Experimental fork of QEMU with video encoding patches https://git.openslx.org/bwlp/qemu.git/atom/tcg/tci?h=spice_video_codecs 2022-07-05T10:47:53+00:00 2022-07-05T10:47:53+00:00 Richard Henderson 2022-07-05T08:33:13+00:00 urn:sha1:0df0a6655522f9a9df78aeab39a96f2d0f181c92 There is nothing in this environment variable that cannot be done better with -d flags. There is nothing special about TCI that warrants this hack. Moreover, it does not compile -- remove it.
