2009-04-09Register a single area for vga bios and option romspbrook
Those guys are not different in nature. They're all roms, not blessed with the graces of being written to. So there's not need to issue multiple requests to memory registration areas: just treat them as brothers, and put them all in the same region. It also has the nice side effect of improving the loading code a little bit. Besides some of the ugliness going away, we're now avoiding phys_ram_base dependencies in option rom code.

2009-04-07Fix crash on resolution change -> screen dump -> vga redraw (Avi Kivity)aliguori
The vga screen dump function updates last_width and last_height, but does not change the DisplaySurface that these variables describe. A consequent vga_draw_graphic() will therefore fail to resize the surface and crash. Fix by invalidating the display state after a screen dump, forcing vga_draw_graphic() to reallocate the DisplaySurface.

2009-04-05Fix display breakage when resizing the screen (v2) (Avi Kivity)aliguori
When the vga resolution changes, a new display surface is not allocated immediately; instead that is deferred until the next update. However, if we're running without a display client attached, that won't happen and the next bitblt is likely to cause a segfault by overflowing the display surface. Fix by reallocating the display immediately when the resolution changes. Tested with (Windows|Linux) x (cirrus|std) x (curses|sdl).

2009-03-28Clean some PCI defines (Stefan Weil)aliguori
this patch adds some more defines from linux/pci_regs.h to hw/pci.h. There is now no longer a need to define them in eepro100.c, so they were removed there. Some defines from linux/pci_regs.h had similar, but not the same defines in hw/pci.h (PCI_REVISION_ID / PCI_REVISION, PCI_SUBSYSTEM_VENDOR_ID / PCI_SUBVENDOR_ID, PCI_SUBSYSTEM_ID / PCI_SUBDEVICE_ID). I suggest to use the "standard" from linux/pci_regs.h and replace the "old" Qemu ones. To facilitate the migration, my patch does not remove the old defines but marks them as obsolete. After a migration to the "standard" defines, pci.h could use linux/pci_regs.h which is far more complete. The patch is needed for an updated maintainer version of hw/eepro100.c which I'd like to see in Qemu stable. * Remove declarations already declared in header file from eepro100.c * Add missing declarations from pci_regs.h to pci.h * Mark "non-standard" declarations in pci.h as obsolete Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6901 c046a42c-6fe2-441c-8c8c-71466251a162

2009-03-28get roms more room. (Glauber Costa)aliguori
This patch increases by 50 % the size available for option roms. The main motivator is that some roms grew bigger than the 64k we currently allocate for them (Hey, it's 2009!) One example is the gpxe project, that produces some roms with 69k, 70k, etc. The space proposed by this patch actually makes it as big as 84k. Probably still a fit for some time. But there is no free lunch. This space must come from somewhere, and we take it from vga rom space. Currently, our vga roms are around 35k in size. With this patch, option rom space will begin just after vga ends, aligned to the next 2k boundary. Technicaly, we could do the same with the uper space (the bios itself), but since bochs bios is already 128 k in size, I don't see an urgent need to do it.

2009-03-28new scsi-generic abstraction, use SG_IO (Christoph Hellwig)aliguori
Okay, I started looking into how to handle scsi-generic I/O in the new world order. I think the best is to use the SG_IO ioctl instead of the read/write interface as that allows us to support scsi passthrough on disk/cdrom devices, too. See Hannes patch on the kvm list from August for an example. Now that we always do ioctls we don't need another abstraction than bdrv_ioctl for the synchronous requests for now, and for asynchronous requests I've added a aio_ioctl abstraction keeping it simple. Long-term we might want to move the ops to a higher-level abstraction and let the low-level code fill out the request header, but I'm lazy enough to leave that to the people trying to support scsi-passthrough on a non-Linux OS. Tested lightly by issuing various sg_ commands from sg3-utils in a guest to a host CDROM device.
