2009-05-08fix asynchronous ioctlsChristoph Hellwig
posix_aio_read expect aio requests to return the number of bytes requests to be successfull, so we need to fake this up for ioctls. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-08kvm: Trim cpu features not supported by kvmAvi Kivity
Remove cpu features that are not supported by kvm from the cpuid features reported to the guest. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-08Fix x86 feature modifications for features that set multiple bitsAvi Kivity
QEMU allows adding or removing cpu features by using the syntax '-cpu +feature' or '-cpu -feature'. Some cpuid features cause more than one bit to be set or cleared; but QEMU stops after just one bit has been modified, causing the feature bits to be inconsistent. Fix by allowing all feature bits corresponding to a given name to be set. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-05-08e1000: Do not reinit pci config space to 0Amit Shah
pci_register_device already mallocs the pci config space buffer filled with zeroes. Doing this again breaks some default config space writes like setting the subsystem vendor id and subsystem device id.

2009-05-08AIO deletion race fixAlexander Graf
When deleting an fd event there is a chance the object doesn't get deleted, but only ->deleted set positive and deleted somewhere later. Now, if we create a handler for the fd again before the actual deletion occurs, we end up writing data into an object that has ->deleted set, which is obviously wrong. I see two ways to fix this: 1. Don't return ->deleted objects in the search 2. Unset ->deleted in the search This patch implements 1. which feels safer to do. It fixes AIO issues I've seen with curl, as libcurl unsets fd event listeners pretty frequently. Signed-off-by: Alexander Graf <alex@csgraf.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-08reset state for load_linuxGlauber Costa
The linux loader is just an option rom like any other, just with some special requirements. Right now, our option rom resetting mechanism is not being applied to it. As a result, users using -kernel will not be able to successfully reboot their machines This patch fixes it by saving all the data we generated in the load_linux() function, to be used later by the option rom resetting mechanism.

2009-05-08register reset handler for option_romsGlauber Costa
Currently, boot options are not preserved across a system reset. option roms can modify themselves, or can for instance restore the real int 0x19 vector after they tried to boot from it. To properly do that, we need a reset handler registered to deal with option roms. This patch is based on current version on qemu-kvm.git Signed-off-by: Glauber Costa <glommer@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-05-08Drop CONFIG_GDBSTUBJan Kiszka
This is no user-flippable switch, and no arch makes use of disabling gdbstub support. So it's pointless to keep the related #ifdefs and configure hunks around - and risking breakages like 711c410fdd again. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>

2009-05-07Fix disassembler memory accessesBlue Swirl
Sparc disassembler wants to check previous addresses for some stuff and this may actually cause faults to be generated to the guest if the address is close to page start, because of the function used for the memory access. Fix by changing ldub_code to cpu_memory_rw_debug, which doesn't trigger exceptions. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2009-05-01suport device driver initialization modelGlauber Costa
According to PnP specification, Appendix B, Option ROMs that support DDIM (device driver initialization model) should have their memory space writeable. KVM deviates from us here, by removing the IO_MEM_ROM flag, to allow for PCI option ROMs (they require DDIM). However, there's absolutely no reason we can't do the same.

2009-05-01qemu-io: Optionally verify only part of read dataKevin Wolf
There are reasonable test cases where a read must span areas that are not uniformly filled with one pattern but contains several parts. This makes -P useless for them currently. Introducing additional options which determine the part of the read data that should be verified with the given pattern allows to check such reads.

2009-05-01net: Fix -net socket parameter checksJan Kiszka
My commit ea053add700d8abe203cd79a9ffb082aee4eabc0 broke -net socket by overwriting an intermediate buffer in the added check_param. Fix this by switching check_param to automatic buffer allocation and release, ie. callers no longer have to worry about providing a scratch buffer.
