Linaro Virtualization Team's Weekly Report - Weeks 13/14 2013
=============================================================
During the last 2 weeks (27 March - 10 April 2013) the team has been
working on the following areas. More detailed information can be found
on the meeting reports wiki page [0].
Ongoing work
------------
* BOOTLOADER HYP MODE SUPPORT FOR ARMv7 [1]
by Andre Przywara
* rebase existing Versatile Express patches against upstream u-boot [2]
Done:
- Reworked patch for Versatile Express to be more reusable
for other boards.
- U-Boot patch sent as RFC, waiting for reaction.
* implement HYP command to let u-boot switch into HYP mode [3]
Done:
- HYP mode switch works reliably.
- SMP is working too.
- VExpress patches sent upstream (V3 of the patch set).
- discovered a bug in Linux 3.9-rc:
- DMA refactoring broke Versatile Express: NULL pointer
exception.
- Patches already are on ML, but not yet in HEAD
(3.9rc5-77)
- discovered related issue with DMA PL330 on Highbank
(Rob@Calxeda seems to care about this)
* ARMv7 KVM GUEST MIGRATION [4]
by Peter Maydell and Andre Przywara
* QEMU: audit the vexpress model for devices we use which do not
currently have migration support [5]
by Peter Maydell
Done:
- task completed.
- patches now preliminarily queued in arm-devs.next, though
if there is a late-breaking issue with one of them it will
have to be fixed and patches updated.
* QEMU: implement full cp15 sync with kernel [6]
by Peter Maydell
Done:
- Some work that was assumed to be already committed last
year appeared to be still pending - hew sub-task created:
QEMU: move CPU migration to vmstate [7]
Working on:
- pending for [7] to complete.
* QEMU: move CPU migration to vmstate [7]
Done:
- updated patches from Juan Quintela from last year which
are updating the migration state for the CPU itself to use
VMState structures.
Working on:
- testing and tweaking of the updated patches.
* kernel: agree on a data structure to describe timer state [8]
by Andre Przywara
Working on:
- reading documentation.
- thinking about code structure.
- timer migration prototype.
* ARMv8 KVM QEMU prototype [9]
* Add skeleton ARM64 build patches to local tree [10]
Done:
- completed this sub-task.
* Add arm64 mach-virt system model skeleton [11]
Working on:
- only has serial, can add virtio stuff later.
- in progress.
* Add creating FDT from scratch to mach-virt system model [12]
Working on:
- in progress, nearly done.
* Add kvm guest creation and launching of armv8/mach-virt [13]
Working on:
- in progress, just started.
* IN KERNEL SUPPORT FOR KVM ARMv8 [14]
by Anup Patel and Pranavkumar Sawargaonkar, Geoff Levand
Done:
- KVM ARMv8 patch set review, fixes suggested (by Geoff).
- Initial patch set for APM board bring up is reviewed
internally in APM and is queued for upstreaming in near
future.
- real AMRv8 hardware is accessible to Anup and Pranav -
switched to it for further work.
- ARMv8 kernel is bootable on the board now.
- U-Boot is starting the kernel in HYP mode on the board now.
Working on:
- Debugging the guest part now (on the board). Currently it is
not booting (still in early debug).
- Hacky early printk support in kvmtool is to be properly
submitted to the ML as an RFC.
* CI BRING UP: KVM ARMv7 [15]
by Riku Voipio
Done:
- Find out howto include guest image in host image.
- Create ci.linaro.org jobs for submitting validation tests to
LAVA for VE TC2.
Working on:
- Create ci.linaro.org jobs for submitting validation tests to
LAVA for Arndale.
