Would be nice to test on ThunderX2 :)

Does not attach on ThunderX2 (no sbsawdt0 in dmesg).

oh.. https://www.mail-archive.com/kernel-packages@lists.launchpad.net/msg272248.html

I guess we don't have any more platforms to test..

arm64 acpi_iort: add some error handling

arm64 gicv3_its: enable all ITS blocks for a CPU

arm64 gic: Drop unused GICV3_IVAR_REDIST_VADDR

address andrew's comment.

Fix the check for warning (i > 1 now), fix up error message, and add a comment.

I took a second look at this, and ran some more testing. I need to fix up a bug and add more comments.

How frequently is srat_resolve_its_pxm called?

arm64 gicv3_its: Fix a typo

gic_v3: consolidate per-cpu redistributor information

fixes for addressing andrew's not on KABI.

arm64 nexus: remove incorrect warning

Let me know if you need a new rev with bool.

Tested with overnight 'make -j 224 buildworld' without failures.

How long does that take?

This fixes the failure on ThunderX2 when INVARIANTS are turned off. The failure was:

pci_host_generic_acpi: use IORT data for MSI/MSI-X

arm64 gicv3: add IORT and NUMA support

arm64 acpi: Add support for IORT table

Will rebase and submit a new rev addressing the comment.

arm, acpi: increase size of memory region arrays

Dropping this for now. We need better EARLY_PRINTF support like andrew noted above before adding this.

On second thought, for now I think I will drop this until we have a better EARLY_PRINTF

arm64: add ACPI based NUMA support

acpica: support parsing of arm64 affinity in acpi_pxm.c

acpica : move SRAT/SLIT parsing to sys/dev/acpica

x86/acpica/srat.c: Add API for parsing proximity tables

markj: Regarding the question on pxm prefix. I used the convention starting with the filename. I kind of settled for acpi_pxm since I could not think of a better filename and prefix (which covers SRAT for resource affinity and SLIT for locality).

markj: please see the inline comment, and let me know if think there is further changes needed. Thanks.

Few fixes to earlier revision-

IORT table walking fixed (not to use acpi_walk_subtables since the header is slightly different)
proximity is changed to int, so that we can return -1 when SRAT does not have an entry.
return o copy data is changed to void since it returned only 0 - this simplified the code a bit.

New version planned with correct way of walking IORT.

gitv3_its: fixes for multiple GIC ITS blocks

pci_host_generic : move activate/release to generic code

pci_host_generic, acpi_resource: drop unneeded code

acpica, pci_host_generic_acpi: redo pci_host_generic_acpi.c

acpica: rework INTRNG interrupts

pci_host_generic*: basic implementation of bus range

pci_host_generic: allocate resources against devices

pci_host_generic: remove unneeded ThunderX2 quirk

Addressed markj's comments.

use the UID instead of APIC id in prints for arm64
the comment on 'max' is already handled in preceding commit

Addressed markj's comment - removed unnecessary includes.
