      Tejun Heo 提交于
      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.

      drm: Convert proc files to seq_file and introduce debugfs · 955b12de
      Ben Gamari 提交于
      The old mechanism to formatting proc files is extremely ugly. The
      seq_file API was designed specifically for cases like this and greatly
      simplifies the process.
      
      Also, most of the files in /proc really don't belong there. This patch
      introduces the infrastructure for putting these into debugfs and exposes
      all of the proc files in debugfs as well.
      
      This contains the i915 hooks rewrite as well, to make bisectability better.

      drm: Make drm_local_map use a resource_size_t offset · 41c2e75e
      Benjamin Herrenschmidt 提交于
      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.

      drm: Split drm_map and drm_local_map · f77d390c
      Benjamin Herrenschmidt 提交于
      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.

      drm: Add GEM ("graphics execution manager") to i915 driver. · 673a394b
      Eric Anholt 提交于
      GEM allows the creation of persistent buffer objects accessible by the
      graphics device through new ioctls for managing execution of commands on the
      device.  The userland API is almost entirely driver-specific to ensure that
      any driver building on this model can easily map the interface to individual
      driver requirements.
      
      GEM is used by the 2d driver for managing its internal state allocations and
      will be used for pixmap storage to reduce memory consumption and enable
      zero-copy GLX_EXT_texture_from_pixmap, and in the 3d driver is used to enable
      GL_EXT_framebuffer_object and GL_ARB_pixel_buffer_object.

      drm: reorganise drm tree to be more future proof. · c0e09200
      Dave Airlie 提交于
      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.

      I also tried more carefully to avoid problems with the same token
