[igt-dev] [PATCH i-g-t v4 0/6] Compression support for Lunarlake

[Akshata Jahagirdar <akshata.jahagirdar@intel.com>]

Series enables the compression feature for Lunarlake and address various
changes of the feature from Gen12. The Main-to-CCS ratio has been
changed to 512:1. This changes the calculations and value for fields
such as CCS Copy size for blitter command APIs. 
This patch series updates tests xe_ccs and gem_ccs for XE2.  

These changes are based on top of the "vm_bind pat_index" patch here:
https://patchwork.freedesktop.org/series/124667/

v2: Lots of improvements/tweaks (Kamil)
    Addressed review comments (Matthew, Karolina)
v3: Reused dg2_xy_fast_copy definition for defing xe2_cmds_info struct(Karolina)
    Split the patch to address ccs_size calculation and updating
pat_index, updated the intel_get_pat_idx_uc_comp function as per review
comments (Kamil)
v4: Addressed review comments (Karolina)
    Rebase. Removed few unnecessary conditions, plus few fixes.
