2024-10-14ui: refactor using a common qemu_pixman_shareableMarc-André Lureau1-1/+23
Use a common shareable type for win32 & unix, and helper functions. This simplify the code as it avoids a lot of #ifdef'ery. Note: if it helps review, commits could be reordered to introduce the common type before introducing shareable memory for unix.

2024-10-14ui/win32: fix potential use-after-free with dbus shared memoryMarc-André Lureau1-0/+2
DisplaySurface may be free before the pixman image is freed, since the image is refcounted and used by different objects, including pending dbus messages. Furthermore, setting the destroy function in create_displaysurface_from() isn't appropriate, as it may not be used, and may be overriden as in ramfb. Set the destroy function when the shared handle is set, use the HANDLE directly for destroy data, using a single common helper qemu_pixman_win32_image_destroy().

2023-11-07ui: add pixman-minimal.hMarc-André Lureau1-0/+2
This is a tiny subset of PIXMAN API that is used pervasively in QEMU codebase to manage images and identify the underlying format. It doesn't seems worth to wrap this in a QEMU-specific API. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Acked-by: Thomas Huth <thuth@redhat.com>

Android uses XBGR8888 and ABGR8888 as default scanout buffer, But qemu does not support them for qemu_pixman_to_drm_format conversion within virtio_gpu_create_dmabuf for virtio gpu. so, add those 2 formats into drm_format_pixman_map.

2023-09-04ui/console: use QEMU_PIXMAN_COLOR helpersMarc-André Lureau1-0/+6
QEMU_RGB macro is actually defining a pixman color. Make this explicit in the macro name. Move it to qemu-pixman.h so it can be used elsewhere, as done in the following patch. Finally, define QEMU_PIXMAN_COLOR_{BLACK,GRAY}, to avoid need to look up the VGA color table from the QemuConsole placeholder surface rendering.

2022-04-06Replace config-time define HOST_WORDS_BIGENDIANMarc-André Lureau1-1/+1
Replace a config-time define with a compile time condition define (compatible with clang and gcc) that must be declared prior to its usage. This avoids having a global configure time define, but also prevents from bad usage, if the config header wasn't included before. This can help to make some code independent from qemu too. gcc supports __BYTE_ORDER__ from about 4.6 and clang from 3.2.

2020-07-13Remove the CONFIG_PRAGMA_DIAGNOSTIC_AVAILABLE switchThomas Huth1-4/+0
GCC supports "#pragma GCC diagnostic" since version 4.6, and Clang seems to support it, too, since its early versions 3.x. That means that our minimum required compiler versions all support this pragma already and we can remove the test from configure and all the related #ifdefs in the code. Reviewed-by: Daniel P.
