2022-06-06modules: introduces module_kconfig directiveJose R. Ziviani
module_kconfig is a new directive that should be used with module_obj whenever that module depends on the Kconfig to be enabled. When the module is enabled in Kconfig we are sure that its dependencies will be enabled as well, thus the module will be loaded without any problem. The correct way to use module_kconfig is by passing the Kconfig option to module_kconfig (or the *config-devices.mak without CONFIG_). Signed-off-by: Jose R.

2022-04-06Replace config-time define HOST_WORDS_BIGENDIANMarc-André Lureau
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.

2021-07-22hw/display: fix virgl reset regressionMarc-André Lureau
Before commit 49afbca3b00e8e517d54964229a794b51768deaf ("virtio-gpu: drop use_virgl_renderer"), use_virgl_renderer was preventing calling GL functions from non-GL context threads. The innocuously looking g->parent_obj.use_virgl_renderer = false; was set the first time virtio_gpu_gl_reset() was called, during pc_machine_reset() in the main thread. Further virtio_gpu_gl_reset() calls in IO threads, without associated GL context, were thus skipping GL calls and avoided warnings or crashes (see also https://gitlab.freedesktop.org/virgl/virglrenderer/-/issues/226).

2021-07-22hw/display: fail early when multiple virgl devices are requestedMarc-André Lureau
This avoids failing to initialize virgl and crashing later on, and clear the user expectations.

Move two virglrenderer state variables to struct VirtIOGPUGL. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Message-id: 20210430113547.1816178-1-kraxel@redhat.com Message-Id: <20210430113547.1816178-14-kraxel@redhat.com>
2021-05-10virtio-gpu: drop use_virgl_rendererGerd Hoffmann
Now that we have separated the gl and non-gl code flows to two different devices there is little reason turn on and off virglrenderer usage at runtime. The gl code can simply use virglrenderer unconditionally. So drop use_virgl_renderer field and just do that.

2021-05-10virtio-gpu: move virgl realize + propertiesGerd Hoffmann
Move device init (realize) and properties. Drop the virgl property, the virtio-gpu-gl-device has virgl enabled no matter what. Just use virtio-gpu-device instead if you don't want enable virgl and opengl. This simplifies the logic and reduces the test matrix.
