Add optional MSI-X support: use a vector per virtqueue with fallback to a common vector and finally to regular interrupt. Teach all drivers to use it. I added 2 new virtio operations: request_vqs/free_vqs because MSI needs to know the total number of vectors upfront. Signed-off-by: Michael S.

Since OMAP UART has a few distinct features than common 8250 UART, I re-implemented its driver rather than porting it based on ns16550.c. There are mainly two big differences between the implementations. First, OMAP UART introduces the concept of register access mode, which divides the register map into seperated space. Switching the access mode is then necessary when configuring it. Second, THRE

Hi Ian, I am trying to add supporting dumping 32-bit guest on arm32 to see what happened in my dom0 kernel when booting. It seems gvirt_to_maddr() is not workable under arm32. But why has it been implemented both in include/asm-arm/arm{32,64}/page.h? Thanks.

Hi Julien, Since Ian has merged most my OMAP5 patches, I decide to try to update my working tree to it today. However, it seems it doesn't work as expected. There mainly two kind of problems that I met: 1. It seems that xen no longer maps some of io memory regions described in dts. For example, the memory regions in "ocp" node of omap5.dtsi. 2. commit c88d32f4 seems to be conflict

This implements optional MSI-X support in virtio_pci. MSI-X is used whenever the host supports at least 2 MSI-X vectors: 1 for configuration changes and 1 for virtqueues. Per-virtqueue vectors are allocated if enough vectors available. Signed-off-by: Michael S.

Hi all, I noticed that upstream UEFI is now supported ARMv8 on FastModel. I’ve tried it to boot Linux with it. And it works. But it seems it still cannot load Xen hypervisor properly. I’m now looking for the reasons. Is there any difference for a firmware to load Xen and Linux kernel? Cheers, Baozi

Since both UART driver codes on Allwinner A31, OMAP5 and x86 would use these definitions, we refactor the codes into a separated header to avoid unnecessary duplication.
