But yes, would love to work on AR9271! What is the rtl8188ee? Maybe I'd recognize the brand and model. I have Hiro H50191, which uses rsu driver. That last URL looks like something related to Illumos and OpenIndiana. My Atheros AR9271 is (quasi-)USB, an inseparable part of the motherboard in contrast to the Hiro H50191 which is a USB-stick wireless adapter. It has sometimes worked on NetBSD, but more often would fail to load firmware. On latest NetBSD-current, it stops the kernel from booting unless I disable it or comment out in kernel config. GENERIC kernel reboots immediately without showing any messages. OpenBSD also has AR9271 driver and Realtek re. I have NetBSD installations but no OpenBSD. I would like, at first, if possible, when I have a driver to build, to build the module rather than the whole kernel every time. I am familiar with C and C++ but think I need to brush up. Any online leads/references?

Re: Adding wifi source code
Thomas, I was planning on also porting over the Atheros AR9271 driver from NetBSD (athn(4) /usr/src/sys/dev/usb/if_athn_usb.c), but not until I finish the current device I am working on. It might not be for a while though. There is likely a lot of shared code with ath(4) on FreeBSD (/usr/src/sys/dev/athn). NetBSD seems to separate all code between USB and PCI, whereas FreeBSD combines drivers. Let me know if I can help out, as I already own this device and would be willing to test out code or troubleshoot with you. I am currently working on another driver from Linux to FreeBSD. The core concepts are the same, but a lot of code is in different order. FreeBSD drivers have an attach function that assign function pointers to the softc struct. The Linux equivalent is in DRIVERNAME_ops. In my case, this: http://src.illumos.org/source/xref/linux-master/drivers/net/wireless/realtek/rtlwifi/rtl8188ee/sw.c#224 . Hope this helps. But yes, would love to work on AR9271! -- Farhan Khan PGP Fingerprint: 782F 342B 5B08 0D2F F4E8 82C3 FFA1 CAE1 6536 51CA On Fri, Sep 1, 2017 at 5:25 PM, Thomas Mueller wrote: > from Tecno Linux: > > > Hello, I have the source code of my wireless driver i extract it from the > > linux kernel how can i compile that source code or i have another option > my > > wireless driver is a realtek rtl8723be wifi > > I have similar question, but the source code is from NetBSD and the > wireless chip is Atheros AR9271. > > I also have similar question regarding Ethernet Realtek 8111E re driver, > works in NetBSD but not FreeBSD (11.1-STABLE and HEAD) on computer in > question. > > Is there online handbook/documentation on writing device drivers or > porting from Linux or NetBSD? > > Tom > > ___ > freebsd-wireless@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-wireless > To unsubscribe, send any mail to "freebsd-wireless-unsubscr...@freebsd.org > " > ___ freebsd-wireless@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-wireless To unsubscribe, send any mail to "freebsd-wireless-unsubscr...@freebsd.org"
Re: Adding wifi source code
Here's a pdf giving a decent overview: https://www.bsdcan.org/2006/papers/freebsd.device.driver.slides.pdf But, the FreeBSD handbook also goes over the process as well. https://www.freebsd.org/doc/en_US.ISO8859-1/books/arch-handbook/driverbasics.html For the guy that took Linux drivers, you might want to look into the Linux Emulator, that would be the easiest path especially if those Linux drivers includes a lot of Linux specific headers. The NetBSD drivers should be a bit easier to port.

Re: Adding wifi source code
from Tecno Linux: > Hello, I have the source code of my wireless driver i extract it from the > linux kernel how can i compile that source code or i have another option my > wireless driver is a realtek rtl8723be wifi I have similar question, but the source code is from NetBSD and the wireless chip is Atheros AR9271. I also have similar question regarding Ethernet Realtek 8111E re driver, works in NetBSD but not FreeBSD (11.1-STABLE and HEAD) on computer in question. Is there online handbook/documentation on writing device drivers or porting from Linux or NetBSD?
