Just FYI: GeForce 7800 GT on a PowerMac Quad-core G5 with a 1920x1200 display: [mi] EQ overflowing

[Mark Millard]

Hi.

I've now had this EQ overflowing notice with a 1920x1200 display on the GeForce 7800 GT.

I'll note that I've updated to ports r368074 which updated Xorg, the drivers, and even gcc (to 4.8.3). This was on...

FreeBSD FBSDG4S0 10.1-PRERELEASE FreeBSD 10.1-PRERELEASE #0 r271215: Sat Sep  6 23:56:15 PDT 2014     root at FBSDG4S0:/usr/obj/usr/src/sys/GENERIC  powerpc

but booted on a G5 PowerMac quad-core (so lots of unused RAM for powerpc/GENERIC).

[mi] mieq is *NOT* the cause.  It is a victim.
[mi] Increasing EQ size to 512 to prevent dropped events.

[mi] This may be caused my a misbehaving driver monopolizing the server's resources.

Context:

I built a 10.1-PRERELEASE r271215 (to test Justin Hibbits' changes for powerpc). I also used portsnap and then rebuilt my ports from scratch.

(I'd be surprised if this was powerpc or PowerMac specific. But use of these old cards may be more likely for PCI-Express PowerMacs.)
