[Mesa-dev] [PATCH V2 00/17] Newbie Project : Enable ARB_map_buffer_alignment in all drivers

[Siavash Eliasi]

Hello, this is V2 series of patches to accomplish *Enable ARB_map_buffer_alignment in all drivers* newbie project suggested by Ian Romanick.

Revision 2:
- Fixed setting switch cases prior to PIPE_CAP_MIN_MAP_BUFFER_ALIGNMENT incorrectly.
- Fixed memory leak.


Best regards,
Siavash Eliasi.

Siavash Eliasi (17):
  softpipe: Modified allocation routine to use alignment of 64 instead
    of 16.
  softpipe: Modified softpipe to return 64 in case of
    PIPE_CAP_MIN_MAP_BUFFER_ALIGNMENT.
  llvmpipe: Modified allocation routines to use alignment of 64 instead
    of 16.
  llvmpipe: Modified llvmpipe to return 64 in case of
    PIPE_CAP_MIN_MAP_BUFFER_ALIGNMENT.
  i915: Modified i915_buffer_create to use memory allocation alignment
    of 64 instead of 16.
  i915: Modified i915g to return 64 in case of
    PIPE_CAP_MIN_MAP_BUFFER_ALIGNMENT.
  svga: Modified svga to return 64 in case of
    PIPE_CAP_MIN_MAP_BUFFER_ALIGNMENT.
  ilo: Modified ilo to return 4096 in case of
    PIPE_CAP_MIN_MAP_BUFFER_ALIGNMENT.
  mesa: Modified Mesa state tracker to unconditionally enable
    ARB_map_buffer_alignment.
  mesa: Modified _mesa_init_constants to set
    ctx->Const.MinMapBufferAlignment to 64.
  mesa: Modified _mesa_buffer_data to use _mesa_align_malloc.
  radeon: Modified radeonBufferData to pass
    ctx->Const.MinMapBufferAlignment as the alignment value to
    radeon_bo_open.
  nouveau: Modified nouveau_bufferobj_data to pass
    ctx->Const.MinMapBufferAlignment as the alignment value to
    nouveau_bo_new.
  i915: Modified i915 intel_bufferobj_data to use _mesa_align_malloc
    instead of malloc.
  i965: Modified brw_initialize_context_constants to set
    ctx->Const.MinMapBufferAlignment to 4096.
  mesa: Modified extensions table to use o(dummy_true) instead of
    o(ARB_map_buffer_alignment).
  mesa: Deleted gl_extensions::ARB_map_buffer_alignment and all of its
    use cases.
