Still disabled like on i386. Lock the apic with a mutex, not a SIMPLE_LOCK. 2005-05-31T09:34:22Z art art@openbsd.org 2005-05-31T09:34:22Z urn:sha1:7dc76f73715c8b2b0dced4e78794d1950214cc1b markus@ ok miod@ tried to ok, but he doesn't officially have an amd64. sched work by niklas and art backed out; causes panics 2005-05-29T03:20:35Z deraadt deraadt@openbsd.org 2005-05-29T03:20:35Z urn:sha1:5bc652b1fc0fb53fbffea9975a1786d7967bb900 This patch is mortly art's work and was done *a year* ago.

I am sorry. Change the sched_lock to a mutex. This fixes, among other things, the infamous "telnet localhost &" problem. The real bug in that case was that the sched_lock which is by design a non-recursive lock, was recursively acquired, and not enough releases made us hold the lock in the idle loop, blocking scheduling on the other processors. Some of the other processors would hold the biglock though, which made it impossible for cpu 0 to enter the kernel... A nice deadlock. Let me just say debugging this for days just to realize that it was all fixed in an old diff noone ever ok'd was somewhat of an anti-climax. This diff also changes splsched to be correct for all our architectures. SMP support. Big parts from NetBSD, but with some really serious debugging 2004-06-25T11:03:27Z art art@openbsd.org 2004-06-25T11:03:27Z urn:sha1:b5b9857b3f6cd71d5c36ee5aa4b167d1128157a3 done by me, niklas and others. Especially wrt. NXE support. Still needs some polishing, especially in dmesg messages, but we're now building kernel faster than ever. an amd64 arch support. 2004-01-28T01:39:38Z mickey mickey@openbsd.org 2004-01-28T01:39:38Z urn:sha1:f5df1827e930693b77256fbf32ab5050c01d960c hacked by art@ from netbsd sources and then later debugged by me into the shape where it can host itself. no bootloader yet as needs redoing from the recent advanced i386 sources (anyone? ;)
