Xe driver currently supports 22-bit addresses for MMIO access. Future platforms will have additional MMIO extension with larger address spaces, and to access them, the driver will have to support wider address representation. Please note that while the XE_REG macro is used for MMIO access, XE_REG_EXT macro will be used for MMIO-extension access. Signed-off-by:

In a future patch userspace will be able to directly set the pat_index as part of vm_bind. To support this we need to get away from using xe_cache_level in the low level routines and rather just use the pat_index directly. v2: Rebase v3: Some missed conversions, also prefer tile_to_xe() (Niranjana) v4: remove leftover const (Lucas) Signed-off-by:

We don't seem to use the 4-7 pat indexes, even though they are defined by the HW. In a future patch userspace will be able to directly set the pat_index as part of vm_bind and we don't want to allow setting 4-7. Simplest is to just ignore them here. Suggested-by:

The PAT tables become significantly more complicated on Xe2 platforms. They now control L3, L4, and coherency settings, as well as additional characteristics such as compression. Aside from the main PAT table, there's an additional register that also needs to be programmed with PAT settings for PCI Address Translation Services. Bspec: 71582 Signed-off-by:

It doesn't look like you can mix and match devm_ and drmmm_ for a managed resource. For drmmm the resources are all tracked in drm with its own list, and there is only one devm_ resource for the entire list. If the driver itself also adds some of its own devm resources, then those will be released first. In the case of hwmon the devm_kzalloc will be freed before the drmmm_ action to destroy the mutex allocated within, leading to uaf. Since hwmon itself wants to use devm, rather use that for the mutex destroy. Closes: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/766Signed-off-by:

Xe2 changes or adds bits for mocs in a few BLT instructions: XY_CTRL_SURF_COPY_BLT, XY_FAST_COLOR_BLT, XY_FAST_COPY_BLT, and MEM_SET. Modify the code to deal with the new location. Unlike Xe1, the MOCS field in those instructions is only the MOCS index and not the Structure_MEMORY_OBJECT_CONTROL_STATE anymore. The pxp bit is now explicitly documented separately.

Set bits 30 and 31 of XY_FAST_COPY_BLT's dword1 for XeHP and above. Destination or source being Y-Major is selected on dword0 and there's nothing to set on dword1. According to the bspec for Xe2, "Behavior is undefined when programmed the value 0". Also for XeHP, the only value allowed in those bits is 0b11, not being possible to select "Legacy Tile-Y" anymore, only the newer Tile4. So, unconditionally set those bits for graphics IP 12.50 and above. v2: Reword commit message and extend it to graphics version >= 12.50 (Matt Roper) Bspec: 57567 Cc: Matt Roper <matthew.d.roper@intel.com> Signed-off-by: -

In xe_wait_user_fence_ioctl, the timeout is currently defined as unsigned long. That could potentially pass a negative value to the schedule_timeout() call because nsecs_to_jiffies() returns an unsigned long which gets used as signed long.
