2010-01-11pc: add rombar to compat properties for pc-0.10 and pc-0.11Gerd Hoffmann1-0/+8
So '-M pc-0.10' and '-M pc-0.11' will use the fw_cfg rom load method by default. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-01-11pci: allow loading roms via fw_cfg.Gerd Hoffmann2-0/+16
This patch adds a pci bus property 'rombar' which specifies whenever the pci rom should be loaded via pci rom bar (default) or via fw_cfg. The later can be used for compatibility with older qemu versions where no pci rom bar is present. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-01-11roms: rework rom loading via fwGerd Hoffmann3-13/+7
This patch changes the way rom loading via fw_cfg is handled. Instead of having pc_init1() call a function which passed all roms to the firmware config we simply pass a pointer to fw_cfg to the rom loader. Advantage: loading roms via firmware works also for devices which are initialized after pc_init1(), i.e. everyting added via -device.

2010-01-11fw_cfg: rom loader tweaks.Gerd Hoffmann1-7/+11
Changes: - make dir argument mandatory, we allways have one anyway (vgaroms or genroms). - check for duplicates, skip loading if found. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-01-11roms: minor fixes and cleanups.Gerd Hoffmann2-17/+26
Changes: - Drop extra file argument from rom_add_file(). - Drop fw_dir check in do_info_roms, we allways have a dir name. - code style fixes. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-01-11pc: add machine type for 0.12Gerd Hoffmann1-1/+17
Add a new machine type for qemu 0.12. Also fixup the 0.11 machine type: msi for virtio-blk-pci was enabled after the 0.11 release, so turn it off in the 0.11 machine type. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-01-11Handle TFTP ERROR from clientThomas Horsten1-0/+23
If a PXE client only wants to find out the size of a file, it will open the file and then abort the transfer by sending a TFTP ERROR packet. The ERROR packet should cause qemu to terminate the session. If not, the sessions will soon run out and cause timeouts in the client. Also, if a TFTP session already exists with same IP/UDP port, it should be terminated when a new RRQ is received, instead of creating a duplicate (which will never be used). A patch for gPXE to send the ERROR packet is also being submitted to gPXE. Together they resolve slowness/hanging when booting pxegrub from qemu's internal TFTP server. The patch from Milan Plzik to return after sending OACK is also required for a complete fix.

2010-01-11dmg: fix ->open failureChristoph Hellwig1-14/+14
Currently the dmg image format driver simply opens the images as raw if any kind of failure happens. This is contrarty to the behaviour of all other image formats which just return an error and let the block core deal with it.

2010-01-11virtio-pci: thinko fixMichael S. Tsirkin1-1/+1
Since patch ed757e140c0ada220f213036e4497315d24ca8bct, virtio will sometimes clear all status registers on bus master disable, which loses information such as VIRTIO_CONFIG_S_FAILED bit. This is a result of a patch being misapplied: code uses ! instead of ~ for bit operations as in Yan's original patch. This obviously does not make sense. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-01-11virtio: add features as qdev propertiesMichael S. Tsirkin12-50/+91
Add feature bits as properties to virtio. This makes it possible to e.g. define machine without indirect buffer support, which is required for 0.10 compatibility, or without hardware checksum support, which is required for 0.11 compatibility. Since default values for optional features are now set by qdev, get_features callback has been modified: it sets non-optional bits, and clears bits not supported by host. Signed-off-by: Michael S.

2010-01-11qdev: add bit property typeMichael S. Tsirkin2-7/+66
This adds "bit" property type, which is a boolean stored in a 32 bit integer field, with legal values on and off. Will be used by virtio for feature bits. Signed-off-by: Michael S.

2010-01-11lsi: pass lsi_request to lsi_reselectGerd Hoffmann1-16/+7

2010-01-11lsi: have lsi_request for the whole life time of the request.Gerd Hoffmann1-21/+32
Right now lsi_request is allocated when a request is queued and released when a request is unqueued. With this patch applied the lsi_request is kept for the whole lifetime of the scsi request. Rationale: We can use it for per-request data then. The patch does that already for the request tag.

2010-01-11MCE: Fix bug of IA32_MCG_STATUS after system resetHuang Ying1-0/+2
Now, if we inject a fatal MCE into guest OS, for example Linux, Linux will go panic and then reboot. But if we inject another MCE now, system will reset directly instead of go panic firstly, because MCG_STATUS.MCIP is set to 1 and not cleared after reboot. This is does not follow the behavior in real hardware. This patch fixes this via set env->mcg_status to 0 during system reset.

2010-01-08linuxboot: fix gdt address calculationAvi Kivity1-2/+3
The gdt address calculation in linuxboot.bin is broken in two ways: first it loads %cs into %eax, but that instruction leaves the high bits of %eax undefined and we did not clear them. Secondly, we completely ignore the incorrect %eax, and use the undefined %ebx instead. With these issues fixed, linuxboot works again.

2010-01-08debugcon: support for debugging consoles (e.g. Bochs port 0xe9)H. Peter Anvin4-1/+142
Add generic support for debugging consoles (simple I/O ports which when written to cause debugging output to be written to a target.) The current implementation matches Bochs' port 0xe9, allowing the same debugging code to be used for both Bochs and Qemu. There is no vm state associated with the debugging port, simply because it has none -- the entire interface is a single, stateless, write-only port. Most of the code was cribbed from the serial port driver. v2: removed non-ISA variants (they can be introduced when/if someone wants them, using code from the serial port); added configurable readback (Bochs returns 0xe9 on a read from this register, mimic that by default) This retains the apparently somewhat controversial user friendly option, however. v3: reimplemented the user friendly option as a synthetic option ("-debugcon foo" basically ends up being a parser-level shorthand for "-chardev stdio,id=debugcon -device isa-debugcon,chardev=debugcon") -- this dramatically reduced the complexity while keeping the same level of user friendliness. v4: spaces, not tabs. v5: update to match current top of tree. Calling qemu_chr_open() already during parsing no longer works; defer until we are parsing the other console-like devices. Signed-off-by: H.

2010-01-08Use vpath directivePaolo Bonzini7-13/+16
The vpath directive has two advantages over the VPATH variable: 1) it allows to skip searching of .o files; 2) the default semantics are to append to the vpath, so there is no confusion between "VPATH=xyz" and "VPATH+=xyz". Since "vpath %.c %.h PATH" is not valid, I'm introducing a wrapper macro to append one or more directories to the vpath.
