Dave Airlie bafaf67c42 Revert "drm/sched: Use parent fence instead of finished" This reverts commit `e4dc45b184`. This is causing instability on Linus' desktop, and I'm seeing oops with VK CTS runs. netconsole got me the following oops: [ 1234.778760] BUG: kernel NULL pointer dereference, address: 0000000000000088 [ 1234.778782] #PF: supervisor read access in kernel mode [ 1234.778787] #PF: error_code(0x0000) - not-present page [ 1234.778791] PGD 0 P4D 0 [ 1234.778798] Oops: 0000 [#1] PREEMPT SMP NOPTI [ 1234.778803] CPU: 7 PID: 805 Comm: systemd-journal Not tainted 6.0.0+ #2 [ 1234.778809] Hardware name: System manufacturer System Product Name/PRIME X370-PRO, BIOS 5603 07/28/2020 [ 1234.778813] RIP: 0010:drm_sched_job_done.isra.0+0xc/0x140 [gpu_sched] [ 1234.778828] Code: aa 0f 1d ce e9 57 ff ff ff 48 89 d7 e8 9d 8f 3f ce e9 4a ff ff ff 0f 1f 84 00 00 00 00 00 0f 1f 44 00 00 41 54 55 53 48 89 fb <48> 8b af 88 00 00 00 f0 ff 8d f0 00 00 00 48 8b 85 80 01 00 00 f0 [ 1234.778834] RSP: 0000:ffffabe680380de0 EFLAGS: 00010087 [ 1234.778839] RAX: ffffffffc04e9230 RBX: 0000000000000000 RCX: 0000000000000018 [ 1234.778897] RDX: 00000ba278e8977a RSI: ffff953fb288b460 RDI: 0000000000000000 [ 1234.778901] RBP: ffff953fb288b598 R08: 00000000000000e0 R09: ffff953fbd98b808 [ 1234.778905] R10: 0000000000000000 R11: ffffabe680380ff8 R12: ffffabe680380e00 [ 1234.778908] R13: 0000000000000001 R14: 00000000ffffffff R15: ffff953fbd9ec458 [ 1234.778912] FS: 00007f35e7008580(0000) GS:ffff95428ebc0000(0000) knlGS:0000000000000000 [ 1234.778916] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 1234.778919] CR2: 0000000000000088 CR3: 000000010147c000 CR4: 00000000003506e0 [ 1234.778924] Call Trace: [ 1234.778981] <IRQ> [ 1234.778989] dma_fence_signal_timestamp_locked+0x6a/0xe0 [ 1234.778999] dma_fence_signal+0x2c/0x50 [ 1234.779005] amdgpu_fence_process+0xc8/0x140 [amdgpu] [ 1234.779234] sdma_v3_0_process_trap_irq+0x70/0x80 [amdgpu] [ 1234.779395] amdgpu_irq_dispatch+0xa9/0x1d0 [amdgpu] [ 1234.779609] amdgpu_ih_process+0x80/0x100 [amdgpu] [ 1234.779783] amdgpu_irq_handler+0x1f/0x60 [amdgpu] [ 1234.779940] __handle_irq_event_percpu+0x46/0x190 [ 1234.779946] handle_irq_event+0x34/0x70 [ 1234.779949] handle_edge_irq+0x9f/0x240 [ 1234.779954] __common_interrupt+0x66/0x100 [ 1234.779960] common_interrupt+0xa0/0xc0 [ 1234.779965] </IRQ> [ 1234.779968] <TASK> [ 1234.779971] asm_common_interrupt+0x22/0x40 [ 1234.779976] RIP: 0010:finish_mkwrite_fault+0x22/0x110 [ 1234.779981] Code: 1f 84 00 00 00 00 00 90 0f 1f 44 00 00 41 55 41 54 55 48 89 fd 53 48 8b 07 f6 40 50 08 0f 84 eb 00 00 00 48 8b 45 30 48 8b 18 <48> 89 df e8 66 bd ff ff 48 85 c0 74 0d 48 89 c2 83 e2 01 48 83 ea [ 1234.779985] RSP: 0000:ffffabe680bcfd78 EFLAGS: 00000202 Revert it for now and figure it out later.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
