Two parts to this, one is simple unplug from sysfs for the device node. The second adds an unplugged state, if we have device opens, we just set the unplugged state and return, if we have no device opens we drop the drm device. If after a lastclose we discover we are unplugged we then drop the drm device. v2: use an atomic for unplugged and wrap it for users, add checks on open + mmap + ioctl entry points.

Talking to Al Viro on irc, we can see no possible reason for doing this, the upper mmap code does it. The code has been there since first import into drm tree I can find.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

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.

Once upon a time, the DRM made the distinction between the drm_map data structure exchanged with user space and the drm_local_map used in the kernel. 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.

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: NDave Airlie <airlied@redhat.com>

This patch fixes bits of the DRM so to make the radeon DRI work on non-cache coherent PCI DMA variants of the PowerPC processors.

As a fallout, replace filp storage with file_priv storage for "unique identifier of a client" all over the DRM. There is a 1:1 mapping, so this should be a noop. This could be a minor performance improvement, as everyth on Linux dereferenced filp to get file_priv anyway, while only the mmap ioct went the other direction.
