[igt-dev] [PATCH i-g-t 0/5] IGT bits for small-bar

[Matthew Auld]

small-bar IGT changes for Xe.

[igt-dev] [PATCH i-g-t 1/5] xe: sync small-bar uapi

[Matthew Auld]

We need a couple new fields for the region query and the new flag to
ensure the buffer is CPU accessible.

btw, The kernel patch hasn't been merged into drm-xe yet, are there any 
blockers to merge it?

Hi Matt,

vram_if_possible() uses as the below check routine for vram

uint64_t vram = regions & (~0x1);

but, here uses

uint64_t vram = regions & (0x2 << gt);

Why do you use a different check method than the vram_if_possible()?

Other than that, the rest looks good.

I assume it was just copy-pasted from an earlier version of 
vram_if_possible(). Although I don't quite get why it wants to use 
(~0x1) here, if we are passing in the GT...

It's not directly related to this patch, although I'm just curious 
because I don't know exactly how this test case was added in the first 
place, since the part that comes in as an argument seems to be used to 
calculate the size of the buffer to allocate, and since the mul and div 
variables are not used except to determine the size of the buffer, why 
not just put the value to be multiplied by the buffer directly into the 
section?

rest of changes looks good to me.

Could you use some const or defines instead of this ?
Like SZ_1GB and SZ_4GB ?

imho better:
		bo_flags = visible_vram_if_possible(fd, eci->gt_id);
see below.

Why not move this to bo_flags init above ?

Print the visible size and how much is used. Also sanity check the
values.

If it's not a semantic duplicate check, could you add this sanity check 
as well?
