[igt-dev] [PATCH i-g-t v3 1/4] lib/ioctl_wrapper: use defines for get_param instead of param number

[igt-dev] [PATCH i-g-t v3 1/4] lib/ioctl_wrapper: use defines for get_param instead of param number

[Lukasz Kalamarz]

In lib code there were few functions using param number instead of
defines. This could lead to some issues (i.e. stolen support
pointing on different parameter) and we would like to avoid them.
v2: Rebased patch

[igt-dev] [PATCH i-g-t v3 2/4] lib/igt_dummyload: use gem_mmap__cpu and gem_mmap__wc when applicable

[Lukasz Kalamarz]

We had some duplicates in code that are using direct call to
__gem_mmap__cpu or __gem_mmap__wc and then assert it result, which is what
gem_mmap__cpu and gem_mmap__wc is taking care for us.
v2: Rebased and reordered this patch in series

[igt-dev] [PATCH i-g-t v3 3/4] lib/ioctl_wrapper: Implement __gem_mmap

[Lukasz Kalamarz]

Previous implementation of __gem_mmap__cpu and __gem_mmap_wc only
differ with setting proper flag for caching. This patch implement
__gem_mmap, which merge those two functions into one.
v2: Reordered and splited this patch into two separete patches
v3: Dropped unnecessary check

[igt-dev] [PATCH i-g-t v3 4/4] lib/ioctl_wrapper: Use __gem_mmap within __gem_mmap__cpu/wc

[Lukasz Kalamarz]

This patch remove duplicated code from __gem_mmap__cpu/wc functions
and instead use call to __gem_mmap function, which is doing exactly
the same work.

I think it make more sense for this to be a single patch together with 
the next one. Easier to review as well.

This is a bit unclear IMO, as it sounds like the bypassing the GPU is 
only valid for wc == false, which isn't true since WC also bypasses the 
gpu caches.

Also, instead of using wc == true/false I would say "wc mmappings" and 
"!wc mmappings" or something like that.

The 3 defines you're touching are part of the published kernel uapi, so 
there is no way for them to change and cause issues. The change is still 
worth doing IMO since defines are better than hard-coded numbers.

All 3 defs are in the i915_drm.h file in IGT, so with a cleaned commit 
message:

In theory what You've said is true, but we had one example within IGT
that may be causing troubles. We had gem_stolen issue, where we are
pointing to param with direct number (38), but then uapi is pointing on
something different (changes in i915 for stole support were never
merged). When running those tests (only hibernate testcase is not run
in during fullrun executions) we may be touching something different
than we expect.

Will change wording in description. My thought was that word 'also' in
second sentence will connect those two for a case, when wc == true.

My comment was regarding exclusively the flags touched by this patch. 
The test in your example was merged to IGT before the flag was merged in 
the kernel, which meant the latter was still not part of the uapi and 
thus could still change.
