[Intel-gfx] [PATCH 0/2] Add support for LMEM PCIe resizable bar

[priyanka.dandamudi]

From: Priyanka Dandamudi <priyanka.dandamudi@intel.com>

Added support to resize the bar to maximum supported,
only when bar is not set to maximum by default.
Also, added new modparam lmem_bar_size which can resize the bar
provided if it is among the supported sizes.

[Intel-gfx] [PATCH 1/2] drm/i915: Add support for LMEM PCIe resizable bar

[priyanka.dandamudi]

From: Akeem G Abodunrin <akeem.g.abodunrin@intel.com>

This patch adds support for the local memory PICe resizable bar, so that
local memory can be resized to the maximum size supported by the device,
and mapped correctly to the PCIe memory bar. It is usual that GPU
devices expose only 256MB BARs primarily to be compatible with 32-bit
systems. So, those devices cannot claim larger memory BAR windows size due
to the system BIOS limitation. With this change, it would be possible to
reprogram the windows of the bridge directly above the requesting device
on the same BAR type.

[Intel-gfx] [PATCH 2/2] drm/i915: Add lmem_bar_size modparam

[priyanka.dandamudi]

From: Priyanka Dandamudi <priyanka.dandamudi@intel.com>

lmem_bar_size is used to resize lmem bar.
It sets to only one of the supported sizes.
Setting this param will be in MB unit.

Maybe add some more information here for why we want to add this?

Something like:

"For testing purposes, support forcing the lmem_bar size through a new 
modparam. In CI we only have a limited number of configurations for DG2, 
but we still need to be reasonably sure we get a usable device (also 
verifying we report the correct values for things like 
probed_cpu_visible_size etc) with all the potential lmem_bar sizes that 
we might expect see in the wild."

This is just a temporary hack until we have all the small-bar stuff 
landed, right? If so, maybe annotate with:

/* XXX: remove once we land small-bar uapi bits */

So we don't forget to remove this.

We don't normally add kernel-doc for static functions.

There are also some checkpatch warnings that need to be fixed, but 
otherwise this looks reasonable to me, and the flow seems to closely 
match what amdgpu is already doing with their bar resizing stuff,
