2010-01-13pci: Add missing 'const' in argument to pci_get_xxxStefan Weil1-7/+7
pci_get_byte, pci_get_word, pci_get_long and pci_get_quad all take a const uint8_t pointer, because they only read the configuration data. Their prototypes should reflect this fact. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-01-13eepro100: Update ROM file supportStefan Weil1-10/+1
Use new way to associate ROM files to devices. Currently, there is only a ROM file for i82559er included in QEMU, so the patch does not add .romfile for the other devices. When flexible mode is fixed in eepro100, adding more ROM files will be possible. It should be possible to create them from pxe-i82559er.bin, because etherboot uses the same driver for all eepro100 devices (only PCI ids differ). Maybe it is even possible to create a single pxe-i8255x.bin which supports all eepro100 devices (not supported with current etherboot).

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

2010-01-11roms: minor fixes and cleanups.Gerd Hoffmann2-17/+26

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>
2010-01-11virtio-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. Tsirkin <mst@redhat.com> Acked-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

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: 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.

2010-01-08debugcon: support for debugging consoles (e.g. Bochs port 0xe9)H. Peter Anvin1-0/+107
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 Jarno1-2/+7
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.
