2021-08-10drm: IRQ midlayer is now legacyThomas Zimmermann
Hide the DRM midlayer behind CONFIG_DRM_LEGACY, make functions use the prefix drm_legacy_, and move declarations to drm_legacy.h. In struct drm_device, move the fields irq and irq_enabled behind CONFIG_DRM_LEGACY. All callers have been updated.

2021-05-10drm: Mark AGP implementation and ioctls as legacyThomas Zimmermann
Only UMs drivers use DRM's core AGP code and ioctls. Mark the icotls as legacy. Add the _legacy_ infix to all AGP functions. Move the declarations to the public and internal legacy header files. The agp field in struct drm_device is now located in the structure's legacy section. Adapt drivers to the changes. AGP code now depends on CONFIG_DRM_LEGACY.

Opencode all macros used from the deprecated drm_os_linux.h header file. The DRM_WAIT_ON used 3 * HZ as timeout. This was translated to 3000 msec.

2012-10-02UAPI: (Scripted) Remove redundant DRM UAPI header #inclusions from drivers/gpu/.David Howells
Remove redundant DRM UAPI header #inclusions from drivers/gpu/. Remove redundant #inclusions of core DRM UAPI headers (drm.h, drm_mode.h and drm_sarea.h). They are now #included via drmP.h and drm_crtc.h via a preceding patch. Without this patch and the patch to make include the UAPI headers from the core headers, after the UAPI split, the DRM C sources cannot find these UAPI headers because the DRM code relies on specific -I flags to make #include "..." work on headers in include/drm/ - but that does not work after the UAPI split without adding more -I flags.

2012-02-16drm: move pci bus master enable into driver.Dave Airlie
The current enabling of bus mastering in the drm midlayer allows a large race condition under kexec. When a kexec'ed kernel re-enables bus mastering for the GPU, previously setup dma blocks may cause writes to random pieces of memory. On radeon the writeback mechanism can cause these sorts of issues. This patch doesn't fix the problem, but it moves the bus master enable under the individual drivers control so they can move enabling it until later in their load cycle and close the race. Fix for radeon kms driver will be in a follow-up patch. Signed-off-by: Dave Airlie <airlied@redhat.com>

2009-03-13drm: Make drm_local_map use a resource_size_t offsetBenjamin Herrenschmidt
This changes drm_local_map to use a resource_size for its "offset" member instead of an unsigned long, thus allowing 32-bit machines with a >32-bit physical address space to be able to store there their register or framebuffer addresses when those are above 4G, such as when using a PCI video card on a recent AMCC 440 SoC. This patch isn't as "trivial" as it sounds: A few functions needed to have some unsigned long/int changed to resource_size_t and a few printk's had to be adjusted. But also, because userspace isn't capable of passing such offsets, I had to modify drm_find_matching_map() to ignore the offset passed in for maps of type _DRM_FRAMEBUFFER or _DRM_REGISTERS. If we ever support multiple _DRM_FRAMEBUFFER or _DRM_REGISTERS maps for a given device, we might have to change that trick, but I don't think that happens on any current driver.

2008-07-14drm: reorganise drm tree to be more future proof.Dave Airlie
With the coming of kernel based modesetting and the memory manager stuff, the everything in one directory approach was getting very ugly and starting to be unmanageable. This restructures the drm along the lines of other kernel components. It creates a drivers/gpu/drm directory and moves the hw drivers into subdirectores. It moves the includes into an include/drm, and sets up the unifdef for the userspace headers we should be exporting. Signed-off-by: Dave Airlie <airlied@redhat.com>
