From mboxrd@z Thu Jan 1 00:00:00 1970 From: William Lee Irwin III Date: Sun, 15 Feb 2004 10:04:05 +0000 Subject: 2.4 & Solaris work SMP, 2.6 gets RED_state in prom_startcpu() Message-Id: <20040215100405.GA631@holomorphy.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: sparclinux@vger.kernel.org The RED_state exception goes away when the SMP trampoline is stubbed out (just before flushw) with a nop loop, so this pretty much narrows it down to an exception taken on secondary of some kind before the trampoline code is prepared to recover from it (TLB miss?). The thing appears to deadlock when the secondaries spin like that, but it doesn't go down in flames. Reminder of working things matrix for the box I'm futzing with: Solaris SMP 2.4 UP and SMP with native builds, UP only with crossbuilds 2.6 UP with native builds only, forgot if 2.6 UP with crossbuilds works Ultra2, 2x296MHz, 256MB RAM -- wli
