Package: src:linux Version: 4.15.4-1 Severity: important Tags: upstream -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512
Hi, The introduction of commit dc911f5bd8aa (drm/i915/edp: Allow alternate fixed mode for eDP if available.) causes severe performance degradations on my system, especially noticeable while playing video games. There are some workarounds though: - - Setting the screen refresh rate below 60 Hz. Might be inconvenient in certain circumstances. - - Using Jim Bride’s patch¹. According to some people it cures the issue. Contrary to the above workaround, this one I did not test. It should be noted that it seems to have fall through the cracks as I don’t see any reference to it in Linus' tree. As we are going to use 4.15.x for some more time, I propose that we revert the aforementioned commit until a solution is found upstream. Thought? Cheers, Vincent ¹ https://bugs.freedesktop.org/attachment.cgi?id=135277 - -- Package-specific info: ** Version: Linux version 4.15.0-1-amd64 (debian-ker...@lists.debian.org) (gcc version 7.3.0 (Debian 7.3.0-3)) #1 SMP Debian 4.15.4-1 (2018-02-18) ** Command line: BOOT_IMAGE=/boot/vmlinuz-4.15.0-1-amd64 root=UUID=05885802-d6d1-4a25-b7ef-8c3e00c144b0 ro quiet pcie_aspm=force elevator=deadline intel_pstate=disable apparmor=1 security=apparmor ** Tainted: U (64) * Userspace-defined naughtiness. ** Kernel log: Unable to read kernel log; any relevant messages should be attached ** Model information sys_vendor: ASUSTeK COMPUTER INC. product_name: UX31A product_version: 1.0 chassis_vendor: ASUSTeK COMPUTER INC. chassis_version: 1.0 bios_vendor: American Megatrends Inc. bios_version: UX31A.219 board_vendor: ASUSTeK COMPUTER INC. board_name: UX31A board_version: 1.0 ** Loaded modules: xt_CHECKSUM iptable_mangle devlink ipt_MASQUERADE nf_nat_masquerade_ipv4 iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 nf_nat nf_conntrack xt_tcpudp bridge stp llc iptable_filter ctr ccm fuse arc4 binfmt_misc uvcvideo videobuf2_vmalloc videobuf2_memops videobuf2_v4l2 videobuf2_core intel_rapl btusb videodev x86_pkg_temp_thermal iTCO_wdt intel_powerclamp coretemp media btrtl iTCO_vendor_support asus_nb_wmi btbcm asus_wmi kvm_intel btintel sparse_keymap rtsx_usb_ms bluetooth memstick kvm irqbypass drbg crct10dif_pclmul snd_hda_codec_hdmi ansi_cprng crc32_pclmul snd_hda_codec_realtek snd_hda_codec_generic ecdh_generic ghash_clmulni_intel intel_cstate iwlmvm mac80211 iwlwifi intel_uncore intel_rapl_perf evdev joydev pcspkr serio_raw snd_hda_intel snd_hda_codec cfg80211 i915 snd_hda_core rfkill snd_hwdep lpc_ich drm_kms_helper sg shpchp snd_pcm snd_timer snd drm soundcore i2c_algo_bit wmi button int3403_thermal acpi_als kfifo_buf video battery industrialio ac int3402_thermal int340x_thermal_zone int3400_thermal asus_wireless acpi_thermal_rel acpi_cpufreq ib_iser rdma_cm iw_cm ib_cm ib_core configfs iscsi_tcp libiscsi_tcp libiscsi scsi_transport_iscsi loop parport_pc ppdev lp parport sunrpc ip_tables x_tables autofs4 ext4 crc16 mbcache jbd2 fscrypto ecb rtsx_usb_sdmmc mmc_core rtsx_usb mfd_core btrfs zstd_decompress zstd_compress xxhash raid10 raid456 async_raid6_recov async_memcpy async_pq async_xor async_tx xor hid_generic usbhid hid raid6_pq libcrc32c crc32c_generic raid1 raid0 multipath linear md_mod sd_mod crc32c_intel aesni_intel ahci libahci i2c_i801 aes_x86_64 xhci_pci crypto_simd cryptd glue_helper libata ehci_pci xhci_hcd ehci_hcd psmouse scsi_mod usbcore usb_common thermal fan ** PCI devices: 00:00.0 Host bridge [0600]: Intel Corporation 3rd Gen Core processor DRAM Controller [8086:0154] (rev 09) Subsystem: ASUSTeK Computer Inc.
