Couple of patches to fix an overflow, optimize a bit and support bigger resolutions using Windows 8.

...o that i have alsa-backed sound emulation , for some reason i have only oss-backed if not applied ?!) Before all that, you need to read out the VGA Bios of the to-be-passthroughed- Graphiccard with a tool; i used nvflash.exe under DOS for this task. The patches assume you saved this file as "vgabios-pt.bin" 1. check out xen unstable: hg clone http://xenbits.xensource.com/xen-unstable.hg 2. go into there and do an "initial build" so that qemu-dm gets checked-out: cd xen-unstable.hg; cd tools; make ; make clean 3. apply the patches from within the "xen-unstable.hg&...

Hi, When I first built my Debian package, I needed to depend on qemu-system | qemu, since there was no other ways to pull needed BIOS files. It seems the situation changed, and that I could depend on less stuff from the qemu package. Maybe only the package named "etherboot" and "vgabios". To do that, my plan is to simply package a folder named: /usr/share/xen/qemu with in it symlinks, in a similar way of what you can find in /usr/share/qemu So, my question is simple. Out of this, what do I need for xen-qemu-dm? zigo at GPLHost:buzzig>_ /usr/share/qemu$ ls -lah 4.0K...

This patch supports basic gfx passthrough on QEMU: - disable emulated VGA adpater if there is passthroughed gfx - register/unregister legacy VGA I/O ports and MMIOs for passthroughed gfx Signed-off-by: Ben Lin <ben.y.lin@intel.com> Signed-off-by: Weidong Han <weidong.han@intel.com> _______________________________________________ Xen-devel mailing list

This patch set mainly allows the user to build a seabios or rombios only version of hvmloader. In addition, when building a seabios only hvmloader, Option ROMs like vgabios and etherboot are no longer required, and therefore can be disabled from the build. Dependency on the bcc compiler can also be avoided the same way. v2: Separate patches for separate issues Introduced config option to select which NIC to build ROM for Fixed initial patch to build multiple...

A "main" function is defined in Xen-3.1.0-source/tools/firmware/hvmloader/hvmloader.c. In this main function, rombios, vgabios and vmxassist are copied to specified address, with following commands memcpy((void *)ROMBIOS_PHYSICAL_ADDRESS, rombios, rombios_sz); ... memcpy((void *)ETHERBOOT_PHYSICAL_ADDRESS, etherboot, sizeof(etherboot)); ....

Yes, vgabios code needs to know. Currently it has bar #2 for the vga framebuffer bar hardcoded. It's 16bit code. I don't feel like making the probing more complicated ... cheers, Gerd
