- [Qemu-devel] [PATCH 01/14] Add a configure switch to enable / disable all user targets. I felt compelled to do it for symmetry, mostly it is useful to disable user targets when you don't want to build them., (continued)
- [Qemu-devel] [PATCH 01/14] Add a configure switch to enable / disable all user targets. I felt compelled to do it for symmetry, mostly it is useful to disable user targets when you don't want to build them., Zachary Amsden, 2009/07/30
- [Qemu-devel] [PATCH 02/14] Don't segfault when changing VNC password on an SDL display., Zachary Amsden, 2009/07/30
- [Qemu-devel] [PATCH 03/14] When using stdio monitor and VNC display, one can set or clear a VNC password; this should set or turn off VNC authentication as well., Zachary Amsden, 2009/07/30
- [Qemu-devel] [PATCH 04/14] Clean up VGA type selection; far too many variables being used to track one state leads to confusion if new variables are added., Zachary Amsden, 2009/07/30
- [Qemu-devel] [PATCH 05/14] Change cpu_phys mem callback to use [offset, size) bounds instead of [start, end)., Zachary Amsden, 2009/07/30
- [Qemu-devel] [PATCH 06/14] Split VGA ioport init into a helper function., Zachary Amsden, 2009/07/30
- [Qemu-devel] [PATCH 07/14] Code motion; make mm VGA init function more like standard vga init function. Add missing vga_reset hook to vga_mm_init., Zachary Amsden, 2009/07/30
- [Qemu-devel] [PATCH 08/14] Make VGA vram offset passed into vga_mm_init absolute. Since this is a function of the platform, it makes sense to have it be explicitly known in the platform layer rather than hardcoded inside the vga code., Zachary Amsden, 2009/07/30
- [Qemu-devel] [PATCH 09/14] Further transformation: use common vga_init() which allows either I/O port or memory mapped based control., Zachary Amsden, 2009/07/30
- [Qemu-devel] [PATCH 10/14] Stash VGA physical address and use it in KVM callbacks. Stash VGA physical pointer in cirrus vga as well., Zachary Amsden, 2009/07/30
- [Qemu-devel] [PATCH 11/14] Add some defined constants for VGA offsets.,
Zachary Amsden <=
- [Qemu-devel] [PATCH 12/14] Add a PCI BAR for the VGA ROM which is mapped into cirrus_vga. This makes the cirrus device complete under some X servers which require the V_BIOS mapping., Zachary Amsden, 2009/07/30
- [Qemu-devel] [PATCH 13/14] Allow cirrus VGA to be initialized multiple times; only the first init takes the ISA memory region and hardware I/O ports., Zachary Amsden, 2009/07/30
- [Qemu-devel] [PATCH 14/14] Atrocious and horrendous patch to demonstrate multiple SDL displays. The multiple SDL displays can be seen on one console, using ctrl-alt-1/2 to switch between them., Zachary Amsden, 2009/07/30
