<0> keithp: hi Keith, mind if I ask some more dumb questions?
<1> rusty: of course; we live to serve our kernel overlords
<0> keithp: I was a little surprised to discover that MIT-SHM doesn't actually map the actual framebuffer, and you still need to call XShmPutImage...
<0> keithp: but I guess this reduces the overhead from IPC + copy to just copy?
<1> rusty: it also eliminates a pair of copies from user->kernel->user
<1> so you move from three copies to one
<1> you can't map the frame buffer; making that visible to applications would be 'bad'
<1> although, I will note that DRI does, so if you want more speed...
<0> keithp: hmmm... Not sure I need it, but it's always nice to have. OTOH anything that uses DRI seems to increase frequency of crashes.
<1> indeed. we need to improve DRI quality a lot
<0> keithp: OK, well I think I'll stick with shm and fallback until someone complains about speed... if I have info on what's actually changed I can avoid putimaging the entire image I guess.
<1> yeah, always a good plan
<0> keithp: ok, next dumb q: does X have man pages for this stuff?
<1> I think so...
<1> but, I can't find them...
<0> keithp: right, I should start reading headers then...
<1> sadly, looks like shm is not in man pages
<0> keithp: Hey, SCO have one! http://uw714doc.sco.com/en/man/html.X3xext/XShm.X3xext.html Can we steal it?
<2> Xorg already got man pages for XShm donated by Sun for 7.2
<2> reminds me, I need to do a libXext release
<3> keithp: so, you heard about the ugly little issue with the damage extension bump I did?
<2> http://gitweb.freedesktop.org/?p=xorg/lib/libXext.git;a=history;f=man/XShm.man
<0> keithp: Hmm, that MIT-SHM paper "Formatted and edited for release 5 by Keith Packard"... is that author Jon Corbet the lwn JC?
<1> alanc: I even looked in the source; is it recently added?
<2> Date: Tue Oct 24 17:14:02 2006 -0700
<2> building tarballs now for it
<1> heh
<1> rusty: must be; he used to work at ncar
<0> keithp: wow... I swear there are 200 people writing all the code in the world.
<1> that was rather a long time ago though
<1> rusty: I think your estimate is generous
<4> hola a todos
<5> hello
<5> is here somebody who can update the www pages of the ewmh spec? it's rather outdated compared to what's in icccm-extensions/wm-spec
<6> any ops around? did someone change something with the apache/php config on annarchy?
<6> ok
<6> so
<6> SOMEONE WAKE UP
<6> because /var is full on annarchy
<6> and it breaks like, everything
<7> dobey: I pinged thomasvs
<8> fyi, moving stuff out of /var on annarchy atm
<6> thomasbe: thanks
