2020-07-27drm/amdgpu: fix system hang issue during GPU resetDennis Li
when GPU hang, driver has multi-paths to enter amdgpu_device_gpu_recover, the atomic adev->in_gpu_reset and hive->in_reset are used to avoid re-entering GPU recovery. During GPU reset and resume, it is unsafe that other threads access GPU, which maybe cause GPU reset failed. Therefore the new rw_semaphore adev->reset_sem is introduced, which protect GPU from being accessed by external threads during recovery. v2: 1. add rwlock for some ioctls, debugfs and file-close function. 2. change to use dqm->is_resetting and dqm_lock for protection in kfd driver. 3. remove try_lock and change adev->in_gpu_reset as atomic, to avoid re-enter GPU recovery for the same GPU hang. v3: 1. change back to use adev->reset_sem to protect kfd callback functions, because dqm_lock couldn't protect all codes, for example: free_mqd must be called outside of dqm_lock; [ 1230.176199] Hardware name: Supermicro SYS-7049GP-TRT/X11DPG-QT, BIOS 3.1 05/23/2019 [ 1230.177221] Call Trace: [ 1230.178249] dump_stack+0x98/0xd5 [ 1230.179443] amdgpu_virt_kiq_reg_write_reg_wait+0x181/0x190 [amdgpu] [ 1230.180673] gmc_v9_0_flush_gpu_tlb+0xcc/0x310 [amdgpu] [ 1230.181882] amdgpu_gart_unbind+0xa9/0xe0 [amdgpu] [ 1230.183098] amdgpu_ttm_backend_unbind+0x46/0x180 [amdgpu] [ 1230.184239] ? ttm_bo_put+0x171/0x5f0 [ttm] [ 1230.185394] ttm_tt_unbind+0x21/0x40 [ttm] [ 1230.186558] ttm_tt_destroy.part.12+0x12/0x60 [ttm] [ 1230.187707] ttm_tt_destroy+0x13/0x20 [ttm] [ 1230.188832] ttm_bo_cleanup_memtype_use+0x36/0x80 [ttm] [ 1230.189979] ttm_bo_put+0x1be/0x5f0 [ttm] [ 1230.191230] amdgpu_bo_unref+0x1e/0x30 [amdgpu] [ 1230.192522] amdgpu_amdkfd_free_gtt_mem+0xaf/0x140 [amdgpu] [ 1230.193833] free_mqd+0x25/0x40 [amdgpu] [ 1230.195143] destroy_queue_cpsch+0x1a7/0x270 [amdgpu] [ 1230.196475] pqm_destroy_queue+0x105/0x260 [amdgpu] [ 1230.197819] kfd_ioctl_destroy_queue+0x37/0x70 [amdgpu] [ 1230.199154] kfd_ioctl+0x277/0x500 [amdgpu] [ 1230.200458] ? kfd_ioctl_get_clock_counters+0x60/0x60 [amdgpu] [ 1230.201656] ? tomoyo_file_ioctl+0x19/0x20 [ 1230.202831] ksys_ioctl+0x98/0xb0 [ 1230.204004] __x64_sys_ioctl+0x1a/0x20 [ 1230.205174] do_syscall_64+0x5f/0x250 [ 1230.206339] entry_SYSCALL_64_after_hwframe+0x49/0xbe 2. remove try_lock and introduce atomic hive->in_reset, to avoid re-enter GPU recovery. v4: 1. remove an unnecessary whitespace change in kfd_chardev.c 2. remove comment codes in amdgpu_device.c 3. add more detailed comment in commit message 4. define a wrap function amdgpu_in_reset v5: 1.

2020-07-01drm/amdgpu: Fix a buffer overflow handling the serial numberDan Carpenter
The comments say that the serial number is a 16-digit HEX string so the buffer needs to be at least 17 characters to hold the NUL terminator. The other issue is that "size" returned from sprintf() is the number of characters before the NUL terminator so the memcpy() wasn't copying the terminator. The serial number needs to be NUL terminated so that it doesn't lead to a read overflow in amdgpu_device_get_serial_number(). Also it's just cleaner and faster to sprintf() directly to adev->serial[] instead of using a temporary buffer.

2020-05-18drm/amdgpu: Add autodump debugfs node for gpu reset v8Jiange Zhao
When GPU got timeout, it would notify an interested part of an opportunity to dump info before actual GPU reset. A usermode app would open 'autodump' node under debugfs system and poll() for readable/writable. When a GPU reset is due, amdgpu would notify usermode app through wait_queue_head and give it 10 minutes to dump info. After usermode app has done its work, this 'autodump' node is closed. On node closure, amdgpu gets to know the dump is done through the completion that is triggered in release(). There is no write or read callback because necessary info can be obtained through dmesg and umr. Messages back and forth between usermode app and amdgpu are unnecessary. v2: (1) changed 'registered' to 'app_listening' (2) add a mutex in open() to prevent race condition v3 (chk): grab the reset lock to avoid race in autodump_open, rename debugfs file to amdgpu_autodump, provide autodump_read as well, style and code cleanups v4: add 'bool app_listening' to differentiate situations, so that the node can be reopened; also, there is no need to wait for completion when no app is waiting for a dump. v5: change 'bool app_listening' to 'enum amdgpu_autodump_state' add 'app_state_mutex' for race conditions: (1)Only 1 user can open this file node (2)wait_dump() can only take effect after poll() executed. (3)eliminated the race condition between release() and wait_dump() v6: removed 'enum amdgpu_autodump_state' and 'app_state_mutex' removed state checking in amdgpu_debugfs_wait_dump Improve on top of version 3 so that the node can be reopened. v7: move reinit_completion into open() so that only one user can open it. v8: remove complete_all() from amdgpu_debugfs_wait_dump().

Implement an accessor of adev->tmz.enabled. Let not code around access it as "if (adev->tmz.enabled)" as the organization may change. Instead... Recruit "bool amdgpu_is_tmz(adev)" to return exactly this Boolean value. That is, this function is now an accessor of an already initialized and set adev and adev->tmz. Add "void amdgpu_gmc_tmz_set(adev)" to check and set adev->gmc.tmz_enabled at initialization time. After which one uses "bool amdgpu_is_tmz(adev)" to query whether adev supports TMZ. Also, remove circular header file include. v2: Remove amdgpu_tmz.[ch] as requested. v3: Move TMZ into GMC.
