2022-11-09drm/amdkfd: Fix error handling in criu_checkpointFelix Kuehling1-19/+15
Checkpoint BOs last. That way we don't need to close dmabuf FDs if something else fails later. This avoids problematic access to user mode memory in the error handling code path. criu_checkpoint_bos has its own error handling and cleanup that does not depend on access to user memory. In the private data, keep BOs before the remaining objects. This is necessary to restore things in the correct order as restoring events depends on the events-page BO being restored first.

2022-11-04drm/amdgpu: Fix type of second parameter in odn_edit_dpm_table() callbackNathan Chancellor2-2/+4
With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG), indirect call targets are validated against the expected function pointer prototype to make sure the call target is valid to help mitigate ROP attacks. If they are not identical, there is a failure at run time, which manifests as either a kernel panic or thread getting killed. A proposed warning in clang aims to catch these at compile time, which reveals: drivers/gpu/drm/amd/amdgpu/../pm/swsmu/amdgpu_smu.c:3008:29: error: incompatible function pointer types initializing 'int (*)(void *, uint32_t, long *, uint32_t)' (aka 'int (*)(void *, unsigned int, long *, unsigned int)') with an expression of type 'int (void *, enum PP_OD_DPM_TABLE_COMMAND, long *, uint32_t)' (aka 'int (void *, enum PP_OD_DPM_TABLE_COMMAND, long *, unsigned int)') [-Werror,-Wincompatible-function-pointer-types-strict] .odn_edit_dpm_table = smu_od_edit_dpm_table, ^~~~~~~~~~~~~~~~~~~~~ 1 error generated. There are only two implementations of ->odn_edit_dpm_table() in 'struct amd_pm_funcs': smu_od_edit_dpm_table() and pp_odn_edit_dpm_table(). One has a second parameter type of 'enum PP_OD_DPM_TABLE_COMMAND' and the other uses 'u32'. Ultimately, smu_od_edit_dpm_table() calls ->od_edit_dpm_table() from 'struct pptable_funcs' and pp_odn_edit_dpm_table() calls ->odn_edit_dpm_table() from 'struct pp_hwmgr_func', which both have a second parameter type of 'enum PP_OD_DPM_TABLE_COMMAND'. Update the type parameter in both the prototype in 'struct amd_pm_funcs' and pp_odn_edit_dpm_table() to 'enum PP_OD_DPM_TABLE_COMMAND', which cleans up the warning.

2022-11-04drm/amdgpu: Replace one-element array with flexible-array memberPaulo Miguel Almeida2-3/+6
One-element arrays are deprecated, and we are replacing them with flexible array members instead. So, replace one-element array with flexible-array member in struct _ATOM_FAKE_EDID_PATCH_RECORD and refactor the rest of the code accordingly. Important to mention is that doing a build before/after this patch results in no binary output differences. This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -fstrict-flex-arrays=3 [1].

2022-11-01drm/amd/display: Stop waiting for vblank during pipe programmingMartin Leung1-1/+0
[why and how] This line was originally removed for a compliance issue, but then reverted as it caused a fringe underflow case.
