1. The infinite loop causing soft lock occurs on multiple amdgpu cards supporting ras feature. 2. This a workaround patch to fix 6492e1b0. 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: 6492e1b0 ("drm/amdgpu: Unify ras block interface for each ras block") Signed-off-by:

Mario Limonciello authored
On some OEM setups users can configure the BIOS for S3 or S2idle. When configured to S3 users can still choose 's2idle' in the kernel by using `/sys/power/mem_sleep`. Before commit 6dc8265f ("drm/amdgpu: always reset the asic in suspend (v2)"), the GPU would crash. Now when configured this way, the system should resume but will use more power. As such, adjust the `amdpu_acpi_is_s0ix function` to warn users about potential power consumption issues during their first attempt at suspending. Reported-by:

Add a new CTX ioctl operation to set stable pstates for profiling. When creating traces for tools like RGP or using SPM or doing performance profiling, it's required to enable a special stable profiling power state on the GPU. These profiling states set fixed clocks and disable certain other power features like powergating which may impact the results. Historically, these profiling pstates were enabled via sysfs, but this adds an interface to enable it via the CTX ioctl from the application. Since the power state is global only one application can set it at a time, so if multiple applications try and use it only the first will get it, the ioctl will return -EBUSY for others. The sysfs interface will override whatever has been set by this interface.
