2010-01-13eepro100: Fix initial value for PCI_STATUSStefan Weil
The numerical value was wrong (0x2800 instead of 0x0280) which indeed did not make sense. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-01-12virtio-net: mac property is mandatoryMichael S. Tsirkin
Mac feature bit isn't going to work as all network cards already have a 'mac' property to set the mac address. Remove it from mask and add in get_features.

2010-01-11pc: add rombar to compat properties for pc-0.10 and pc-0.11Gerd Hoffmann
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 Hoffmann
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 Hoffmann
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 Hoffmann
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 Hoffmann
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 Hoffmann
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>
2010-01-11virtio-pci: thinko fixMichael S. Tsirkin
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. Tsirkin
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. Tsirkin <mst@redhat.com> Acked-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-01-11virtio: rename features -> guest_featuresMichael S. Tsirkin
Rename features->guest_features. This is what they are, avoid confusion with host features which we also need to keep around. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-01-11qdev: add bit property typeMichael S. Tsirkin
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. Tsirkin <mst@redhat.com> Acked-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-01-11lsi: pass lsi_request to lsi_reselectGerd Hoffmann
All callers of lsi_reselect have a lsi_request struct at hand anyway. So just pass it directly instead of having lsi_reselect search for it using the tag. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-01-11lsi: have lsi_request for the whole life time of the request.Gerd Hoffmann
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.

2010-01-08debugcon: support for debugging consoles (e.g. Bochs port 0xe9)H. Peter Anvin
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.

2010-01-03loader: don't call realloc(non_null, 0) when no symbols are presentAurelien Jarno
According to C99, realloc(non_null, 0) != free(non_null), that's why it is forbidden in QEMU. When there are no symbols, nsyms equals to 0. Free the syms structure and set it to NULL instead of reallocating it with a size of 0. This fixes -kernel with stripped kernels.
