Correct the UV2 broacast assist unit's destination timeout period. And the activation status register in UV2 should be tested for a destination timeout with a 4, not a 2. The values for Active versus Timeout were reversed. This patch is critical for TLB shootdown on an Altix UV2 system (i.e. the follow-on to the current Altix UV). Destination timeout period: The period is set in 4 bits of memory-mapped register MISC_CONTROL. The left bit toggles base period between 10us and 80us. The other 3 bits are the multiplier. Decimal 15, hex f, gives the maximum: 7 * 80us Signed-off-by: Cliff Wickman <cpw@sgi.com> Link: http://lkml.kernel.org/r/20110621122243.117324443@sgi.com Signed-off-by: Ingo Molnar <mingo@elte.hu> |
