Simon Ser	4f06ce2550	render/gbm_allocator: avoid drmPrimeHandleToFD ... Some drivers (e.g. nouveau) need to do some book-keeping when exporting a BO handle to a DMA-BUF [1]. Using drmPrimeHandleToFD directly hides the export from the user-space drivers and causes some ref'counting issues. So we can't properly handle BOs with a different handle for each plane until [2] lands.

Simon Ser	bf86110fc5	render/gbm_allocator: set modifier to INVALID if implicit ... When gbm_bo_create is used and the GBM implementation does support modifiers, gbm_bo_get_modifier may return something other than DRM_FORMAT_MOD_INVALID. This can cause issues with the rest of the stack (e.g. EGL or KMS) in case these don't support modifiers. Instead, force the modifier to INVALID, to make sure no one uses modifiers.	4 years ago
Simon Ser	b5cefada92	render/gbm_allocator: export to DMA-BUF on init ... Instead of lazily exporting BOs to DMA-BUFs, do it on init. This is the only way to use the buffer, so there's no point in deferring that work. This is preparatory work for the next commit.	4 years ago
