The platforms that support the interrupt from the I2C
adapter can not handle the amount of interrupts the adapter
generates because of the way the IRQ is routed in the
hardware. The I2C controller driver has to be kept in
polling mode because of that.
The AMC MCU can still generate critical alerts that have to
be handled. The interrupt from SMBus Alert is left enabled
and handled separately in the Xe. The alerts from the AMC
will cause the device to be declared wedged for now.

Add error_detected, mmio_enabled, slot_reset and resume recovery callbacks
to handle PCIe Advanced Error Reporting (AER) errors.
For fatal errors, the device is wedged and becomes inaccessible. Return
PCI_ERS_RESULT_NEED_RESET from error_detected to request a Secondary
Bus Reset (SBR).
For non-fatal errors, return PCI_ERS_RESULT_CAN_RECOVER from
error_detected to trigger the mmio_enabled callback. In this callback, the
device is queried to determine the error cause and attempt recovery based
on the error type.
Once the secondary bus reset(SBR) is completed the slot_reset callback
cleanly removes and reprobe the device to restore functionality.

When building with 'make M=drivers/gpu/drm/xe modules', kbuild invokes
scripts/Makefile.build with obj=., causing $(obj) to expand to '.'.
Make normalizes './xe_gen_wa_oob' to 'xe_gen_wa_oob' when constructing
the $^ automatic variable (target name normalization), so the recipe
command becomes just 'xe_gen_wa_oob ...' without any path prefix, and
the shell cannot find the tool.
Fix by replacing $^ with explicit $(obj)/xe_gen_wa_oob and
$(src)/<rules-file> references in both wa_oob recipe commands.
In recipe strings, make does not apply target name normalization, so
$(obj)/xe_gen_wa_oob correctly expands to './xe_gen_wa_oob' and the
shell can execute it. This matches the pattern already used by other
DRM drivers (e.g. radeon's mkregtable).

MCHBAR registers are a bit special in that:
- we access them through the mirror
- the mirror is read only on HSW+
- the mirror requires the actual MCHBAR to be enabled in device 0:0.0
- the mirror is gone on MTL+
So I'd prefer to treat MCHBAR registers as a bit special in

intel_mchbar_read*().

Page reclaim list (PRL) is preparation work for the page reclaim feature.
The PRL is firstly owned by pt_update_ops and all other page reclaim
operations will point back to this PRL. PRL generates its entries during
the unbind page walker, updating the PRL.
This PRL is restricted to a 4K page, so 512 page entries at most.
v2:
- Removed unused function. (Shuicheng)
- Compacted warning checking, update commit message,
spelling, etc. (Shuicheng, Matthew B)
- Fix kernel docs
- Moved PRL max entries overflow handling out from
generate_reclaim_entry to caller (Shuicheng)
- Add xe_page_reclaim_list_init for clarity. (Matthew B)
- Modify xe_guc_page_reclaim_entry to use macros
for greater flexbility. (Matthew B)
- Add fallback for PTE outside of page reclaim supported
4K, 64K, 2M pages (Matthew B)
- Invalidate PRL for early abort page walk.
- Removed page reclaim related variables from tlb fence
(Matthew Brost)
- Remove error handling in *alloc_entries failure. (Matthew B)
v3:
- Fix NULL pointer dereference check.
- Modify reclaim_entry to QW and bitfields accordingly. (Matthew B)
- Add vm_dbg prints for PRL generation and invalidation. (Matthew B)
v4:
- s/GENMASK/GENMASK_ULL && s/BIT/BIT_ULL (CI)
v5:
- Addition of xe_page_reclaim_list_is_new() to avoid continuous
allocation of PRL if consecutive VMAs cause a PRL invalidation.
- Add xe_page_reclaim_list_valid() helpers for clarity. (Matthew B)
- Move xe_page_reclaim_list_entries_put in
xe_page_reclaim_list_invalidate.
