[Note: this mail is primarily send for documentation purposes and/or for regzbot, my Linux kernel regression tracking bot. That's why I removed most or all folks from the list of recipients, but left any that looked like a mailing lists. These mails usually contain '#forregzbot' in the subject, to make them easy to spot and filter out.] [TLDR: I'm adding this regression report to the list of tracked regressions; all text from me you find below is based on a few templates paragraphs you might have encountered already already in similar form.] Hi, this is your Linux kernel regression tracker. CCing the regression mailing list, as it should be in the loop for all regressions, as explained here: https://www.kernel.org/doc/html/latest/admin-guide/reporting-issues.html On 21.10.22 10:08, Mikhail Gavrilov wrote: > Hi! > I found that some games (Cyberpunk 2077, Forza Horizon 4/5) hang at > start after commit dd80d9c8eecac8c516da5b240d01a35660ba6cb6. Thanks for the report. To be sure below issue doesn't fall through the cracks unnoticed, I'm adding it to regzbot, my Linux kernel regression tracking bot: #regzbot ^introduced dd80d9c8eecac #regzbot title drm: amdgpu: some games (Cyberpunk 2077, Forza Horizon 4/5) hang at start #regzbot ignore-activity This isn't a regression? This issue or a fix for it are already discussed somewhere else? It was fixed already? You want to clarify when the regression started to happen? Or point out I got the title or something else totally wrong? Then just reply -- ideally with also telling regzbot about it, as explained here: https://linux-regtracking.leemhuis.info/tracked-regression/ Reminder for developers: When fixing the issue, add 'Link:' tags pointing to the report (the mail this one replies to), as explained for in the Linux kernel's documentation; above webpage explains why this is important for tracked regressions. Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) P.S.: As the Linux kernel's regression tracker I deal with a lot of reports and sometimes miss something important when writing mails like this. If that's the case here, don't hesitate to tell me in a public reply, it's in everyone's interest to set the public record straight. > dd80d9c8eecac8c516da5b240d01a35660ba6cb6 is the first bad commit > commit dd80d9c8eecac8c516da5b240d01a35660ba6cb6 > Author: Christian König <christian.koenig@xxxxxxx> > Date: Thu Jul 14 10:23:38 2022 +0200 > > drm/amdgpu: revert "partial revert "remove ctx->lock" v2" > > This reverts commit 94f4c4965e5513ba624488f4b601d6b385635aec. > > We found that the bo_list is missing a protection for its list entries. > Since that is fixed now this workaround can be removed again. > > Signed-off-by: Christian König <christian.koenig@xxxxxxx> > Reviewed-by: Alex Deucher <alexander.deucher@xxxxxxx> > Signed-off-by: Alex Deucher <alexander.deucher@xxxxxxx> > > drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c | 21 ++++++--------------- > drivers/gpu/drm/amd/amdgpu/amdgpu_ctx.c | 2 -- > drivers/gpu/drm/amd/amdgpu/amdgpu_ctx.h | 1 - > 3 files changed, 6 insertions(+), 18 deletions(-) > > > And when it happening in kernel log appears a such backtrace: > [ 231.331210] ------------[ cut here ]------------ > [ 231.331262] WARNING: CPU: 11 PID: 6555 at > drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c:675 > amdgpu_ttm_tt_get_user_pages+0x14c/0x190 [amdgpu] > [ 231.331424] Modules linked in: uinput rfcomm snd_seq_dummy > snd_hrtimer nft_objref nf_conntrack_netbios_ns nf_conntrack_broadcast > nft_fib_inet nft_fib_ipv4 nft_fib_ipv6 nft_fib nft_reject_inet > nf_reject_ipv4 nf_reject_ipv6 nft_reject nft_ct nft_chain_nat nf_nat > nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 ip_set nf_tables nfnetlink > qrtr bnep intel_rapl_msr intel_rapl_common snd_sof_amd_renoir > snd_sof_amd_acp snd_sof_pci snd_hda_codec_realtek snd_sof > snd_hda_codec_generic snd_hda_codec_hdmi snd_sof_utils mt7921e > snd_hda_intel sunrpc snd_intel_dspcfg mt7921_common binfmt_misc > snd_intel_sdw_acpi snd_hda_codec mt76_connac_lib edac_mce_amd btusb > snd_soc_core mt76 snd_hda_core btrtl snd_hwdep snd_compress kvm_amd > ac97_bus snd_seq btbcm snd_pcm_dmaengine btintel snd_rpl_pci_acp6x > mac80211 btmtk snd_pci_acp6x kvm snd_seq_device snd_pcm snd_pci_acp5x > libarc4 irqbypass bluetooth snd_rn_pci_acp3x snd_timer pcspkr > asus_nb_wmi rapl joydev wmi_bmof snd_acp_config cfg80211 snd_soc_acpi > vfat snd > [ 231.331490] snd_pci_acp3x i2c_piix4 soundcore fat k10temp amd_pmc > asus_wireless zram amdgpu drm_ttm_helper ttm hid_asus asus_wmi > iommu_v2 crct10dif_pclmul crc32_pclmul gpu_sched crc32c_intel > ledtrig_audio sparse_keymap polyval_clmulni platform_profile drm_buddy > polyval_generic hid_multitouch drm_display_helper rfkill nvme > ucsi_acpi ghash_clmulni_intel nvme_core video typec_ucsi serio_raw ccp > sha512_ssse3 sp5100_tco r8169 cec nvme_common typec wmi i2c_hid_acpi > i2c_hid ip6_tables ip_tables fuse > [ 231.331532] CPU: 11 PID: 6555 Comm: GameThread Tainted: G W > L ------- --- > 6.1.0-0.rc1.20221019gitaae703b02f92.17.fc38.x86_64 #1 > [ 231.331534] Hardware name: ASUSTeK COMPUTER INC.
