      drm/radeon/kms: don't require up to 64k allocations. (v2) · 513bcb46
      Dave Airlie authored
      
      
      This avoids needing to do a kmalloc > PAGE_SIZE for the main
      indirect buffer chunk, it adds an accessor for all reads from
      the chunk and caches a single page at a time for subsequent
      reads.
      
      changes since v1:
      Use a two page pool which should be the most common case
      a single packet spanning > PAGE_SIZE will be hit, but I'm
      having trouble seeing anywhere we currently generate anything like that.
      hopefully proper short page copying at end
      added parser_error flag to set deep errors instead of having to test
      every ib value fetch.
      fixed bug in patch that went to list.

      drm/radeon/kms: add r600 KMS support · 3ce0a23d
      Jerome Glisse authored
      
      
      This adds the r600 KMS + CS support to the Linux kernel.
      
      The r600 TTM support is quite basic and still needs more
      work esp around using interrupts, but the polled fencing
      should work okay for now.
      
      Also currently TTM is using memcpy to do VRAM moves,
      the code is here to use a 3D blit to do this, but
      isn't fully debugged yet.

      drm/radeon/kms: add rn50/r100/r200 CS tracker. · 551ebd83
      Dave Airlie authored
      
      
      This adds the command stream checker for the RN50, R100 and R200 cards.
      
      It stops any access to 3D registers on RN50, and does checks
      on buffer sizes on the r100/r200 cards. It also fixes some texture
      sizing checks on r300.

      Fix bandwidth computation and crtc priority in memory controller
      so that crtc memory request are fullfill in time to avoid display

      drm/radeon/kms: add initial colortiling support. · e024e110
      Dave Airlie authored
      
      
      This adds new set/get tiling interfaces where the pitch
      and macro/micro tiling enables can be set. Along with
      a flag to decide if this object should have a surface when mapped.
      
      The only thing we need to allocate with a mapped surface should be
      the frontbuffer. Note rotate scanout shouldn't require one, and
      back/depth shouldn't either, though mesa needs some fixes.
      
      It fixes the TTM interfaces along Thomas's suggestions, and I've tested
      the surface stealing code with two X servers and not seen any lockdep issues.
      
      I've stopped tiling the fbcon frontbuffer, as I don't see there being
      any advantage other than testing, I've left the testing commands in there,
      just flip the fb_tiled to true in radeon_fb.c
      
      Open: Can we integrate endian swapping in with this?
      
      Future features:
      texture tiling - need to relocate texture registers TXOFFSET* with tiling info.
      
      This also merges Michel's cleanup surfaces regs at init time patch
      even though it makes sense on its own, this patch really relies on it.
      
      Some PowerMac firmwares set up a tiling surface at the beginning of VRAM
      which messes us up otherwise.
      that patch is:

      drm/radeon: command stream checker for r3xx-r5xx hardware · 068a117c
      Jerome Glisse authored
      
      
      For security purpose we want to make sure the userspace process doesn't
      access memory beyond buffer it owns. To achieve this we need to check
      states the userspace program. For color buffer and zbuffer we check that
      the clipping register will discard access beyond buffers set as color
      or zbuffer. For vertex buffer we check that no vertex fetch will happen
      beyond buffer end. For texture we check various texture states (number
      of mipmap level, texture size, texture depth, ...) to compute the amount
      of memory the texture fetcher might access.
      
      The command stream checking impact the performances so far quick benchmark
      shows an average of 3% decrease in fps of various applications. It can
      be optimized a bit more by caching result of checking and thus avoid a
      full recheck if no states changed since last check.
      
      Note that this patch is still incomplete on checking side as it doesn't
      check 2d rendering states.

      drm/radeon: introduce kernel modesetting for radeon hardware · 771fe6b9
      Jerome Glisse authored
      
      
      Add kernel modesetting support to radeon driver, use the ttm memory
      manager to manage memory and DRM/GEM to provide userspace API.
      In order to avoid backward compatibility issue and to allow clean
      design and code the radeon kernel modesetting use different code path
      than old radeon/drm driver.
      
      When kernel modesetting is enabled the IOCTL of radeon/drm
      driver are considered as invalid and an error message is printed
      in the log and they return failure.
      
      KMS enabled userspace will use new API to talk with the radeon/drm
      driver. The new API provide functions to create/destroy/share/mmap
      buffer object which are then managed by the kernel memory manager
      (here TTM). In order to submit command to the GPU the userspace
      provide a buffer holding the command stream, along this buffer
      userspace have to provide a list of buffer object used by the
      command stream. The kernel radeon driver will then place buffer
      in GPU accessible memory and will update command stream to reflect
      the position of the different buffers.
      
      The kernel will also perform security check on command stream
      provided by the user, we want to catch and forbid any illegal use
      of the GPU such as DMA into random system memory or into memory
      not owned by the process supplying the command stream. This part
      of the code is still incomplete and this why we propose that patch
      as a staging driver addition, future security might forbid current
      experimental userspace to run.
      
      This code support the following hardware : R1XX,R2XX,R3XX,R4XX,R5XX
      (radeon up to X1950). Works is underway to provide support for R6XX,
      R7XX and newer hardware (radeon from HD2XXX to HD4XXX).
