[Intel-gfx] [PATCH i-g-t v6 00/21] Implement sw_sync test

[robert.foss at collabora.com]

From: Robert Foss <robert.foss at collabora.com>

This series implements the sw_sync test and the lib/sw_sync helper functions for said test.

The sw_sync subtests range from very basic tests of the sw_sync functionality, to stress testing and randomized tests.


Changes since v1:
Added "Reviewed-by: Eric Engestrom <eric at engestrom.ch>" tag

  lib/sw_sync:
  - Fixed fd value checking
  - Fixed fd validity check in sw_sync_fd_close()
  - Moved sw_sync related paths to define
  - Switched from malloc+memset to calloc in sync_file_info()
  - Switched sizeof to dereferenced ptr

  tests/sw_sync:
  - Moved lib/sw_sync related code to lib/sw_sync commit
  - Replaced memset with assignment in loop


Changes since v2:

  lib/sw_sync:
  - Replaced fd validity check in sw_sync_timeline_create()
  - Replace sw_sync_XXX_destroy() functions with close()
  - Simplified sw_sync_timeline_inc() comparison
  - Changed sw_sync_merge() return value to -errno
  - Changed name of sw_sync_fence_size() to sw_sync_fence_count()
  - Reworked implementation of sw_sync_fence_count()
  - Reworked implementation of sw_sync_fence_count_status()

  tests/sw_sync:
  - Replace sw_sync_XXX_destroy() functions with close()


Changes since v3:

  lib/sw_sync:
  - Changed sw_sync_fence_create() to take uint32_t seqno
  - Added raw __sw_sync_fence_create() and failure check sw_sync_fence_create()

  tests/sw_sync:
  - Switch to using __sw_sync_fence_create() for failure cases


Changes since v4:

  lib/sw_sync:
  - Fixed whitespace in sw_sync_fence_count()
  - Fixed whitespace and style of sw_sync_wait()
  - Fixed whitespace in __sw_sync_fence_count_status()


Changes since v5:

  lib/sw_sync:
  - Added kernel_has_sw_sync()
  - Added igt_require_sw_sync()
  - Split out __sw_sync_merge() from sw_sync_merge()
  - Added igt_debugfs.h include
  - Change sw_sync_wait to reflect android implementation
  - Renamed some functions:
   - sw_sync_merge -> sync_merge
   - sw_sync_wait -> sync_wait
   - sw_sync_fence_count -> sync_fence_count
   - sw_sync_fence_count_status -> sync_fence_count_status
   - __sw_sync_fence_count_status -> __sync_fence_count_status

  tests/sw_sync:
  - Added subtest test_sync_expired_merge
  - Added subtest test_timeline_closed
  - Added subtest test_timeline_closed_signaled
  - Added subtest test_sync_merge_invalid
  - Added subtest test_sync_busy_fork
  - Added subtest test_sync_busy_unixsockets
  - Skip test on no sw_sync support
  - Reworked comments of test_sync_wait
  - Renamed test_sync_wait -> test_sync_busy
  - Improved test_sync_wait igt_assert_f messages
