2024-03-15drm/nouveau/dp: Fix incorrect return code in r535_dp_aux_xfer()Lyude Paul
I've recently been seeing some unexplained GSP errors on my RTX 6000 from failed aux transactions: [ 132.915867] nouveau 0000:1f:00.0: gsp: cli:0xc1d00002 obj:0x00730000 ctrl cmd:0x00731341 failed: 0x0000ffff While the cause of these is not yet clear, these messages made me notice that the aux transactions causing these transactions were succeeding - not failing. As it turns out, this is because we're currently not returning the correct variable when r535_dp_aux_xfer() hits an error - causing us to never propagate GSP errors for failed aux transactions to userspace. So, let's fix that.

2024-03-15drm/sched: fix null-ptr-deref in init entityVitaly Prosyak
The bug can be triggered by sending an amdgpu_cs_wait_ioctl to the AMDGPU DRM driver on any ASICs with valid context. The bug was reported by Joonkyo Jung <joonkyoj@yonsei.ac.kr>. For example the following code: static void Syzkaller2(int fd) { union drm_amdgpu_ctx arg1; union drm_amdgpu_wait_cs arg2; arg1.in.op = AMDGPU_CTX_OP_ALLOC_CTX; ret = drmIoctl(fd, 0x140106442 /* amdgpu_ctx_ioctl */, &arg1); arg2.in.handle = 0x0; arg2.in.timeout = 0x2000000000000; arg2.in.ip_type = AMD_IP_VPE /* 0x9 */; arg2->in.ip_instance = 0x0; arg2.in.ring = 0x0; arg2.in.ctx_id = arg1.out.alloc.ctx_id; drmIoctl(fd, 0xc0206449 /* AMDGPU_WAIT_CS * /, &arg2); } The ioctl AMDGPU_WAIT_CS without previously submitted job could be assumed that the error should be returned, but the following commit 1decbf6bb0b4dc56c9da6c5e57b994ebfc2be3aa modified the logic and allowed to have sched_rq equal to NULL. As a result when there is no job the ioctl AMDGPU_WAIT_CS returns success. The change fixes null-ptr-deref in init entity and the stack below demonstrates the error condition: [ +0.000007] BUG: kernel NULL pointer dereference, address: 0000000000000028 [ +0.007086] #PF: supervisor read access in kernel mode [ +0.005234] #PF: error_code(0x0000) - not-present page [ +0.005232] PGD 0 P4D 0 [ +0.002501] Oops: 0000 [#1] PREEMPT SMP KASAN NOPTI [ +0.005034] CPU: 10 PID: 9229 Comm: amd_basic Tainted: G B W L 6.7.0+ #4 [ +0.007797] Hardware name: ASUS System Product Name/ROG STRIX B550-F GAMING (WI-FI), BIOS 1401 12/03/2020 [ +0.009798] RIP: 0010:drm_sched_entity_init+0x2d3/0x420 [gpu_sched] [ +0.006426] Code: 80 00 00 00 00 00 00 00 e8 1a 81 82 e0 49 89 9c 24 c0 00 00 00 4c 89 ef e8 4a 80 82 e0 49 8b 5d 00 48 8d 7b 28 e8 3d 80 82 e0 <48> 83 7b 28 00 0f 84 28 01 00 00 4d 8d ac 24 98 00 00 00 49 8d 5c [ +0.019094] RSP: 0018:ffffc90014c1fa40 EFLAGS: 00010282 [ +0.005237] RAX: 0000000000000001 RBX: 0000000000000000 RCX: ffffffff8113f3fa [ +0.007326] RDX: fffffbfff0a7889d RSI: 0000000000000008 RDI: ffffffff853c44e0 [ +0.007264] RBP: ffffc90014c1fa80 R08: 0000000000000001 R09: fffffbfff0a7889c [ +0.007266] R10: ffffffff853c44e7 R11: 0000000000000001 R12: ffff8881a719b010 [ +0.007263] R13: ffff88810d412748 R14: 0000000000000002 R15: 0000000000000000 [ +0.007264] FS: 00007ffff7045540(0000) GS:ffff8883cc900000(0000) knlGS:0000000000000000 [ +0.008236] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ +0.005851] CR2: 0000000000000028 CR3: 000000011912e000 CR4: 0000000000350ef0 [ +0.007175] Call Trace: [ +0.002561] <TASK> [ +0.002141] ?

commit 64f6a5d1922b ("container_of: add container_of_const() that preserves const-ness of the pointer") is nice. Let's use it so that we don't accidentally cast away the const from our state pointers. The only thing I don't particularly like about container_of_const() is that it still accepts void* in addition to the proper pointer types, but that's how most other things in C work anyway so I guess we can live with it.

2024-03-14drm/xe/gsc: Handle GSCCS ER interruptDaniele Ceraolo Spurio
Starting on Xe2, the GSCCS engine reset is a 2-step process. When the driver or the GuC hits the GDRST register, the CS is immediately reset and a success is reported, but the GSC shim continues its reset in the background. While the shim reset is ongoing, the CS is able to accept new context submission, but any commands that require the shim will be stalled until the reset is completed. This means that we can keep submitting to the GSCCS as long as we make sure that the preemption timeout is big enough to cover any delay introduced by the reset; since the GSC preempt timeout is not tunable at runtime, we only need to check that the value set in kconfig is big enough (and increase it if it isn't). When the shim reset completes, a specific CS interrupt is triggered, in response to which we need to check the GSCI_TIMER_STATUS register to see if the reset was successful or not. Note that the GSCI_TIMER_STATUS register is not power save/restored, so it gets reset on MC6 entry. However, a reset failure stops MC6, so in that scenario we're always guaranteed to find the correct value. Since we can't check the register within interrupt context, the existing GSC worker has been updated to handle it. The expected action to take on ER failure is to trigger a driver FLR, but we still don't support that, so for now we just print an error. A comment has been added to the code to keep track of the FLR requirement. v2: Add a check for the initial timeout value (Alan) Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Alan Previn <alan.previn.teres.alexis@intel.com> Reviewed-by: Alan Previn <alan.previn.teres.alexis@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240304145634.820684-1-daniele.ceraolospurio@intel.com
2024-03-14drm/xe: Skip VMAs pin when requesting signal to the last XE_EXECJosé Roberto de Souza
Doing a XE_EXEC with num_batch_buffer == 0 makes signals passed as argument to be signaled when the last real XE_EXEC is completed. But to do that it was first pinning all VMAs in drm_gpuvm_exec_lock(), this patch remove this pinning as it is not required. This change also help Mesa implementing memory over-commiting recovery as it needs to unbind not needed VMAs when the whole VM can't fit in GPU memory but it can only do the unbiding when the last XE_EXEC is completed. So with this change Mesa can get the signal it want without getting out-of-memory errors.
