2012-02-28qxl: add optinal 64bit vram barGerd Hoffmann1-0/+7
This patch adds an 64bit pci bar for vram. It is turned off by default. It can be enabled by setting the size of the 64bit bar to be larger than the 32bit bar. Both 32bit and 64bit bar refer to the same memory. Only the first part of the memory is available via 32bit bar. The intention is to allow large vram sizes for 64bit guests, by allowing the vram bar being mapped above 4G, so we don't have to squeeze it into the pci I/O window below 4G. With vram_size_mb=16 and vram64_size_mb=256 it looks like this: 00:02.0 VGA compatible controller: Red Hat, Inc. Device 0100 (rev 02) (prog-if 00 [VGA controller]) Subsystem: Red Hat, Inc Device 1100 Physical Slot: 2 Flags: fast devsel, IRQ 10 Memory at f8000000 (32-bit, non-prefetchable) [size=64M] Memory at fc000000 (32-bit, non-prefetchable) [size=16M] Memory at fd020000 (32-bit, non-prefetchable) [size=8K] I/O ports at c5a0 [size=32] Memory at ffe0000000 (64-bit, prefetchable) [size=256M] Expansion ROM at fd000000 [disabled] [size=64K] [ mapping above 4G needs patched seabios: http://www.kraxel.org/cgit/seabios/commit/?h=pci64 ]
2012-02-27qxl: make qxl_render_update asyncAlon Levy1-0/+10
RHBZ# 747011 Removes the last user of QXL_SYNC when using update drivers that use the _ASYNC io ports. The last user is qxl_render_update, it is called both by qxl_hw_update which is the vga_hw_update_ptr passed to graphic_console_init, and by qxl_hw_screen_dump. At the same time the QXLRect area being passed to the red_worker thread is passed as a copy, as part of the QXLCookie. The implementation uses interface_update_area_complete with a bh to make sure dpy_update and qxl_flip are called from the io thread, otherwise the vga->ds->surface.data can change under our feet. With this patch sdl+spice works fine. But spice by itself doesn't produce the expected screendumps unless repeated a few times, due to ppm_save being called before update_area (rendering done in spice server thread) having a chance to complete. Fixed by next patch, but see commit message for problem introduced by it. Signed-off-by: Alon Levy <alevy@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-02-27qxl: remove flippedAlon Levy1-1/+1
Tested on linux and windows guests. For negative stride, qxl_flip copies directly to vga->ds->surface->data, for positive it's reallocated to share qxl->guest_primary.data Signed-off-by: Alon Levy <alevy@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-27qxl: require spice >= 0.8.2Alon Levy1-4/+0
drop all ifdefs on SPICE_INTERFACE_QXL_MINOR >= 1 as a result, any check for SPICE_SERVER_VERSION that is now always satisfied, and SPICE_INTERFACE_CORE_MINOR >= 3 tests, because 0.8.2 has SPICE_INTERFACE_QXL_MINOR == 1 and SPICE_INTERFACE_CORE_MINOR == 3.

2011-11-01qxl: stride fixupGerd Hoffmann1-1/+2
spice uses negative stride value to signal the bitmap is upside down. The qxl renderer (used for scl, vnc and screenshots) wants a positive value because it is easier to work with. The positive value is then stored in the very same variable, which has the drawback that the upside-down test works only once. Fix by using two variables.

2011-10-25qxl: Convert to QEMU thread APIJan Kiszka1-1/+2
Use QEMU thread API instead of pthread directly. We still need to get rid of pthread_yield, though, to drop pthread.h inclusion. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-08-08vga: convert vga and its derivatives to the memory APIAvi Kivity1-3/+3
Convert all vga memory to the memory API. Note we need to fall back to get_system_memory(), since the various buses don't pass the vga window as a memory region. We no longer need to sync the dirty bitmap of the cirrus mapped memory banks, since the memory API takes care of that for us.

2011-08-03qxl: async io support using new spice apiAlon Levy1-3/+13
Some of the QXL port i/o commands are waiting for the spice server to complete certain actions. Add async versions for these commands, so we don't block the vcpu while the spice server processses the command. Instead the qxl device will raise an IRQ when done. The async command processing relies on an added QXLInterface::async_complete and added QXLWorker::*_async additions, in spice server qxl >= 3.1 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Alon Levy <alevy@redhat.com>

2011-08-01qxl: error handling fixes and cleanups.Gerd Hoffmann1-1/+2
Add qxl_guest_bug() function which is supposed to be called in case sanity checks of guest requests fail. It raises an error IRQ and logs a message in case guest debugging is enabled. Make PANIC_ON() abort instead of exit. That macro should be used for qemu bugs only, any guest-triggerable stuff should use the new qxl_guest_bug() function instead. Convert a few easy cases from PANIC_ON() to qxl_guest_bug() to show intended usage. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-08-01qxl: fix surface tracking & lockingGerd Hoffmann1-0/+2
Surface tracking needs proper locking since it is used from vcpu and spice worker threads, add it. Also reset the surface counter when zapping all surfaces. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-08-01spice/qxl: move worker wrappersGerd Hoffmann1-0/+13
Move the wrapper functions which are used by qxl only to qxl.c. Rename them from qemu_spice_* to qxl_spice_*. Also pass in a qxl state pointer instead of a SimpleSpiceDisplay pointer. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-01-24spice/qxl: zap spice 0.4 migration compatibility bitsGerd Hoffmann1-4/+0
Live migration from and to spice 0.4 qxl devices isn't going to work. Rip out the bits which attempt to support that. Zap the subsection logic which is obsolete now. Bumb the version to make a clean cut. This should obviously go in before 0.14 is released. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2010-12-09spice: add qxl deviceGerd Hoffmann1-0/+112
qxl is a paravirtual graphics card. The qxl device is the bridge between the guest and the spice server (aka libspice-server). The spice server will send the rendering commands to the spice client, which will actually render them. The spice server is also able to render locally, which is done in case the guest wants read something from video memory. Local rendering is also used to support display over vnc and sdl. qxl is activated using "-vga qxl". qxl supports multihead, additional cards can be added via '-device qxl".
