[PATCH v5 0/7] Dissociate logical and gic/hardware CPU ID
Hi,
This is the fifth version of this patch series.
With the Versatile Express TC2, it''s possible to boot only with A7 or A15. If
the user choose to boot with only A7, the CPU ID will start at 0x100. As Xen
relies on it to set the logical ID and the GIC, it won''t be possible to use
Xen with this use case.
This patch series is divided in 3 parts:
- Patch 1: prepare Xen

[PATCH+RFC+HACK 00/16] xen: arm initial support for xgene arm64 platform
I''m afraid this series is rather a grab bag and it is distressingly
large at this stage. With this series I can boot an Xgene board until it
fails to find its SATA controller. This is a dom0 issue for which
patches are pending from APM (/me nudges Anup).
As well as the APM specific platform stuff there are also some generic
improvements which were either necessary or useful during this

[PATCH v2] arm: add few checks to gic_init
Check for:
- uninitialized GIC interface addresses;
- non-page aligned GIC interface addresses.
Panic in both cases.
Also remove the code from GICH and GICC to handle non-page aligned
interfaces.

[PATCH] xen: arm: improve VMID allocation.
The VMID field is 8 bits. Rather than allowing only up to 256 VMs per host
reboot before things start "acting strange" instead maintain a simple bitmap
of used VMIDs and allocate them statically to guests upon creation.
This limits us to 256 concurrent VMs which is a reasonable improvement.
Eventually we will want a proper scheme to allocate VMIDs on context switch.
The existing code

[PATCH 00/45] initial arm v8 (64-bit) support
First off, Apologies for the massive patch series...
This series boots a 32-bit dom0 kernel to a command prompt on an ARMv8
(AArch64) model. The kernel is the same one as I am currently using with
the 32 bit hypervisor
I haven''t yet tried starting a guest or anything super advanced like
that ;-). Also there is not real support for 64-bit domains at all,
although in one or two places I

I''ve rebased and addressed the review comments.
As before several of the patches are not to be applied because they can
be done better using infrastructure from Julien''s "Allow Xen to boot

[PATCH v2 0/2] Implement VFP context switch for arm32
Hello,
This is the second version of this patch series.
I only implement the VPF context switch support for arm32 and add dummy function
to avoid compilation on arm64.
I have switched the order of the patch because the old second one can be applied
alone and the patch are cleaner :).
For all the changes see each patch.
Cheers,

[PATCH] xen/arm: Missing +1 when then number of interrupt lines for the GIC is computed
In the GIC manual, the number of interrupt lines is computed with the following
formula: 32(N + 1) where N is the value retrieved from GICD_TYPER.

[PATCH v3] arm: support fewer LR registers than virtual irqs
If the vgic needs to inject a virtual irq into the guest, but no free
LR registers are available, add the irq to a list and return.
Whenever an LR register becomes available we add the queued irq to it
and remove it from the list.
We use the gic lock to protect the list and the bitmask.

[PATCH v2 2/4] xen/arm: do not use is_running to decide whether we can write directly to the LR registers
During context switch is_running is set for the next vcpu before the
gic state is actually saved.
This leads to possible nasty races when interrupts need to be injected
after is_running is set to the next vcpu but before the currently
running gic state has been saved from the previous vcpu.
Use current instead of is_running to check which one is the currently
running vcpu: set_current is called

optimization
Hi all,
I'm busy doing optimizations for vorbis. Don't have time for it, but still
doing it :-)
Some suggestions: there are some double function names:
forward/inverse
pack/unpack
look/free_look/free_info
and maybe more.
If they were renamed to time0_forward etc. profiling would be a lot
easier.
Oh, and add -fno-inline to $PROFILE in the Makefiles (or configure).

[PATCH v2] xen/gic: EOI irqs on the right pcpu
We need to write the irq number to GICC_DIR on the physical cpu that
previously received the interrupt, but currently we are doing it on the
pcpu that received the maintenance interrupt. As a consequence if a
vcpu is migrated to a different pcpu, the irq is going to be EOI''ed on
the wrong pcpu.
This covers the case where dom0 vcpu0 is running on pcpu1 for example
