/debug.h create mode 100644 drivers/net/wireless/realtek/rtwlan/efuse.c create mode 100644 drivers/net/wireless/realtek/rtwlan/efuse.h create mode
