[PATCH] Enable VGA output when setting Cirrus-specific mode
by Laszlo Ersek 18 Feb '13

18 Feb '13

This patch does the same for Cirrus as David's following patch for bochs, originally posted under <http://www.seabios.org/pipermail/seabios/2013-February/005434.html>: Enable VGA output when settings bochs-specific mode When used from OVMF+CSM, we got no video output. It appears that we were never enabling the display output except when configuring a text mode. Which never happens, in the OVMF+CSM case. In my testing on RHEL-6.3 with OVMF -D CSM_ENABLE / CONFIG_CSM bios.bin / CONFIG_QEMU vgabios.bin, using Cirrus, VESA mode 0x115 is selected (Direct Color, 800x600x24). According to <http://www.osdever.net/FreeVGA/vga/attrreg.htm>, cirrus_switch_mode() stdvga_attr_mask() currently keeps/sets the "Attribute Controller Graphics Enable" bit set in the "Attribute Mode Control Register". When invoked from OVMF+CSM, that is not enough however, so let's do the same as for Bochs: stdvga_attrindex_write(0x20); which corresponds to setting the "Palette Address Source" bit in the "Attribute Address Register": "This bit is set to 0 to load color values to the registers in the internal palette. It is set to 1 for normal operation of the attribute controller. [...]" clext_set_mode() stdvga_set_mode() -- for regular modes stdvga_attrindex_write() -- existing call cirrus_switch_mode() -- for Cirrus modes stdvga_attrindex_write() -- call added by this patch Signed-off-by: Laszlo Ersek <lersek(a)redhat.com> --- My motivation for using Cirrus instead of stdvga is three-fold: - using libvirt on RHEL-6.3, Cirrus seems to be the default video card for the guests I tend to create, - it provides better max resolution in the Fedora 18 guest, - for some reason (maybe due to kernel build options?) the Fedora 18 guest can't display character mode consoles on stdvga, but works well with Cirrus. (F18/Xorg/{stdvga,cirrus} are OK, and so are RHEL6/{Xorg,console}/{stdvga,cirrus}.)

[PATCH] Clarify build generated "zone low" values.

Rename datalow_base (and similar) to zonelow_base, and datalow_start (and similar) to varlow_start.
