2009-12-19roms: use new fw_cfg file xfer support.Gerd Hoffmann
roms: use fw_cfg for vgabios and option rom loading, additionally to deploying them the traditional way (copy to 0xc0000 -> 0xe0000 range). Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> (cherry picked from commit 379526a40e855b0da3c5718063a7d992aa5a79a1)
2009-12-19fw_cfg: add API for file transfer.Gerd Hoffmann
This patch adds a file transfer interface to fw_cfg. Intended to be used for passing non-pci option roms and vgabios to seabios. Namespace is modeled after the existing cbfs filesystem support in seabios. Reading the new FW_CFG_FILE_DIR entry returns a file list. Fields there are in network byte order (aka bigendian). aliguori: fix fw_cfg.h for multiboot.bin, add proper fw_cfg.h declarations, quiet fprintf() in fw_cfg.c Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> (cherry picked from commit abe147e0ce41c07e789f6627bcb01c905d1f9bbf)

2009-12-19pci romfiles: add property, add default to PCIDeviceInfoGerd Hoffmann
This patch adds a romfile property to the pci bus. It allows to specify a romfile to load into the rom bar of the pci device. The default value comes from a new field in PCIDeviceInfo. The property allows to change the file and also to disable the rom loading using an empty string.

2009-12-19Support PCI based option rom loadingAnthony Liguori
Currently, we preload option roms into the option rom space in memory. This prevents DDIM from functioning correctly which severely limits the number of roms we can support. This patch introduces a pci_add_option_rom() which registers the PCI_ROM_ADDRESS bar which points to our option rom. It also converts over the cirrus vga adapter, the rtl8139, virtio, and the e1000 to use this new mechanism. The result is that PXE boot functions even with three unique types of cards.

2009-12-19Fix VMware VGA depth computationAnthony Liguori
VMware VGA requires that the depth presented to the guest is the same as the DisplaySurface that it renders to. This is because it performs a very simple memcpy() to blit from one surface to another. We currently hardcode a 24-bit depth. The surface allocator for SDL may, and usually will, allocate a surface with a different depth causing screen corruption. This changes the code to allocate the DisplaySurface before initializing the device which allows the depth of the DisplaySurface to be used instead of hardcoding something.

2009-12-19Make sure to enable dirty tracking of VBE vram mappingAnthony Liguori
Apparently, VBE maps the VGA vram to a fixed physical location. KVM requires that all mappings of the VGA vram have dirty tracking enabled on them. Any access to the VGA vram through the VBE mapping currently fails to result in dirty page tracking updates causing a black screen. This is the true root cause of VMware VGA not working correctly under KVM and likely also an issue with some of the std-vga black screen issues too. Cirrus does not enable VBE so it would not be a problem when using Cirrus.

2009-12-19monitor: Catch printing to non-existent monitorLuiz Capitulino
The monitor_vprintf() function now touches the 'mon' pointer before calling monitor_puts(), this causes block migration to segfault as its functions call monitor_printf() with a NULL 'mon'. To fix the problem this commit moves the 'mon' NULL check from monitor_puts() to monitor_vprintf(). This can potentially hide bugs, but for some reason this has been the behavior for a long time.

2009-12-18osdep: Fix runtime failure on older Linux kernelsAndre Przywara
If QEMU finds newer kernel header files on compilation time, it will use advertised features like pipe2 or SOCK_CLOEXEC by just doing a compile test. If later the executables are executed on an older kernel (<2.6.27, like Xen Dom0 2.6.18), then QEMU will fail on opening sockets and creating pipes and returns the rather unspecific "qemu_init_main_loop failed". This patch fixes this by checking the return values of these calls for EINVAL and ENOSYS and falling back to the older versions automatically.

2009-12-13target-mips: fix user-mode emulation startupNathan Froyd
Running programs with the MIPS user-mode emulator fails during dynamic loading, as floating-point instructions are not enabled in in env->hflags. Move the code for doing so from fpu_init to cpu_reset so the MIPS_HFLAG_{FPU,F64} setting doesn't get clobbered by cpu_reset setting env->hflags to MIPS_HFLAG_UM. The same end can be achieved by swapping the ordering of fpu_init and cpu_reset in cpu_mips_init, but it seemed better to consolidate the CONFIG_USER_ONLY code into a single location.
