the behaviour as follows: * deny switching to fullscreen mode if the resolution is too high and print a message to the console * use windowed mode as fallback option if we are already in fullscreen mode and the new resolution is too high and print a message to the console Signed-off-by: Andreas

[kvm-devel] [PATCH] fix widescreen resolution issues (v3)

hi, I'm sorry for messing up the last patch, I shouldn't work that late... I added the changes to pc.h (VGA_RAM_SIZE) and split up the patch in a qemu part and a vgabios part. cheers, Andi --- kvm-61.orig/qemu/hw/vga_int.h 2008-02-19 15:58:28.0 +0100 +++ kvm-61/qemu/hw/vga_int.h

Re: [kvm-devel] [PATCH] fix widescreen resolution issues (v2)

hi, @Arne: Could you please test the patch with your setup? I hope it works this time... Yesno. It does (at least kvm does not crash), but it shows the same dialog problems as reported by Leslie: I'm quite sure that this issue isn't related to the widescreen fixes. This visual bug seems to

[kvm-devel] [PATCH] fix screen corruption bug in vga_draw_graphic()

hi, the attached patch fixes the screen corruption issues which were reported by others, see: http://article.gmane.org/gmane.comp.emulators.kvm.devel/13543 http://article.gmane.org/gmane.comp.emulators.kvm.devel/13409 The bug is kvm specific and can only be observed in graphics mode using

Re: [kvm-devel] [PATCH] fix widescreen resolution issues

hi, What about VGA_RAM_SIZE in qemu/hw/pc.h? I already tried changing the VGA_RAM_SIZE value in pc.h to 16 * 1024 * 1024 (16MB), but then kvm crashes when the guest os switches to graphics mode. Changing VGA_RAM_SIZE in pc.h to 16MB works when I use the latest cvs snapshot of qemu (didn't

Re: [kvm-devel] vmwarevga doesn't work: get_dirty_pages returned -2

hi, Most likely it only works with Linux; it was probably written by reverse-engineering the Linux driver. actually -vmwarevga works for me when using pure qemu (latest cvs snapshot) without kqemu (-no-kqemu), but it does not work with kvm when using -no-kvm. anyway, I was testing

Re: [kvm-devel] [PATCH] fix widescreen resolution issues

hi, D'oh. Must have missed it. :\ Thanks! Unfortunately, it still does not work. Qemu crashes now as windows switches to graphics mode. Safe mode does not work either.. For now I'd suggest trying the following: * download the latest qemu cvs snapshot cvs -z3 -d:pserver:[EMAIL

Re: [kvm-devel] [PATCH] fix widescreen resolution issues

hi, * copy the modified vgabios.bin to the qemu dir wget http://www.wina.at/vgabios.bin # cp vgabios.bin /usr/local/qemu-cvs/share/qemu (as root; change to target path according to the prefix you used above) I'm guess I've uploaded to wrong vgabios.bin, so if you don't want to compile it

[kvm-devel] [PATCH] fix widescreen resolution issues (v2)

hi, I found out what crashed kvm when I increased VGA_RAM_SIZE in pc.h. The crash was caused by a really _dirty_ hack in a kvm specific part of vga.c (it took me at least an hour to find this amazing piece of code... at least the HACK ALERT was a good hint ;-) ). I've attached the patch. It

Re: [kvm-devel] Widescreen troubles again -- solved

hi, I managed to get kvm-61 working at a resolution of 1680x1050 (using -std-vga; windowed as well as fullscreen) with windows xp as guest os. Basically I took the following steps: * increase vga memory from 8MB to 16MB (in vbetables-gen.c) * add modes to vbetables-gen.c * change

[kvm-devel] [PATCH] fix widescreen resolution issues

hi, the attached patch fixes the issues with widescreen resolutions for me when using -std-vga. in vgabios/vbetables-gen.c I changed the video memory from 8MB to 16MB which is sufficient for resolutions up to 2560x1600. I've also added some more video modes (up to 2560x1600) with 16, 24,

Re: [kvm-devel] Widescreen troubles again

hi, After that, I called make which correctly updated vbemodes.h and compiled the bios. I then copied the bios to /usr/share/kvm and /usr/share/qemu. well, I think it is very unlikely that the vgabios is located at /usr/share/kvm or so. if you are unsure do a locate vgabios.bin. I've

Re: [kvm-devel] Visual bug in kvm-60 and 61

hi, When moving my mouse slowly upwards the lowest black pixels are not erased. The attached screenshot shows the effect. I've also seen this effect on kvm-61 but it is new for me, I didn't see it on older kvm versions. I tracked it down a litte bit further: * I don't see this effect at all

[kvm-devel] bug/typo in vbetables-gen.c?

hi, is there a specific reason why the 1280x960 resolutions have two mode numbers (one being an exact duplicate of the other) in vbetables-gen.c (0x180 = 0x182, 0x181 = 0x183, see below)? ... { 1280, 960, 24 , 0x180}, { 1280, 960, 32 , 0x181}, { 1280,

Re: [kvm-devel] Widescreen troubles again

hi, I contacted the author of the VBEMP driver. He wrote me that there exist several methods of requesting the available modes from the BIOS. Apparently, by adding a mode to the vbetables-gen.c it's only added to parts of the tables and not to all of them, which is incorrect. By only using

[kvm-devel] vmwarevga doesn't work: get_dirty_pages returned -2

hi, I tried using the -vmwarevga switch but I didn't succeed. I've tested it with kvm-snapshot-20080218, kvm-60 and kvm-61. as soon as the VM (guest os is windows xp) switches from text mode to graphics mode lots of messages kvm: get_dirty_pages returned -2 scroll by on the console. after a
