2005-06-27[PATCH] cciss: pci id fixMike Miller3-4/+9
This patch fixes a PCI ID I got wrong before. It also adds support for another new SAS controller due out this summer. I didn't have a marketing name prior to my last submission. Also modifies the copyright date range.

mthca apparently had the meanings of the max_rd_atomic and max_dest_rd_atomic QP attributes backwards. max_rd_atomic limits the maximum number of outstanding RDMA/atomic requests as an initiator (on a send queue), and max_dest_rd_atomic specifies the resources allocated to handle RMDA/atomic requests from the remote end of the connection.

2005-06-27[PATCH] seccomp: tsc disableAndrea Arcangeli5-10/+82
I believe at least for seccomp it's worth to turn off the tsc, not just for HT but for the L2 cache too. So it's up to you, either you turn it off completely (which isn't very nice IMHO) or I recommend to apply this below patch. This has been tested successfully on x86-64 against current cogito repository (i686 compiles so I didn't bother testing ;). People selling the cpu through cpushare may appreciate this bit for a peace of mind. There's no way to get any timing info anymore with this applied (gettimeofday is forbidden of course). The seccomp environment is completely deterministic so it can't be allowed to get timing info, it has to be deterministic so in the future I can enable a computing mode that does a parallel computing for each task with server side transparent checkpointing and verification that the output is the same from all the 2/3 seller computers for each task, without the buyer even noticing (for now the verification is left to the buyer client side and there's no checkpointing, since that would require more kernel changes to track the dirty bits but it'll be easy to extend once the basic mode is finished). Eliminating a cold-cache read of the cr4 global variable will save one cacheline during the tlb flush while making the code per-cpu-safe at the same time. Thanks to Mikael Pettersson for noticing the tlb flush wasn't per-cpu-safe. The global tlb flush can run from irq (IPI calling do_flush_tlb_all) but it'll be transparent to the switch_to code since the IPI won't make any change to the cr4 contents from the point of view of the interrupted code and since it's now all per-cpu stuff, it will not race. So no need to disable irqs in switch_to slow path. Signed-off-by: Andrea Arcangeli <andrea@cpushare.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-06-27[PATCH] ppc32: Bump PMU interrupt priorityBenjamin Herrenschmidt3-7/+35
The Power Management Unit on PowerMacs is very sensitive to timeouts during async message exchanges. It uses rather crude protocol based on a shift register with an interrupt and is almost continuously exchanging messages with the host CPU on laptops. This patch adds a routine to the open_pic driver to be able to select a PMU driver so that it bumps it's interrupt priority to above the normal level. This will allow PMU interrupts to occur while another interrupt is pending, and thus reduce the risk of machine beeing abruptly shutdown by the PMU due to a timeout in PMU communication caused by excessive interrupt latency. The problem is very rare, and usually just doesn't happen, but it is still useful to make things even more robust.

2005-06-27[PATCH] 8xx: avoid "dcbst" misbehaviour with unpopulated TLBMarcelo Tosatti1-2/+12
The proposed _tlbie call at update_mmu_cache() is safe because: Addresses for which update_mmu_cache() gets invocated are never inside the static kernel virtual mapping, meaning that there is no risk for the _tlbie() here to be thrashing the pinned entry, as Dan suspected. The intermediate TLB state in which this bug can be triggered is not visible by userspace or any other contexts, except the page fault handling path. So there is no need to worry about userspace dcbxxx users. The other solution to this is to avoid dcbst misbehaviour in the first place, which involves changing in-kernel "dcbst" callers to use 8xx specific SPR's. Summary: On 8xx, cache control instructions (particularly "dcbst" from flush_dcache_icache) fault as write operation if there is an unpopulated TLB entry for the address in question. To workaround that, we invalidate the TLB here, thus avoiding dcbst misbehaviour.

2005-06-27[PATCH] CFQ io scheduler: scheduler switch oopsJens Axboe1-2/+3
If cfq is managing a queue and a new scheduler is later selected, it is possible for the cfqd unplug_work work to be queued after the kblockd work struct has been flushed. The problem is the ordering of cfq_shutdown_timer_wq() and blk_put_queue() in cfq_put_cfqd(). The latter may rearm the work, leaving cfq_kick_queue() with dead data.

2005-06-27[PATCH] CFQ io scheduler updatesJens Axboe2-161/+300
- Adjust slice values - Instead of one async queue, one is defined per priority level. This prevents kernel threads (such as reiserfs/x and others) that run at higher io priority from conflicting with others. Previously, it was a coin toss what io prio the async queue got, it was defined by who first set up the queue. - Let a time slice only begin, when the previous slice is completely done. Previously we could be somewhat unfair to a new sync slice, if the previous slice was async and had several ios queued. This might need a little tweaking if throughput suffers a little due to this, allowing perhaps an overlap of a single request or so. - Optimize the calling of kblockd_schedule_work() by doing it only when it is strictly necessary (no requests in driver and work left to do). - Correct sync vs async logic. A 'normal' process can be purely async as well, and a flusher can be purely sync as well. Sync or async is now a property of the class defined and requests pending. Previously writers could be considered sync, when they were really async. - Get rid of the bit fields in cfqq and crq, use flags instead. - Various other cleanups and fixes Signed-off-by: Jens Axboe <axboe@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-06-27[PATCH] Fix cfq_find_next_crq()Jens Axboe1-1/+2
In cfq_find_next_crq(), cfq tries to find the next request by choosing one of two requests before and after the current one. Currently, when choosing the next request, if there's no next request, the next candidate is NULL, resulting in selection of the previous request. This results in weird scheduling. Once we reach the end, we always seek backward. The correct behavior is using the first request as the next candidate. cfq_choose_req() already has logics for handling wrapped requests.

2005-06-27[PATCH] Update cfq io scheduler to time sliced designJens Axboe26-690/+1683
This updates the CFQ io scheduler to the new time sliced design (cfq v3). It provides full process fairness, while giving excellent aggregate system throughput even for many competing processes. It supports io priorities, either inherited from the cpu nice value or set directly with the ioprio_get/set syscalls. The latter closely mimic set/getpriority.
