2010-10-27Merge branch 'pci' into for_anthonyMichael S. Tsirkin
2010-10-27pcie: update satus on resetMichael S. Tsirkin
Reset never triggers a new event, so it's enough to update status. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-10-27msi: minor cleanupsMichael S. Tsirkin
Comment fixup (tell what it does not what it does not do), typo fix, whitespace fix. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-10-27msi: simplify range checksMichael S. Tsirkin
config write handlers should be idempotent. So no need for complex range checks: a simple one checking that we are touching the relevant capability will do. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-10-27pci: improve w1c mask handlingMichael S. Tsirkin
- save/restore must not check w1c bits since they are in fact guest controlled - clear w1c bits on reset Note: for express there are different kinds of reset, some leave part of config space alone. We will likely need a sticky bit mask to implement this. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-10-27pcie: clean up hot plug notificationMichael S. Tsirkin
Simplify logic for hotplug notification, by tracking state of the logical interrupt condition. We then simply use this variable to make the interrupt decision, according to spec. API is made cleaner as we no longer force users to pass in old slot control value. Includes fixes by Isaku Yamahata. Signed-off-by: Michael S.

2010-10-27Introduce range.hBlue Swirl
Extract range functions from pci.h. These will be used by later patches by non-PCI devices. Adjust current users. Signed-off-by: Blue Swirl <blauwirbel@gmail.com> (cherry picked from commit bf1b00712375bea65f2254dea8281fa646eebbd5)
2010-10-27qemu-options.def: add to generated header listMichael S. Tsirkin
All files include qemu-options.h which pulls in qemu-options.def from the root directory. Thus generating qemu-options.def from Makefile.objs under the target directory is not effective. Further, people expect .def file to get cleaned with make clean: it does not have state so no reason to defer removing it until distclean. Also add a rule to remove old files that might be around. This fixes the error: ‘QEMU_OPTION_spice’ undeclared (first use in this function) error that some people reported which is really down to an out of date .def file. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-10-27net: properly handle illegal fd/vhostfd from command lineJason Wang
When hanlding fd/vhostfd form command line through net_handle_fd_param(), we need to check mon and return value of strtol() otherwise we could get segmentation fault or invalid fd when user type an illegal fd/vhostfd.

2010-10-27virtio: sanity-check available indexMichael S. Tsirkin
Checking available index upon load instead of only when vm is running makes is easier to debug failures. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-10-27migration: don't segfault on invalid inputMichael S. Tsirkin
host_from_stream_offset returns NULL on error, return error instead of trying to use that address, to avoid segfault on invalid stream. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-10-23qemu-timer: move commonly used timer code to qemu-timer-commonBlue Swirl
Move timer init functions to a new file, qemu-timer-common.c. Make other critical timer functions inlined to preserve performance in qemu-timer.c, also move muldiv64() (used by the inline functions) to qemu-timer.h. Adjust block/raw-posix.c and simpletrace.c to use get_clock() directly. Remove a similar/duplicate definition in qemu-tool.c. Adjust hw/omap_clk.c to include qemu-timer.h because muldiv64() is used there. After this change, tracing can be used also for user code and simpletrace on Win32.

2010-10-23rewrite i386 tests MakefilePaolo Bonzini
1) compute path to i386 compiler from configure. If it is found, run the i386 tests. I use macros so that this approach could be applied for other arches as well. 2) provide an easily extensible way to add tests Most tests fail, but at least "make test" does something meaningful.

Many other tests fail, but this has an infinite loop with both qemu-i386 and native execution (albeit on x86_64), so there is something more going on.

2010-10-22Replace remaining gcc format attributes by macro GCC_FMT_ATTR (format checking)Stefan Weil

2010-10-22Remove special handling of system include files (no longer needed)Stefan Weil
The formerly used dyngen code did not work with system include files like stdio.h. Tests with Linux, OSX and Win32 show that this restriction is no longer needed. So we hopefully can remove that special piece of code. This results in cleaner code and allows better use of the new GCC_FMT_ATTR macro.

2010-10-20MCE: Relay UCR MCE to guestMarcelo Tosatti
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: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-10-20Add RAM -> physical addr mapping in MCE simulationHuang Ying
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.

2010-10-20vmmouse: adapt to mouse handler changes.Gerd Hoffmann
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.

2010-10-20[virtio-9p] Use preadv/pwritev instead of readv/writevSanchit Garg
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: M.
