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

On !SMP systems spinlocks do not exist. Thus checking of they are active will always fail. Use assert_spin_locked(lock); instead of BUG_ON(!spin_is_locked(lock)); to not BUG() on all UP systems.

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

The IRQ handling code requires pcidevs_lock to be held only for MSI interrupts. As the handling of which was now fully moved into msi.c (i.e. while applying fine without, the patch needs to be applied after the one titled "x86: split MSI IRQ chip"), io_apic.c now also doesn''t need to include PCI headers anymore.

This patch enables PCI passthrough with stub domain. PCI passthrough with stub domain has failed in the past. The primary reason is that hypercalls from qemu in stub domain are rejected. This patch allows qemu in stub domain to call the hypercalls which is needed for PCI passthrough. For security, if target domain of hypercall is different from that of stub domain, it rejects hypercall. To use

The only changes are the incorporation of various review comments. The latter part of
