<content type='text'>
commit eb0d253ff9c74dee30aa92fe460b825eb28acd73 upstream.

There is no point in requesting 1 tile on VPU40xx as the FW will
probably need more tiles to run workloads, so it will have to
reconfigure PLL anyway. Don't enable any tiles and allow the FW to
perform initial tile configuration.

This improves NPU boot stability as the tiles are always enabled only
by the FW from the same initial state.

Set AW_SNOOP_OVERRIDE bit in VPU_37/40XX_HOST_IF_TCU_PTW_OVERRIDES
to force snooping for MMU write accesses (setting event queue events).

MMU event queue buffer is the only buffer written by MMU and
mapped as write-back which break cache coherency. Force write
transactions to be snooped solving the problem.

<content type='text'>
Using PCI Device ID/Revision to initialize the interrupt_clear_with_0
workaround is problematic - there are many pre-production
steppings with different behavior, even with the same PCI ID/Revision

Instead of checking for PCI Device ID/Revision, check the VPU
buttress interrupt status register behavior - if this register
is not zero after writing 1s it means there register is RW
instead of RW1C and we need to enable the interrupt_clear_with_0
workaround.

<id>urn:sha1:3f7c0634926daf48cd2f6db6c1197a1047074088</id>
<content type='text'>
There is no need to call MMIO reset using VPU_37XX_BUTTRESS_VPU_IP_RESET
register. IP will be reset by FLR or by entering d0i3. Also IP reset
during power_up is not needed as the VPU is already in reset.

Removing MMIO reset improves stability as it a partial device reset
that is not safe in some corner cases.

This change also brings back ivpu_boot_pwr_domain_disable() that
helps to properly power down VPU when it is hung by a buggy workload.

The usage count of struct dev_pm_info is an implementation detail that
is only available if CONFIG_PM is enabled, so printing it in a debug message
causes a build failure in configurations without PM:

  and there's little I can say which isn't in the individual changelogs.

  The lengthier patch series are

   - 'kdump: use generic functions to simplify crashkernel reservation
     in arch', from Baoquan He. This is mainly cleanups and
     consolidation of the 'crashkernel=' kernel parameter handling

   - After much discussion, David Laight's 'minmax: Relax type checks in
     min() and max()' is here. Hopefully reduces some typecasting and
     the use of min_t() and max_t()

   - A group of patches from Oleg Nesterov which clean up and slightly
