* qxl_dev.h: add client monitors configuration notification to guestAlon Levy2012-09-121-0/+16
| | | | | | | | | | | | | | | | | | | | | | | So far we have used the agent to notify the guest of a request to change the monitors configurations (heads) on the qxl device. This patch introduces a new interrupt and new fields in the qxl rom to notify the guest about a new request, similarly to how physical hardware notifies the driver. We compute crc over the monitors configuration to avoid host-write from a following update while guest-read corruption. The update protocol is: qemu: (2) fill QXLRom::client_monitors_config (3) raise QXL_INTERRUPT_CLIENT_MONITORS_CONFIG guest: (1) clear QXL_INTERRUPT_CLIENT_MONITORS_CONFIG bit in irq status (2) read QXLRom::client_monitors_config (3) (verify-crc)? done : goto 2 If the interrupt mask is ~0 or 0, or does not have QXL_INTERRUPT_CLIENT_MONITORS_CONFIG set, we also assume it doesn't support this interrupt.
* Add new client_present and client capabilities fields to QXLRomSøren Sandmann Pedersen2012-09-021-1/+4
| | | | | | | | | | | | | | | | The client_present field is a byte that is set of non-zero when a client is connected and to zero when no client is connected. The client_capabilities[58] array contains 464 bits that indicate the capabilities of the client. Each bit corresponds to a SPICE_DISPLAY_CAP_* capability. In particular, if the client has capability C, then bit (C % 8) in byte (C / 8) is set. The capability bits only have a defined meaning when a client is connected, ie., when client_present is non-zero. The number 58 was chosen to fill out a cache line in QXLRom. A new QXL_INTERRUPT_CLIENT interrupt is defined, which will be raised whenever a client connects or disconnects.
* Add support for QXLComposite to the Spice protocol headersSøren Sandmann Pedersen2012-08-221-0/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This new command is intended to be used for implementing the Composite request from the Render X extension. See http://www.x.org/releases/current/doc/renderproto/renderproto.txt for a description of the Render extension. Composite has three fields: src, mask and destination, of which mask is optional (can be NULL). There are also two pointers to transformations, one for each of src and mask. The command also has 32 bits of flags which indicates - which compositing operator to use - which filters to apply when sampling source and mask - which repeat mode to apply when sampling source and mask - whether the mask should be considered to have 'component alpha' - whether the alpha channel of any of the images should be ignored. The last one of these features is necessary because in the X protocol an offscreen surface is simply a collection of bits with no visual interpretation. In order for Render to use these bits, a wrapper object is used that contains the pixel format. Since one offscreen surface can be wrapped by multple objects, there is not a one-to-one correspondence between pixel formats and surfaces. In SPICE surfaces do have an associated pixel format, which means the above feature of Render cannot be supported without adding a similar concept to the wrapper object to the SPICE protocol. However, the most common use for having multiple wrappers for one offscreen surface is to interpret an alpha surface as not having an alpha channel or vice versa.
* support multiple monitors on a single display channelAlon Levy2012-06-271-1/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds on device: RAM Header monitors_config - pointer QXLMonitorsConfig count == n max_allowed = N >= 0 QXLHead 1 ... QXLHead n id, surface_id, x, y, width, height, flags IO: QXL_IO_MONITORS_CONFIG server flushes command ring, then calls server callback for changing monitors config. New revision to let the driver know about the new io: QXL_REVISION_STABLE_V12=0x04, Adds server/client capability: SPICE_DISPLAY_CAP_MONITORS_CONFIG Server message will be added in spice-server and spice-common. Version is bumped to 0.12.0 to indicate new IO and structs
* qxl_dev: fix const cast warning for QXL_R[AO]M_MAGICAlon Levy2012-04-091-2/+2

* qxl_dev: add third revision V10Alon Levy2011-07-171-2/+6
| | | | | The driver will check for this revision or higher to know that the device supports async io, the two S3 related ios, and the interrupts IO_CMD and ERROR.
* qxl_dev: add QXL_INTERRUPT_ERRORAlon Levy2011-07-171-0/+1
| | | | | The interrupt is used to notify the guest driver it did an error in the last io operation. It can be left unhandled.
* add QXL_IO_FLUSH_{SURFACES,RELEASE} for sleep (S3) supportAlon Levy2011-07-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | related RHBZ: 688883 Guest initiated sleep looks like this: Guest: (0) stop putting new commands into the rings (1) QXL_IO_FLUSH_SURFACES qxl calls flush_surfaces(), spice-server flushes command rings and renders all surfaces, thereby flushing state to device memory. (2) QXL_IO_DESTROY_ALL_SURFACES zap surfaces (3) QXL_IO_FLUSH_RELEASE push release queue head into the release ring, so the guest will see it and can release everything. (4) tell acpi to reset Qemu: (5) qxl_reset_handler Guest: (6) sends surface create commands The QXL_IO_FLUSH_SURFACES is an optimization, to reduce vmexits. It is used to flush both command rings and update all surfaces at once (equivalent to UPDATE_AREA X NUM_ACTIVE_SURFACES) destroy all surfaces to release resources but not destroy the guest side surfaces get device to flush all server released resources to the release ring (could use multiple calls to OOM - but this is not well defined, would need to loop) After (1) there will be no memory allocated on the pci bars.

* add compat flag for 16bpp modeGerd Hoffmann2010-09-141-1/+2
| | | | | | | | | | spice 0.6 uses 32bpp values unconditionally for brush and palette colors. spice 0.4 used to use 16 bpp or 32 bpp depending on the video mode. The qxl parser needs to know the guest video mode depth to correctly interpret these values in spice 0.4 compat mode. Add a flag to pass on this informartion.

* make unstable qxl compatible with 0.4 qxlGerd Hoffmann2010-04-261-3/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add SET_MODE IO port back in. Add QXLRom offset fields back in. I/O ports, RAM and ROM layout are binary compatible now. With these changes merged it should be possible to create *one* qxl device which supports *both* 0.4 and unstable spice commands. Everything the guest touches before entering native mode is binary compatible. Old (0.4) guests drivers enter native mode via SET_MODE, new (unstqable) guest drivers enter native mode using CREATE_PRIMARY, so when we see spice commands from the guest come in we know whenever we have to interpret them as 0.4 or unstable ones. Added commends to structs which need care wrt. compatibility when updating. Added some QXLCompat* structs for the 0.4 struct versions. Added a flags field to QXLCommandEx so qxl can signal whenever commands are compat or not. Moved QXLRom->n_surfaces to make QXLRom->flags 64bit aligned. Add padding to QXLRom to ensure future elements are 32bit aligned. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
