[PATCH v2 0/3] KVM: selftests: Add get-reg-list regression test

[PATCH v2 0/3] KVM: selftests: Add get-reg-list regression test

[Andrew Jones]

This test was inspired by recent regression report about get-reg-list
losing a register between an old kernel version and a new one.

v2:
  - Added "... up to date with kernel version v5.10-rc2" comment
    to the blessed list [Marc]
  - Assert when an invalid command line argument is given rather
    than ignore it [drew]

Thanks,
drew

[PATCH v2 1/3] KVM: selftests: Add aarch64 get-reg-list test

[Andrew Jones]

Check for KVM_GET_REG_LIST regressions. The blessed list was
created by running on v4.15 with the --core-reg-fixup option.
The following script was also used in order to annotate system
registers with their names when possible. When new system
registers are added the names can just be added manually using
the same grep.

while read reg; do
	if [[ ! $reg =~ ARM64_SYS_REG ]]; then
		printf "\t$reg\n"
		continue
	fi
	encoding=$(echo "$reg" | sed "s/ARM64_SYS_REG(//;s/),//")
	if ! name=$(grep "$encoding" ../../../../arch/arm64/include/asm/sysreg.h); then
		printf "\t$reg\n"
		continue
	fi
	name=$(echo "$name" | sed "s/.*SYS_//;s/[\t ]*sys_reg($encoding)$//")
	printf "\t$reg\t/* $name */\n"
done < <(aarch64/get-reg-list --core-reg-fixup --list)

+ *
+ * Copyright (C) 2020, Red Hat, Inc.
+ *
+ * When attempting to migrate from a host with an older kernel to a host
+ * with a newer kernel we allow the newer kernel on the destination to
+ * list new registers with get-reg-list. We assume they'll be unused, at
+ * least until the guest reboots, and so they're relatively harmless.
+ * However, if the destination host with the newer kernel is missing
+ * registers which the source host with the older kernel has, then that's
+ * a regression in get-reg-list. This test checks for that regression by
+ * checking the current list against a blessed list. We should never have
+ * missing registers, but if new ones appear then they can probably be
+ * added to the blessed list. A completely new blessed list can be created
+ * by running the test with the --list command line argument.
+ *
+ * Note, the blessed list should be created from the oldest possible
+ * kernel. We can't go older than v4.15, though, because that's the first
+ * release to expose the ID system registers in KVM_GET_REG_LIST, see
+ * commit 93390c0a1b20 ("arm64: KVM: Hide unsupported AArch64 CPU features
+ * from guests"). Also, one must use the --core-reg-fixup command line
+ * option when running on an older kernel that doesn't include df205b5c6328
+ * ("KVM: arm64: Filter out invalid core register IDs in KVM_GET_REG_LIST")

[PATCH v2 2/3] KVM: selftests: Update aarch64 get-reg-list blessed list

[Andrew Jones]

The new registers come from the following commits:

commit 99adb567632b ("KVM: arm/arm64: Add save/restore support for
firmware workaround state")

commit c773ae2b3476 ("KVM: arm64: Save/Restore guest DISR_EL1")

commit 03fdfb269009 ("KVM: arm64: Don't write junk to sysregs on reset")

The last commit, which adds ARM64_SYS_REG(3, 3, 9, 12, 0) (PMCR_EL0),
and was committed for v5.3, doesn't indicate in its commit message that
enumerating it for save/restore was the plan. It's a good idea anyway,
since the other PMU registers have been enumerated since v4.10.

[PATCH v2 3/3] KVM: selftests: Add blessed SVE registers to get-reg-list

[Andrew Jones]

Add support for the SVE registers to get-reg-list and create a
new test, get-reg-list-sve, which tests them when running on a
machine with SVE support.
