Thanks for talking with me about it first. *sigh* I thought I had said something when I replied to the initial commit, but looking back at the archives I didn't say anything specific to IPI_HALT. The short version is that with IPI_HALT the 4100 here at work always hung. When I tried to add in a handshake to transfer things over to the boot cpu to fix that I found that every shutdown resulted in a reboot, even shutdown -h, which resulted in discovering the bug in prom_halt() (After which I pulled out the brown book and hunted down the section I mentioned to verify.) I can back this out if you prefer. I should have said something earlier however, or at least ran the patch by you first. > On Mon, 13 Aug 2001, John Baldwin wrote: > >> jhb 2001/08/13 15:41:15 PDT >> >> Modified files: >> sys/alpha/alpha machdep.c mp_machdep.c vm_machdep.c >> sys/alpha/include smp.h >> Log: >> Remove IPI_HALT to make way for a more correct fix for halts and restarts >> on SMP alphas. >> >> Revision Changes Path >> 1.138 +1 -9 src/sys/alpha/alpha/machdep.c >> 1.26 +1 -4 src/sys/alpha/alpha/mp_machdep.c >> 1.57 +1 -12 src/sys/alpha/alpha/vm_machdep.c >> 1.6 +1 -2 src/sys/alpha/include/smp.h >> >> > -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
