Tom	38af4c29e6	WindowServer: Coalesce flushing buffers into one ioctl() call ... We regularily need to flush many rectangles, so instead of making many expensive ioctl() calls to the framebuffer driver, collect the rectangles and only make one call. And if we have too many rectangles then it may be cheaper to just update the entire region, in which case we simply convert them all into a union and just flush that one rectangle instead.	2021-06-27 09:46:27 +02:00
Tom	56cd0f929e	Kernel: Enable additional VirtIO displays only on first resolution set ... Also, only allocate the amount of memory we actually need for the given resolution.	2021-06-27 09:46:27 +02:00
Tom	8749235046	Kernel: Add support for multiple VirtIO GPU outputs ... This creates /dev/fbX devices for each physical output, owned by the parent VirtIOGPU instance. This allows mapping and setting resolutions independently for each output.	2021-06-27 09:46:27 +02:00
