2022-10-17drm/amdgpu: move convert_error_address out of umc_rasHawking Zhang1-4/+12
RAS error address translation algorithm is common across dGPU and A + A platform as along as the SOC integrates the same generation of UMC IP. UMC RAS is managed by x86 MCA on A + A platform, umc_ras in GPU driver is not initialized at all on A + A platform. In such case, any umc_ras callback implemented for dGPU config shouldn't be invoked from A + A specific callback. The change moves convert_error_address out of dGPU umc_ras structure and makes it share between A + A and dGPU config.

2022-09-29drm/amdgpu: Fixed ras warning when uninstalling amdgpuYiPeng Chai1-1/+2
For the asic using smu v13_0_2, there is the following warning when uninstalling amdgpu: amdgpu: ras disable gfx failed poison:1 ret:-22. [Why]: For the asic using smu v13_0_2, the psp .suspend and mode1reset is called before amdgpu_ras_pre_fini during amdgpu uninstall, it has disabled all ras features and reset the psp. Since the psp is reset, calling amdgpu_ras_disable_all_features in amdgpu_ras_pre_fini to disable ras features will fail. [How]: If all ras features are disabled, amdgpu_ras_disable_all_features will not be called to disable all ras features again.

2022-02-02drm/amdgpu: Add judgement to avoid infinite loopyipechai1-0/+4
1. The infinite loop causing soft lock occurs on multiple amdgpu cards supporting ras feature. 2. This a workaround patch to fix 6492e1b07c03397f85bd6dc0e230ea6cd9394635. It is valid for multiple amdgpu cards of the same type. 3. The root cause is that each GPU card device has a separate .ras_list link header, but the instance and linked list node of each ras block are unique. When each device is initialized, each ras instance will repeatedly add link node to the device every time. In this way, only the .ras_list of the last initialized device is completely correct. the .ras_list->prev and .ras_list->next of the device initialzied before can still point to the correct ras instance, but the prev pointer and next pointer of the pointed ras instance both point to the last initialized device's .ras_ list instead of the beginning .ras_ list. When using list_for_each_entry_safe searches for non-existent Ras nodes on devices other than the last device, the last ras instance next pointer cannot always be equal to the beginning .ras_list, so that the loop cannot be terminated, the program enters a infinite loop. BTW: Since the data and initialization process of each card are the same, the link list between ras instances will not be destroyed every time the device is initialized. 4. The soft locked logs are as follows: [ 262.165690] CPU: 93 PID: 758 Comm: kworker/93:1 Tainted: G OE 5.13.0-27-generic #29~20.04.1-Ubuntu [ 262.165695] Hardware name: Supermicro AS -4124GS-TNR/H12DSG-O-CPU, BIOS T20200717143848 07/17/2020 [ 262.165698] Workqueue: events amdgpu_ras_do_recovery [amdgpu] [ 262.165980] RIP: 0010:amdgpu_ras_get_ras_block+0x86/0xd0 [amdgpu] [ 262.166239] Code: 68 d8 4c 8d 71 d8 48 39 c3 74 54 49 8b 45 38 48 85 c0 74 32 44 89 fa 44 89 e6 4c 89 ef e8 82 e4 9b dc 85 c0 74 3c 49 8b 46 28 <49> 8d 56 28 4d 89 f5 48 83 e8 28 48 39 d3 74 25 49 89 c6 49 8b 45 [ 262.166243] RSP: 0018:ffffac908fa87d80 EFLAGS: 00000202 [ 262.166247] RAX: ffffffffc1394248 RBX: ffff91e4ab8d6e20 RCX: ffffffffc1394248 [ 262.166249] RDX: ffff91e4aa356e20 RSI: 000000000000000e RDI: ffff91e4ab8c0000 [ 262.166252] RBP: ffffac908fa87da8 R08: 0000000000000007 R09: 0000000000000001 [ 262.166254] R10: ffff91e4930b64ec R11: 0000000000000000 R12: 000000000000000e [ 262.166256] R13: ffff91e4aa356df8 R14: ffffffffc1394320 R15: 0000000000000003 [ 262.166258] FS: 0000000000000000(0000) GS:ffff92238fb40000(0000) knlGS:0000000000000000 [ 262.166261] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 262.166264] CR2: 00000001004865d0 CR3: 000000406d796000 CR4: 0000000000350ee0 [ 262.166267] Call Trace: [ 262.166272] amdgpu_ras_do_recovery+0x130/0x290 [amdgpu] [ 262.166529] ? psi_task_switch+0xd2/0x250 [ 262.166537] ? __switch_to+0x11d/0x460 [ 262.166542] ? __switch_to_asm+0x36/0x70 [ 262.166549] process_one_work+0x220/0x3c0 [ 262.166556] worker_thread+0x4d/0x3f0 [ 262.166560] ? process_one_work+0x3c0/0x3c0 [ 262.166563] kthread+0x12b/0x150 [ 262.166568] ? set_kthread_struct+0x40/0x40 [ 262.166571] ret_from_fork+0x22/0x30 Fixes: 6492e1b07c0339 ("drm/amdgpu: Unify ras block interface for each ras block") Signed-off-by: yipechai <[email protected]> Reviewed-by: John Clements <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

Xgmi ras initialization had been moved from .late_init to early_init, the defect of repeated calling amdgpu_ras_register_ras_block had been fixed, so revert this patch.
