Modified files: sys/boot/i386/btx/btx btx.S Log: SVN rev 181433 on 2008-08-08 19:39:11Z by jhb Fix the hangs reported with the real mode BTX: - I had errantly assumed that all user requests should run with interrupts enabled. User requests for software interrupts, however, need to disable interrupts (and tracing) just like hardware interrupts. - Disable alignment checking when emulating a hardware interrupt as well (based on the description of the real mode operation of the 'INT' instruction in the IA-32 manuals). - Use constants for fields in %eflags. Tested by: bz MFC after: 3 days Revision Changes Path 1.47 +22 -11 src/sys/boot/i386/btx/btx/btx.S _______________________________________________ cvs-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/cvs-all To unsubscribe, send any mail to "[EMAIL PROTECTED]"
