A bad job is the one triggered TDR(In the current amdgpu's implementation, actually all the jobs in the current joq-queue will be treated as bad jobs). In the recovery process, its fence will be fake signaled and as a result, the work behind will be scheduled to delete it from the mirror list, but if the TDR process is invoked before the work's execution, then this bad job might be processed again and the call dma_fence_set_error to its fence in TDR process will lead to kernel warning trace: [ 143.033605] WARNING: CPU: 2 PID: 53 at ./include/linux/dma-fence.h:437 amddrm_sched_job_recovery+0x1af/0x1c0 [amd_sched] kernel: [ 143.033606] Modules linked in: amdgpu(OE) amdchash(OE) amdttm(OE) amd_sched(OE) amdkcl(OE) amd_iommu_v2 drm_kms_helper drm i2c_algo_bit fb_sys_fops syscopyarea sysfillrect sysimgblt kvm_intel kvm irqbypass crct10dif_pclmul crc32_pclmul ghash_clmulni_intel pcbc aesni_intel aes_x86_64 snd_hda_codec_generic crypto_simd glue_helper cryptd snd_hda_intel snd_hda_codec snd_hda_core snd_hwdep snd_pcm snd_seq_midi snd_seq_midi_event snd_rawmidi snd_seq joydev snd_seq_device snd_timer snd soundcore binfmt_misc input_leds mac_hid serio_raw nfsd auth_rpcgss nfs_acl lockd grace sunrpc sch_fq_codel parport_pc ppdev lp parport ip_tables x_tables autofs4 8139too floppy psmouse 8139cp mii i2c_piix4 pata_acpi [ 143.033649] CPU: 2 PID: 53 Comm: kworker/2:1 Tainted: G OE 4.15.0-20-generic #21-Ubuntu [ 143.033650] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS Ubuntu-1.8.2-1ubuntu1 04/01/2014 [ 143.033653] Workqueue: events drm_sched_job_timedout [amd_sched] [ 143.033656] RIP: 0010:amddrm_sched_job_recovery+0x1af/0x1c0 [amd_sched] [ 143.033657] RSP: 0018:ffffa9f880fe7d48 EFLAGS: 00010202 [ 143.033659] RAX: 0000000000000007 RBX: ffff9b98f2b24c00 RCX: ffff9b98efef4f08 [ 143.033660] RDX: ffff9b98f2b27400 RSI: ffff9b98f2b24c50 RDI: ffff9b98efef4f18 [ 143.033660] RBP: ffffa9f880fe7d98 R08: 0000000000000001 R09: 00000000000002b6 [ 143.033661] R10: 0000000000000000 R11: 0000000000000000 R12: ffff9b98efef3430 [ 143.033662] R13: ffff9b98efef4d80 R14: ffff9b98efef4e98 R15: ffff9b98eaf91c00 [ 143.033663] FS: 0000000000000000(0000) GS:ffff9b98ffd00000(0000) knlGS:0000000000000000 [ 143.033664] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 143.033665] CR2: 00007fc49c96d470 CR3: 000000001400a005 CR4: 00000000003606e0 [ 143.033669] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 143.033669] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 143.033670] Call Trace: [ 143.033744] amdgpu_device_gpu_recover+0x144/0x820 [amdgpu] [ 143.033788] amdgpu_job_timedout+0x9b/0xa0 [amdgpu] [ 143.033791] drm_sched_job_timedout+0xcc/0x150 [amd_sched] [ 143.033795] process_one_work+0x1de/0x410 [ 143.033797] worker_thread+0x32/0x410 [ 143.033799] kthread+0x121/0x140 [ 143.033801] ? process_one_work+0x410/0x410 [ 143.033803] ? kthread_create_worker_on_cpu+0x70/0x70 [ 143.033806] ret_from_fork+0x35/0x40 So just delete the bad job from mirror list directly Changes in v3: - Add a helper function to delete the bad jobs from mirror list and call it directly *before* the job's fence is signaled Changes in v2: - delete the useless list node check - also delete bad jobs in drm_sched_main because: kthread_unpark(ring->sched.thread) will be invoked very early before amdgpu_device_gpu_recover's return, then drm_sched_main will have chance to pick up a new job from the job queue. This new job will be added into the mirror list and processed by amdgpu_job_run, but may not be deleted from the mirror list on time due to the same reason.

[Why] Many panels support more than 8bpc but some modes are unavailable while running at greater than 8bpc due to DP/HDMI bandwidth constraints. Support for more than 8bpc was added recently in the driver but it defaults to the maximum supported bpc - locking out these modes. This should be a user configurable option such that the user can select what bpc configuration they would like. [How] This patch adds support for getting and setting the amdgpu driver specific "max bpc" property on the connector. It also adds support for limiting the output bpc based on the property value. The default limitation is the lowest value in the range, 8bpc. This was the old value before the range was uncapped. This patch should be updated/replaced later once common drm support for max bpc lands.

[How] This patch introduces the "max bpc" amdgpu driver specific connector property so the user can limit the maximum bpc. It ranges from 8 to 16. This doesn't directly set the preferred bpc for the panel since it follows Intel's existing driver conventions.

[why] phy_pix_clk is one of the variable used to check if one PLL can be shared with displays having common mode set configuration. As of now phy_pix_clock varialbe is calculated in function dc_validate_stream(). dc_validate_stream() function is called after clocks are assigned for the new display. Due to this during hotplug, when PLL sharing conditions are checked for new display phy_pix_clk variable will be 0 and for displays that are already enabled phy_pix_clk will have some value. Hence PLL will not be shared and if the display hardware doesn't have any more PLL to assign, mode set will fail due to resource unavailability. [how] Instead of only calculating the phy_pix_clk variable after the PLL is assigned for new display, this patch calculates phy_pix_clk also during the before assigning the PLL for new display.

The unit tests are not critical to fix, but no reason to hold this fix back. Summary: - Address Range Scrub overflow continuation handling has been broken since it was initially merged. It was only recently that error injection and platform-BIOS support enabled this corner case to be exercised. - The recent attempt to provide more isolation for the kernel Address Range Scrub state machine from userapace initiated sessions triggers a lockdep report.
