From 5d56aa9cb2bdbe0a18bafbdbb6eb8cf6a46beb79 Mon Sep 17 00:00:00 2001 From: deischen Date: Fri, 18 Apr 2003 05:04:16 +0000 Subject: Revamp libpthread so that it has a chance of working in an SMP environment. This includes support for multiple KSEs and KSEGs. The ability to create more than 1 KSE via pthread_setconcurrency() is in the works as well as support for PTHREAD_SCOPE_SYSTEM threads. Those should come shortly. There are still some known issues which davidxu and I are working on, but it'll make it easier for us by committing what we have. This library now passes all of the ACE tests that libc_r passes with the exception of one. It also seems to work OK with KDE including konqueror, kwrite, etc. I haven't been able to get mozilla to run due to lack of java plugin, so I'd be interested to see how it works with that.
