2023-12-13drm/amdkfd: Import DMABufs for interop through DRMFelix Kuehling
Use drm_gem_prime_fd_to_handle to import DMABufs for interop. This ensures that a GEM handle is created on import and that obj->dma_buf will be set and remain set as long as the object is imported into KFD.

2023-12-13drm/amd/display: For prefetch mode > 0, extend prefetch if possibleAlvin Lee
[Description] For mode programming we want to extend the prefetch as much as possible (up to oto, or as long as we can for equ) if we're not already applying the 60us prefetch requirement. This is to avoid intermittent underflow issues during prefetch. The prefetch extension is applied under the following scenarios: 1. We're in prefetch mode 1 (i.e. we don't support MCLK switch in blank) 2. We're using subvp or drr methods of p-state switch, in which case we we don't care if prefetch takes up more of the blanking time Mode programming typically chooses the smallest prefetch time possible (i.e. highest bandwidth during prefetch) presumably to create margin between p-states / c-states that happen in vblank and prefetch. Therefore we only apply this prefetch extension when p-state in vblank is not required (UCLK p-states take up the most vblank time).

2023-12-12drm/exynos: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2023-12-12drm/exynos: Call drm_atomic_helper_shutdown() at shutdown/unbind timeDouglas Anderson
Based on grepping through the source code this driver appears to be missing a call to drm_atomic_helper_shutdown() at system shutdown time and at driver unbind time. Among other things, this means that if a panel is in use that it won't be cleanly powered off at system shutdown time. The fact that we should call drm_atomic_helper_shutdown() in the case of OS shutdown/restart and at driver remove (or unbind) time comes straight out of the kernel doc "driver instance overview" in drm_drv.c. A few notes about this fix: - When adding drm_atomic_helper_shutdown() to the unbind path, I added it after drm_kms_helper_poll_fini() since that's when other drivers seemed to have it. - Technically with a previous patch, ("drm/atomic-helper: drm_atomic_helper_shutdown(NULL) should be a noop"), we don't actually need to check to see if our "drm" pointer is NULL before calling drm_atomic_helper_shutdown(). We'll leave the "if" test in, though, so that this patch can land without any dependencies. It could potentially be removed later. - This patch also makes sure to set the drvdata to NULL in the case of bind errors to make sure that shutdown can't access freed data.
