How many times do I have to say that I am sorry for introducing static
here. It was to cut down on strace spam, but no one should be repeatedly
checking, so please don't cargo cult it. It doesn't bode well.

What's wrong with this optimization technique? Is that possible for single
i915 driver we got different results? Only reason I see would be to have
two different GPU's with different generations, but it is impossible?

This is duplicated at gem_mmap_offset__has_wc()
This logic shouldn't be needed either, if we have mmap_offset, we'll
have WC support. What this logic checks is if default placed object will
support WC mmap, which is very different from what this function
originally did.

Ditto, shouldn't be needed ever.

Again, there is code duplication below (__gem_mmap_offset__wc).
> + else
> + return __gem_mmap(fd, handle, offset, size, prot, I915_MMAP_WC);
The naming also gets confusing when we have nesting multiplexers.
I would assume us to want to flatten the code:
if (has_mmap_offset())
return __gem_mmap_offset__wc()
else
return __gem_mmap_gtt__wc()
That probably requires some renames.

Fwiw, that's not always true. Once you know which ioctl you have,
you need to query the WC flags to verify the processor supports WC
access. With Xen even recent processors may be lacking a few essentials.

LMEM series introduced concept of memory_regions. This patch implement
helper functions that allow user to manage them in more convenient way.

We should be just fine requesting the minimum BO size we need, letting the KMD
round the sizes up and reading back the created BO size.
(Now that the regression has been fixed, too :) )
So the code logic needs to be updated to follow that.

On a second thought we may be better off rounding the backing storage
size up transparently.
I guess the prime question is why would the userspace/IGT care for
actual backing storage size?
Abdiel/Matt, how painful would it be to round the backing storage size
up, irrespective of the BO size?

I think this function should be called a little bit different, likely:
bool gem_is_memory_region_exist(...) or sth.
Your name suggest you'll return some region, not bool.

This test is a copy/paste of few gem_mmap subtests, due to good
coverage in previous one. We also need to be sure that we cover
all available memory regions.

As a part of local memory effort we need to make sure, that basic
scenarios are covered for every available memory region. This patch is
an attempt for this problem. If it will be accepted it will be
replicated on each test that can benefit from it.

Summary
-------
**FAILURE**
Serious unknown changes coming with IGTPW_3346 absolutely need to be
verified manually.
If you think the reported changes have nothing to do with the changes
introduced in IGTPW_3346, please notify your bug team to allow them
to document this new failure mode, which will reduce false positives in CI.
