2006-06-10[PATCH] Further alterations for memory barrier documentDavid Howells1-78/+270
From: David Howells <dhowells@redhat.com> Apply some alterations to the memory barrier document that I worked out with Paul McKenney of IBM, plus some of the alterations suggested by Alan Stern. The following changes were made: (*) One of the examples given for what can happen with overlapping memory barriers was wrong. (*) The description of general memory barriers said that a general barrier is a combination of a read barrier and a write barrier. This isn't entirely true: it implies both, but is more than a combination of both. (*) The first example in the "SMP Barrier Pairing" section was wrong: the loads around the read barrier need to touch the memory locations in the opposite order to the stores around the write barrier. (*) Added a note to make explicit that the loads should be in reverse order to the stores. (*) Adjusted the diagrams in the "Examples Of Memory Barrier Sequences" section to make them clearer. Added a couple of diagrams to make it more clear as to how it could go wrong without the barrier. (*) Added a section on memory speculation. (*) Dropped any references to memory allocation routines doing memory barriers. They may do sometimes, but it can't be relied on. This may be worthy of further documentation later. (*) Made the fact that a LOCK followed by an UNLOCK should not be considered a full memory barrier more explicit and gave an example.

Grand unification of the three types of workarounds we have so far. The "skip mode page 8" workaround is now limited to devices which pretend to be of TYPE_DISK instead of TYPE_RBC. This workaround is no longer enabled for Initio bridges. Patch update in anticipation of more workarounds: - Add module parameter "workarounds". - Deprecate parameter "force_inquiry_hack". - Compose the blacklist of a compound type for better readability and extensibility. - Remove a now unused #define.

2006-04-27[SCSI] megaraid_{mm,mbox}: fix a bug in reset handlerJu, Seokmann1-0/+25
When abort failed, the driver gets reset handleer called. In the reset handler, driver calls 'scsi_done()' callback for same SCSI command packet (struct scsi_cmnd) multiple times if there are multiple SCSI command packet in the pend_list. More over, if there are entry in the pend_lsit with IOCTL packet associated, the driver returns it to wrong free_list so that, in turn, the driver could end up with 'NULL pointer dereference..' during I/O command building with incorrect resource. Also, the patch contains several minor/cosmetic changes besides this.

2006-04-14[PATCH] dma doc updatesDavid Brownell2-18/+53
This updates the DMA API documentation to address a few issues: - The dma_map_sg() call results are used like pci_map_sg() results: using sg_dma_address() and sg_dma_len(). That's not wholly obvious to folk reading _only_ the "new" DMA-API.txt writeup. - Buffers allocated by dma_alloc_coherent() may not be completely free of coherency concerns ... some CPUs also have write buffers that may need to be flushed. - Cacheline coherence issues are now mentioned as being among issues which affect dma buffers, and complicate/prevent using of static and (especially) stack based buffers with the DMA calls. I don't think many drivers currently need to worry about flushing write buffers, but I did hit it with one SOC using external SDRAM for DMA descriptors: without explicit writebuffer flushing, the on-chip DMA controller accessed descriptors before the CPU completed the writes.

Also explains why special barriers exist in addition to normal barriers. Further fix the memory barrier documents to portray bitwise operation memory barrier effects correctly following Nick Piggin's comments. It makes the point that any atomic op that both modifies some state in memory and returns information on that state implies memory barriers on both sides.

2006-04-10[PATCH] move ->eh_strategy_handler to the transport classChristoph Hellwig3-27/+8
Overriding the whole EH code is a per-transport, not per-host thing. Move ->eh_strategy_handler to the transport class, same as ->eh_timed_out. Downside is that scsi_host_alloc can't check for the total lack of EH anymore, but the transition period from old EH where we needed it is long gone already.

2006-04-09[PATCH] x86_64: Reserve SRAT hotadd memory on x86-64Andi Kleen1-0/+5
From: Keith Mannthey, Andi Kleen Implement memory hotadd without sparsemem. The memory in the SRAT hotadd area is just preserved instead and can be activated later. There are a few restrictions: - Only one continuous hotadd area allowed per node The main problem is dealing with the many buggy SRAT tables that are out there. The strategy here is to reject anything suspicious. Originally from Keith Mannthey, with several hacks and changes by AK and also contributions from Andrew Morton [ TBD: Problems pointed out by KAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com>: 1) Goto's rebuild_zonelist patch will not work if CONFIG_MEMORY_HOTPLUG=n. Rebuilding zonelist is necessary when the system has just memory < 4G at boot, and hot add memory > 4G. because x86_64 has DMA32, ZONE_NORAML is not included into zonelist at boot time if system doesn't have memory >4G at boot. [AK: should just force the higher zones at boot time when SRAT tells us] 2) zone and node's spanned_pages and present_pages are not incremented. They should be. For example, our server (ia64/Fujitsu PrimeQuest) can equip memory from 4G to 1T(maybe 2T in future), and SRAT will *always* say we have possible 1T +memory. (Microsoft requires "write all possible memory in SRAT") When we reserve memmap for possible 1T memory, Linux will not work well in +minimum 4G configuraion ;) [AK: needs limiting to 5-10% of max memory] ] Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
