[Qemu-devel] [PATCH 00/13] vga: dirty log cleanup, more linear mapping

[Jan Kiszka <jan.kiszka@siemens.com>]

A few optimizations and cleanups I came across when trying to speed up
slow graphical grub unter non-cirrus vga. This series
 - eliminates log_start/stop CPUPhysMemoryClient callbacks
 - accelerates chain 4 vga mode under KVM
 - fixes reset of vmware-vga
 - cleans up vmware-vga a bit

At least patch 8 is a candiate for 0.15 and stable.

Jan Kiszka (13):
  spice: Use cpu_register_physical_memory_log for dirty log enabling
  vga-pci: Use cpu_register_physical_memory_log for dirty log enabling
  cirrus-vga: Drop redundant vga_dirty_log_start
  vmware-vga: Disable verbose mode
  vmware-vga: Remove dead DIRECT_VRAM mode
  vmware-vga: Eliminate vga_dirty_log_restart
  vmware_vga: Do not enable dirty logging when in SVGA mode
  vmware-vga: Register reset service
  vmware-vga: Use cpu_register_physical_memory_log for dirty log
    enabling
  Drop dirty log start/stop infrastructure
  vga: Refactor lfb_vram_mapped to vga_mem_mapped
  vga: Move vga_sync_dirty_bitmap
  vga: Use linear mapping + dirty logging in chain 4 memory access mode
