Finally I got around to breaking up the similarly named monolithic patch that caused a regression shortly before the 4.2 release and got therefore reverted. This series consists of the broken up pieces that - according to my testing - don''t expose the reported lockup; the 7th will need debugging to understand what''s wrong there. 1: use RTC_* names instead of literal numbers 2:

This patch series makes suspend support in qemu alot more useful. Right now the guest can put itself into s3, but qemu will wakeup the guest instantly. With this patch series applied the guest will stay suspended instead and there are a few events which can kick the guest out of suspend state: A monitor command, ps/2 input, serial input, rtc. Not much yet, but it''s a start with the

Dear all: I have found a big bug on xen concerning time virtualization. Please let me show you the whole process: 1 Phenomenon when I run a JVM based program in IE browser in my Virtual Machine, I have found clearly that time at the right bottom corner in my VM gets more slower and slower. I studied the bug deeply, and found something below. 2 Xen vmx_vmexit_handler --> ......... -->

When running on PowerPC, we don''t have native PIO support. There are a few hacks around to enable PIO access on PowerPC nevertheless. The most typical one is the isa-mmio device. It takes MMIO requests and converts them to PIO requests on the (QEMU internal) PIO bus. This however is not how real hardware works and it limits us in the ability to spawn eventfd''s on PIO ports
