It does look like it might be buggy... Anyway, it doesn't hurt to set "r" to zero at the start. Reviewed-by:

I've reviewed the code, and that seems possible, but it's also possible I may have missed something. Reviewed-by:

Function vega10_apply_state_adjust_rules() only initializes stable_pstate_sclk_dpm_percentage when data->registry_data.stable_pstate_sclk_dpm_percentage is not between 1 and 100. The variable is then used to compute stable_pstate_sclk, which therefore uses an uninitialized value. Fix this by initializing stable_pstate_sclk_dpm_percentage to data->registry_data.stable_pstate_sclk_dpm_percentage. This issue has been found while building the kernel with clang. The compiler reported a -Wsometimes-uninitialized warning. Reviewed-by:

Since commit 632c6e4e ("drm/vblank: Fix flip event vblank count") even drivers that don't implement accurate vblank timestamps will end up using drm_crtc_accurate_vblank_count(). That leads to a WARN every time drm_crtc_arm_vblank_event() gets called. The could be as often as every frame for each active crtc. Considering drm_crtc_accurate_vblank_count() is never any worse than the drm_vblank_count() we used previously, let's just skip the WARN unless DRM_UT_VBL is enabled. That way people won't be bothered by this unless they're debugging vblank code. And let's also change it to WARN_ONCE() so that even when you're debugging vblank code you won't get drowned by constant WARNs.

Memory allocation failure should generally be handled gracefully by callers. In particular, with transparent hugepage support, attempts to allocate huge pages can fail under memory pressure, but the callers fall back to allocating individual pages instead. In that case, there would be spurious [TTM] Unable to get page %u error messages in dmesg. Reviewed-by:

Accessing the THIS_MODULE directly is only possible when modules are enabled, otherwise we get a build failure: drivers/gpu/drm/amd/amdgpu/amdgpu_virt.c: In function 'amdgpu_virt_init_data_exchange': drivers/gpu/drm/amd/amdgpu/amdgpu_virt.c:331:20: error: dereferencing pointer to incomplete type 'struct module' Further, THIS_MODULE is NULL when the driver is built-in, so the code would likely cause a NULL pointer dereference. This adds an #ifdef check to avoid the compile-time error, plus a NULL pointer check before dereferencing THIS_MODULE. It might be better to find a way to avoid using the module version altogether.
