similar to: [PATCH+RFC+HACK 00/16] xen: arm initial support for xgene arm64 platform

George has release acked all of these. Otherwise mostly minor updates this time around. Summary: A == acked, M == modified A xen: arm64: Add 8250 earlyprintk support A xen: arm64: Add Basic Platform support for APM X-Gene Storm. A xen: arm64: Add APM implementor id to processor implementers. M xen: arm: add a quirk to handle platforms with unusual GIC layout A xen: arm: allow platform

From: Pranavkumar Sawargaonkar <pranavkumar@linaro.org> This patch adds initial platform stubs for APM X-Gene. Signed-off-by: Anup Patel <anup.patel@linaro.org> Signed-off-by: Pranavkumar Sawargaonkar <pranavkumar@linaro.org> Drop earlyprintk (split into earlier patch). Only build on ARM64. Drop empty init and reset hooks and enable 1:1 workaround. Signed-off-by: Ian

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

This patch fixes size of ttbcr register (TCR_EL1 in case of AArch64) and it''s programming considering size in case of context switch. Currently ttbcr is defined as 32b register but for AArch64 TCR_EL1 size is 64b.

This patch series implements SMP boot for arch/arm, as far as getting all CPUs up and running the idle loop. Changes from v1: - moved barriers out of loop in udelay() - dropped broken GIC change in favour of explanatory comment - made the increment of ready_cpus atomic (I couldn''t move the increment to before signalling the next CPU because the PT switch has to happen between

Hello everyone, this is the very first version of the patch series that introduces ARMv7 with virtualization extensions support in Xen. The series allows Xen and Dom0 to boot on a Cortex-A15 based Versatile Express simulator. See the following announce email for more informations about what we are trying to achieve, as well as the original git history: See

Hello everyone, this is the fourth version of the patch series that introduces ARMv7 with virtualization extensions support in Xen.

See http://www.gossamer-threads.com/lists/xen/devel/297170 for some information on how to get this going. I''ve rebased and addressed the review comments. With this rebase I''ve picked up some patches from Julien which were required to do things properly, so the gic v7 and device blacklisting patches have been changed to use the proper mechanisms. Previously I was able to boot

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

Biggest change is to switch the new DTB node to /xen-core-devices instead of /xen at Stefano''s request. I also dropped the few patches title HACK etc which weren''t supposed to be there and fixed up some bits and pieces which folks commented on. George, WRT the freeze I think this is functionality which we cannot ship Xen 4.4 without. The impact is entirely constrained to the

I''ve addressed all (I think/hope) of the review comments. The main change is to expose the guest virtual platform (e.g. memory layout and interrupt usage etc) to the toolstack via the public interface. This is then used during FDT generation. I have just codified the current defacto standard layout, it''s probably not the best layout but any change can be a separate patch/series.

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, Julien Grall (2): xen/arm: don''t enable VFP on XEN

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.

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.

Hi, I want to try Xen on ARMv8 Simulator. Can you please provide guidance?. I am looking for information about sources, build and procedure to launch Xen on ARMv8 Thanks & Regards Vijay

We are currently initializing GIC irq properties (ITARGETSR, IPRIORITYR, and GICD_ICFGR) only in gic_route_irq, that is not called for guest interrupts at all. Move the initialization into a separate function (gic_set_irq_properties) and call it from gic_route_irq_to_guest. Changes in v2: - rebased on 77d3a1db3196b1b5864469f8d3f41d496800c795.

This round implements all of the review comments from V2 and all patches are now acked. Unless there are any objections I intend to apply later this morning. Ian.

Hi, V6: The only change from V5 is in patch #6: - changed comment to reflect autoxlate - removed a redundant ASSERT - reworked logic a bit so that get_page_from_gfn() is called with NULL for p2m type as before. arm has ASSERT wanting it to be NULL. Tim: patch 4 needs your approval. Daniel: patch 5 needs your approval. These patches implement PVH dom0. Patches 1 and 2
