extern

gpu_is_edid_supported – returns if edid blob is supported by host

Returns
true if supported, false if not supported

◆ gpu_is_virgl_supported()

bool gpu_is_virgl_supported ( )
extern

gpu_is_virgl_supported – returns if virgl is supported by host

Returns
true if supported, false if not supported

◆ virt_gpu_default_resource_id()

int virt_gpu_default_resource_id ( )
extern

virt_gpu_default_resource_id – resource id of the scanout created at driver init (the one the console mirror presents to)

◆ VirtGpuConsolePresent()

AU_EXTERN AU_EXPORT void VirtGpuConsolePresent ( uint32_t *  src,
uint32_t  src_pitch,
int  x,
int  y,
int  w,
int  h 
)

VirtGpuConsolePresent – copy a console damage rect into the scanout backing and transfer+flush exactly that rect. Installed as the kernel console present hook; aucon only calls it while no compositor owns the display. Exported: under this toolchain AU_EXPORT is the only thing lld honors for COFF exports, and the kernel resolves the hook by plain name from our export table – an unexported symbol silently never matches (C linkage alone is not enough). –axiss.
