Port qemu-kvm's commit 4b62fff1101a7ad77553147717a8bd3bf79df7ef Author: Huang Ying <ying.huang@intel.com> Date: Mon Sep 21 10:43:25 2009 +0800 MCE: Relay UCR MCE to guest UCR (uncorrected recovery) MCE is supported in recent Intel CPUs, where some hardware error such as some memory error can be reported without PCC (processor context corrupted). To recover from such MCE, the corresponding memory will be unmapped, and all processes accessing the memory will be killed via SIGBUS. For KVM, if QEMU/KVM is killed, all guest processes will be killed too. So we relay SIGBUS from host OS to guest system via a UCR MCE injection. Then guest OS can isolate corresponding memory and kill necessary guest processes only. SIGBUS sent to main thread (not VCPU threads) will be broadcast to all VCPU threads as UCR MCE. aliguori: fix build Signed-off-by: NMarcelo Tosatti <mtosatti@redhat.com> Signed-off-by: NAvi Kivity <avi@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

In QEMU-KVM, physical address != RAM address. While MCE simulation needs physical address instead of RAM address. So kvm_physical_memory_addr_from_ram() is implemented to do the conversion, and it is invoked before being filled in the IA32_MCi_ADDR MSR.

When qemu is configured with --enable-debug-tcg, gcc throws this warning (or error with -Werror): tcg/tcg.c:1030: error: comparison of unsigned expression >= 0 is always true Fix it by removing the >= 0 part. The type cast to 'unsigned' catches negative values of op (which should never happen). This is a modification of Hollis Blanchard's patch.

This patch updates the vmmouse handler registration and activation. Old behavior: vmmouse_read_id, vmmouse_request_relative and vmmouse_request_absolute unregister the handler and re-register it. New behavior: vmmouse_request_relative and vmmouse_request_absolute will unregister the handler in case the mode did change. Then register and active the handler with current mode if needed. Note that the old code never ever *activates* the handler, so the vmmouse doesn't receive events. This trips up Fedora 14 for example: Boot a default install without usb tablet, watch the X-Server activating the vmmouse then, enjoy a non-functional mouse.

readv & writev, read & write respectively from the current offset of the file & hence their use has to be preceeded by a call to lseek. preadv/writev can be used instead, as they take the offset as an argument. This saves one system call( lseek ). In case preadv is not supported, it is implemented by an lseek followed by a readv. Depending upon the configuration of QEMU, the appropriate read & write methods are selected. This patch also fixes the zero byte read/write bug & obviates the need to apply a fix for that bug separately. Signed-off-by: NM.

The O_DIRECT flag imposes alignment restrictions on the length and address of userspace buffers and the file offset of I/Os. While VirtFS/9P has plans to implement O_DIRECT behavior on the server, for now we will stick to a behavior like NFS by bypassing the page cache only on the client. Server may still cache the I/O.

When 9P server fails to create a file due to permission problems it should return EPERM. However the current 9P2000.L code returns EBADF. EBADF is NOT a valid return value from open() call. The problem is because we do not preserve the errno variable properly. If the file open had failed, the call to close() on the fd in v9fs_post_lcreate() fails and sets errno to EBADF. We should preserve the errno that we got from open() and we should call close() only if we had a valid fd.
