[Qemu-devel] [PATCH v7 00/11] QEMU: Support KVM on ARM

[Peter Maydell]

KVM ARM support has just hit Linus' kernel tree, so we can
finally commit this series to QEMU. Since all the patches got
reviewed last time round this should be ready to commit.
I plan to commit this via arm-devs.next.

NB: the linux-headers sync is against Linus' mainline, and
so I had to make a few minor tweaks to avoid the QEMU patch
reverting some s390 and ppc changes which haven't yet hit
mainline. (Can't sync vs kvm-next kernel tree because ARM
KVM hasn't got there yet...)

thanks

Changes v6 to v7:
 * added new patch 3 to drop CPUARMState* from bank_number()
 * patch 4 (old 3): trivial renaming of a few variables for
   consistency, use 'return 0;' instead of 'int ret = 0; return ret;'
 * added new patch 7 to convert gic classes to realize
 * updated patch 9 (old 7) to use realize not init
 * added blank lines in a few places to separate variable
   declarations from code
Changes v5 to v6:
 * rebase
 * fixed stupid typo of arm_gic vs arm-gic
 * added a patch updating MAINTAINERS
 * kernel headers patch now is from a valid tree to sync against
Changes v4 to v5:
 * no changes of consequence, but rebased on current qemu master
   and resynced with v17 of the kernel patches (minor ABI changes
   caused by other people getting in first for ioctl numbers etc,
   and insertion of "_ARM_" in KVM_ARM_SET_DEVICE_ADDRESS related
   constants
Changes v3 to v4:
 * minor updates to match kernel ABI changes (ID field in
   kvm_device_address is now 64 bits, core register offsets now
   changed due to use of pt_regs struct)
 * squashed the two 'update kernel headers' patches, since the
   plan is for vgic support to go upstream at the same time as
   the baseline kernel patchset
 * added a new patch 8 which adds ARM to the list of Linux archs
   which prefer 2MB alignment so they can use transparent hugepages
Changes v2 to v3:
 * applied various minor tweaks suggested during review of v2
 * rebased on master, resynced with kernel headers for v13
 * new patch 6 which uses a MemoryListener to track where the
   VGIC memory regions are mapped, so we can tell the kernel
   where they live in the memory map (via new ioctl
   KVM_SET_DEVICE_ADDRESS)
