drm/amd/display: expose additional modifier for DCN32/321

2022-06-29T21:12:18+00:00

[Why&How] Some userspace expect a backwards compatible modifier on DCN32/321. For hardware with num_pipes more than 16, we expose the most efficient modifier first. As a fall back method, we need to expose slightly inefficient modifier AMD_FMT_MOD_TILE_GFX9_64K_R_X after the best option. Also set the number of packers to fixed value as required per hardware documentation. This value is cached during hardware initialization and can be read through the base driver.

drm/amd: Add GFX11 modifiers support to AMDGPU (v3)

2022-06-03T20:43:38+00:00

GFX11 IP introduces new tiling mode. Various combinations of DCC settings are possible and the most preferred settings must be exposed for optimal use of the hardware. add_gfx11_modifiers() is based on recommendation from Marek for the preferred tiling modifier that are most efficient for the hardware. v2: microtiling fix noticed by Marek v3: keep Z tiling check Signed-off-by: Aurabindo Pillai Acked-by: Alex Deucher Signed-off-by: Alex Deucher

dma-buf: add enum dma_resv_usage v4

2022-04-07T10:53:53+00:00

This change adds the dma_resv_usage enum and allows us to specify why a dma_resv object is queried for its containing fences. Additional to that a dma_resv_usage_rw() helper function is added to aid retrieving the fences for a read or write userspace submission. This is then deployed to the different query functions of the dma_resv object and all of their users. When the write paratermer was previously true we now use DMA_RESV_USAGE_WRITE and DMA_RESV_USAGE_READ otherwise. v2: add KERNEL/OTHER in separate patch v3: some kerneldoc suggestions by Daniel v4: some more kerneldoc suggestions by Daniel, fix missing cases lost in the rebase pointed out by Bas.
