Subject: [PATCH i-g-t v4 00/13] Implement sw_sync test
Date: Wed, 14 Sep 2016 11:04:29 -0400	[thread overview]
Message-ID: <20160914150442.18183-1-robert.foss@collabora.com> (raw)

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

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

Gustavo Padovans sw_sync series was just de-staged in
gregkh-staging/staging-next [1], and this test is targeted at verifying the
functionality implemented in that series.

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@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
