[PATCH] qcap: fix recent regression that limited Wine's v4l2 support to devices that read()
by Damjan Jovanovic 20 Apr '19

20 Apr '19

Recent changes to qcap/v4l.c resulted in the removal of mmap() for v4l2 devices, but read() is optional for device drivers and some don't support it. This isn't a major problem with the presense of libv4l2 though, as it can emulate read() on top of mmap(). However the code checks whether the device can read(), and if not, doesn't even try to use it, even though it can. Fix this by only warning that read() is being emulated, and continuing with libv4l2 if available. Also clarifies the logging.

[PATCH] wineserver: inotify cleanups and detection improvements
by Damjan Jovanovic 20 Apr '19

20 Apr '19

Outside Linux, wineserver fails to link when sys/inotify.h is present, as it tries to find inotify symbols in libc, which doesn't have them. The inotify symbols are in libinotify.so. Detect it properly, and link to it where available. Also clean up usage of inotify on Linux/i386. It shouldn't need to redefine everything, the header was available in sys/inotify.h for a long time now. Does not regenerate "configure".
