The Mac binary is probably the same code base as the Linux one. Running Windows binary with wine does not experience this problem, unfortunately wine can only launch this game on MacOS, not FreeBSD. I assume USB can generate higher rate of interrupts than a PS/2 which this game (*nix version) was probably designed for initially. > > --HPS > ___ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
lldb 6.0.0 segfaults on opening a core file
Hi, Running on -CURRENT @ Jan 20 with llvm 6.0.0, I have the following issue opening a core file with lldb: $ lldb /usr/local/bin/python2.7 -c /tmp/python2.7_90218_0.core (lldb) target create "/usr/local/bin/python2.7" --core "/tmp/python2.7_90218_0.core" Assertion failed: (template_counter >= 0), function ConsumeTemplateArgs, file /usr/src/contrib/llvm/tools/lldb/source/Plugins/Language/CPlusPlus/CPlusPlusNameParser.cpp, line 245. This nothing happens for a couple of minutes and then it dumps core. Interestingly though, it can open its own core: %> lldb /usr/bin/lldb -c /tmp/lldb_1129_0.core (lldb) target create "/usr/bin/lldb" --core "/tmp/lldb_1129_0.core" Core file '/tmp/lldb_1129_0.core' (x86_64) was loaded.

Thanx for FreeBSD-CURRENT team! FYI, I believe that you had hit the bug fixed in r327924; sorry about that.

Re: Periodical interrupt storm when playing game with USB keyboard
Hi Yeah the timers eventually get coalesced unless someone's asking for a ridciulously accurate timer value. So is some driver asking for hyper-accurate callout timer that isn't being coalesced? hps, is there any useful debugging to try and find callouts that are requesting stupidly accurate timers? Maybe a dtrace probe on the callout schedule entry point? -adrian ___ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"

I used SDL in the past for android apps and the code is very Linux specific. I am sure there's some Linux related timers in there somewhere that FreeBSD is returning nothing from and that's what's killing the performance. I can almost guarantee that none of the SDL designers and or programmers use any *BSD systems. The easiest solution would be to go look at the timer code and implement something that FreeBSD can work with and try to get that upstream. These are just a few of the issues that will crop up when devs try to just use shims to hook into the Linux kernel. Do the design work up front and implement things in a native way or enjoy the jank. DTrace should be able to point you in the right direction relatively quickly.
