2018-05-07qxl: fix local renderer crashGerd Hoffmann1-1/+2
Make sure we only ask the spice local renderer for display updates in case we have a valid primary surface. Without that spice is confused and throws errors in case a display update request (triggered by screendump for example) happens in parallel to a mode switch and hits the race window where the old primary surface is gone and the new isn't establisted yet.

Replace all occurs of __FUNCTION__ except for the check in checkpatch with the non GCC specific __func__. One line in hcd-musb.c was manually tweaked to pass checkpatch.

2017-09-01qxl: drop mono cursor supportGerd Hoffmann1-9/+0
The chunk size sanity check in qxl_render_cursor works for SPICE_CURSOR_TYPE_ALPHA cursors only. So support for SPICE_CURSOR_TYPE_MONO cursors must be broken for ages without anyone noticing. Most likely it simply isn't used any more by guest drivers. Drop the dead code. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Message-id: 20170828123933.30323-2-kraxel@redhat.com

2014-12-16spice: use bottom half instead of refresh timer for cursor updatesGerd Hoffmann1-0/+2
Calling directly doesn't work due to the qxl-render code running in spice server thread context. Meanwhile bottom half scheduling is thread-safe though, so we can use that to kick a cursor update in main i/o thread context.

2014-09-05console: stop using PixelFormatGerd Hoffmann1-3/+4
With this patch the qemu console core stops using PixelFormat and pixman format codes side-by-side, pixman format code is the primary way to specify the DisplaySurface format: * DisplaySurface stops carrying a PixelFormat field. * qemu_create_displaysurface_from() expects a pixman format now. Functions to convert PixelFormat to pixman_format_code_t (and back) exist for those who still use PixelFormat. As PixelFormat allows easy access to masks and shifts it will probably continue to exist. [ xenfb added by Benjamin Herrenschmidt ] Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2014-09-01qxl-render: add more sanity checksGerd Hoffmann1-1/+3
Damn, the dirty rectangle values are signed integers. So the checks added by commit 788fbf042fc6d5aaeab56757e6dad622ac5f0c21 are not good enough, we also have to make sure they are not negative. [ Note: There must be something broken in spice-server so we get negative values in the first place.

2013-09-10qxl: fix local rendererGerd Hoffmann1-5/+10
The local spice renderer assumes the primary surface is located at the start of the "ram" bar. This used to be a requirement in qxl hardware revision 1. In revision 2+ this is relaxed. Nevertheless guest drivers continued to use the traditional location, for historical and backward compatibility reasons. The qxl kms driver doesn't though as it depends on qxl revision 4+ anyway. Result is that local rendering is hosed for recent linux guests, you'll get pixel garbage with non-spice ui (gtk, sdl, vnc) and when doing screendumps. Fix that by doing a proper mapping of the guest-specified memory location. https://bugzilla.redhat.com/show_bug.cgi?id=948717 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
