> Subject: [PATCH V3 0/3] drm/xe: Add sysfs entry for tile and relate it to GTs
> 
> With the separation of xe_tile and xe_gt, We now consider a PCI device
> (xe_device) to contain one or more tiles (struct xe_tile).
> Each tile will contain one or two GTs (struct xe_gt).
> 
> Sysfs entries also needs to be aligned as follows:
> 
> drm/xe: Add sysfs entry per tile - Adds tile sysfs infrastructure
> drm/xe: Add GTs under respective tile sysfs - Relates GTs to each tile sysfs
> drm/xe: Add sysfs entry to report per tile memory size - Reports actual
> physical memory per respective tile
> 
> Sysfs entries will be as follows:
> cat /sys/class/drm/card1/device/tileN/addr_range
> 
> V3 :
>    - Make tile_sysfs_init return void and warn for errors
>    - Exclude DG1 as it does not have TILE_ADDR_RANGE reg
>    - Use sysfs_create_files -> sysfs_create_file
> V2 :
>    - Address review comments
