* [igt-dev] [CI i-g-t] lib/ioctl_wrappers: Handle PREAD/PWRITE ioctls not supported in gem_read/write
@ 2021-03-15 21:16 Ashutosh Dixit
  0 siblings, 0 replies; 16+ messages in thread
From: Ashutosh Dixit @ 2021-03-15 21:16 UTC (permalink / raw)
  To: igt-dev

FOR CI ONLY. PLEASE DON'T REVIEW.

Trial patch to replace PREAD/PWRITE ioctls with mmap + memcpy in gem_read/write.

v11: Simplified patch to use previous __gem_read/__gem_write
v12: Fix CI failures in gem_madvise and gen9_exec_parse
v13: Skip mmap for 0 length read/write's
v14: Rebase on latest master, remove redundant asserts/checks in mmap_read/write
v15: Fix CI failures in gem_exec_parallel@userptr
v16: rebase, gem_exec_parallel@userptr no longer does a gem_read

* [igt-dev] [CI i-g-t] lib/ioctl_wrappers: Handle PREAD/PWRITE ioctls not supported in gem_read/write
@ 2021-01-21  5:52 Ashutosh Dixit
  0 siblings, 0 replies; 16+ messages in thread
From: Ashutosh Dixit @ 2021-01-21  5:52 UTC (permalink / raw)

FOR CI ONLY. PLEASE DON'T REVIEW.

Trial patch to replace PREAD/PWRITE ioctls with mmap + memcpy in gem_read/write.

v11: Simplified patch to use previous __gem_read/__gem_write
v12: Fix CI failures in gem_madvise and gen9_exec_parse
v13: Skip mmap for 0 length read/write's
v14: Rebase on latest master, remove redundant asserts/checks in mmap_read/write
v15: Fix CI failures in gem_exec_parallel@userptr

* [igt-dev] [CI i-g-t] lib/ioctl_wrappers: Handle PREAD/PWRITE ioctls not supported in gem_read/write
@ 2020-09-06 23:36 Ashutosh Dixit
  0 siblings, 0 replies; 16+ messages in thread
From: Ashutosh Dixit @ 2020-09-06 23:36 UTC (permalink / raw)
  To: igt-dev

FOR CI ONLY. PLEASE DON'T REVIEW.

Trial patch to replace PREAD/PWRITE ioctls with mmap + memcpy in gem_read/write.

v11: Simplified patch to use previous __gem_read/__gem_write
v12: Fix CI failures in gem_madvise and gen9_exec_parse
v13: Skip mmap for 0 length read/write's

* [igt-dev] [CI i-g-t] lib/ioctl_wrappers: Handle PREAD/PWRITE ioctls not supported in gem_read/write
@ 2020-09-01 18:18 Ashutosh Dixit
  0 siblings, 0 replies; 16+ messages in thread
From: Ashutosh Dixit @ 2020-09-01 18:18 UTC (permalink / raw)
  To: igt-dev

FOR CI ONLY. PLEASE DON'T REVIEW.

Trial patch to replace PREAD/PWRITE ioctls with mmap + memcpy in gem_read/write.
