| * drm: detect hdmi monitor by hdmi identifier (v3)Ma Ling2009-03-29
| | | | | | | | | | | | | | | | Sometime we need to communicate with HDMI monitor by sending audio or video info frame, so we have to know monitor type. However if user utilize HDMI-DVI adapter to connect DVI monitor, hardware detection will incorrectly show the monitor is HDMI. HDMI spec tell us that any device containing IEEE registration Identifier will be treated as HDMI device. The patch intends to detect HDMI monitor by this rule.

| * drm: read EDID extensions from monitorMa Ling2009-03-29
| | | | | | | | | | | | | | | | | | | | | | | | | | Usually drm read basic EDID, that is enough for us, but since igital display were introduced i.e. HDMI monitor, sometime we need to interact with monitor by EDID extension information, EDID extensions include audio/video data block, speaker allocation and vendor specific data blocks. This patch intends to read EDID extensions from digital monitor for users. Signed-off-by: Ma Ling <ling.ma@intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
| * drm: Use a little stash on the stack to avoid kmalloc in most DRM ioctls.Eric Anholt2009-03-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kmalloc was taking up about 1.5% of the CPU on an ioctl-heavy workload (x11perf -aa10text on 965). Initial results look like they have a corresponding improvement in performance for aa10text, but more numbers might not hurt.

| * | drm: Preserve SHMLBA bits in hash key for _DRM_SHM mappings.David Miller2009-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Platforms such as sparc64 have D-cache aliasing issues. We cannot allow virtual mappings in different contexts to be such that two cache lines can be loaded for the same backing data. Updates to one cache line won't be seen by accesses to the other cache line. Code in sparc64 and other architectures solve this problem by making sure that all userland mappings of MAP_SHARED objects have the same virtual address base. They implement this by keying off of the page offset, and using that to choose a suitably consistent virtual address for mmap() requests. Making things even worse, getting this wrong on sparc64 can result in hangs during DRM lock acquisition. This is because, at least on UltraSPARC-III, normal loads consult the D-cache but atomics such as 'cas' (which is what cmpxchg() is implement using) only consult the L2 cache. So if a D-cache alias is inserted, the load can see different data than the atomic, and we'll loop forever because the atomic compare-and-exchange will never complete successfully. So to make this all work properly, we need to make sure that the hash address computed by drm_map_handle() preserves the SHMLBA relevant bits, and that's what this patch does for _DRM_SHM mappings. As a historical note, many years ago this bug didn't exist because we used to just use the low 32-bits of the address as the hash and just hope for the best. This preserved the SHMLBA bits properly. But when the hashtab code was added to DRM, this was no longer the case. Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Dave Airlie <airlied@redhat.com>

However, the code unconditionally uses DRM_{READ,WRITE}32() (and thus readl() and writel()) to access it. Basically, if RADEON_IS_AGP then it's ioremap()'d memory else it's vmalloc'd memory. Adjust all of the ring_rptr access code as needed. While we're here, kill the 'scratch' pointer in drm_radeon_private. It's only used in the one place where it is initialized. Signed-off-by: David S.

But it could be in the framebuffer, for example, and thus we're dealing with a PCI MEM space ioremap() cookie.

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.

For some reasons, while the BSD port still has that "feature", the linux part abused drm_map for kernel internal usage as the local map only existed as a typedef of the struct drm_map. This patch fixes it by declaring struct drm_local_map separately (though its content is currently identical to the userspace variant), and changing the kernel code to only use that, except when it's a user<->kernel interface (ie. ioctl). This allows subsequent changes to the in-kernel format I've also replaced the use of drm_local_map_t with struct drm_local_map in a couple of places. Mostly by accident but they are the same (the former is a typedef of the later) and I have some remote plans and half finished patch to completely kill the drm_local_map_t typedef so I left those bits in.

| * | drm: Use resource_size_t for drm_get_resource_{start, len}Benjamin Herrenschmidt2009-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DRM uses its own wrappers to obtain resources from PCI devices, which currently convert the resource_size_t into an unsigned long. This is broken on 32-bit platforms with >32-bit physical address space. This fixes them, along with a few occurences of unsigned long used to store such a resource in drivers.
