With CONFIG_SMP=n and CONFIG_DEBUG_SPINLOCK=y the vmwgfx kernel module would unconditionally throw a bug when checking for a held spinlock in the command buffer code. Fix this by using a lockdep check. Cc: <stable@vger.kernel.org> Reported-and-tested-by:

The new debugfs initialization code fails to build when CONFIG_DEBUG_FS is disabled: In file included from /git/arm-soc/drivers/gpu/drm/nouveau/nouveau_drm.c:57:0: drivers/gpu/drm/nouveau/nouveau_debugfs.h: In function 'nouveau_debugfs_init': drivers/gpu/drm/nouveau/nouveau_debugfs.h:37:29: error: parameter name omitted nouveau_debugfs_init(struct nouveau_drm *) This fixes the prototypes so we can build it again.

Most VM BOs end up in the duplicates list, validate it first make -ENOMEM less likely. Signed-off-by:

This makes it less likely to run into an ENOMEM because VM page tables are evicted last. v2: move the BOs in the LRU tail after validation Signed-off-by:

Christian König authored
This allows the drivers to move a BO to the end of the LRU without removing and adding it again. v2: Make it more robust, handle pinned and swapable BOs as well. Reviewed-by:

Christian König authored
It doesn't make any sense to try to swap out imported BOs. Reviewed-by:
-
Christian König authored
If we import a BO with an external reservation object we don't reserve/unreserve it. So we never add it to the LRU causing a possible denial of service. v2: fix typo in commit message Reviewed-by:

Hardware blocks on the GPU like ACP generate interrupts in the GPU interrupt controller, but are driven by a separate driver. Add an irq domain to the GPU driver so that blocks like ACP can register a Linux interrupt. Acked-by:

This provides an interface to get access to the base address of PCI resources (MMIO, DOORBELL, etc.). Only MMIO and DOORBELL are implemented right now. This is necessary to properly utilize shared drivers on platform devices. IP modules can use this interface to get the base address of the resource and add any additional offset and set the size when setting up the platform driver(s). Acked-by:
