2009-03-26ext3: Avoid starting a transaction in writepage when not necessaryJan Kara
We don't have to start a transaction in writepage() when all the blocks are a properly allocated. Even in ordered mode either the data has been written via write() and they are thus already added to transaction's list or the data was written via mmap and then it's random in which transaction they get written anyway. This should help VM to pageout dirty memory without blocking on transaction commits. Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2009-03-26writeback: double the dirty thresholdsWu Fengguang
Enlarge default dirty ratios from 5/10 to 10/20. This fixes [Bug #12809] iozone regression with 2.6.29-rc6. The iozone benchmarks are performed on a 1200M file, with 8GB ram. iozone -i 0 -i 1 -i 2 -i 3 -i 4 -r 4k -s 64k -s 512m -s 1200m -b tmp.xls iozone -B -r 4k -s 64k -s 512m -s 1200m -b tmp.xls The performance regression is triggered by commit 1cf6e7d83bf3(mm: task dirty accounting fix), which makes more correct/thorough dirty accounting. The default 5/10 dirty ratios were picked (a) with the old dirty logic and (b) largely at random and (c) designed to be aggressive. In particular, that (a) means that having fixed some of the dirty accounting, maybe the real bug is now that it was always too aggressive, just hidden by an accounting issue. The enlarged 10/20 dirty ratios are just about enough to fix the regression.

2009-03-24RDMA/cxgb3: Enforce required firmwareSteve Wise
The cxgb3 NIC driver can handle more firmware versions than iw_cxgb3, and since commit 8207befa ("cxgb3: untie strict FW matching") cxgb3 will load with firmware versions that iw_cxgb3 can't handle. The FW major number indicates a specific interface between the FW and iw_cxgb3. Thus if the major number of the running firmware does not match the required version compiled into iw_cxgb3, then iw_cxgb3 must not register that device.

2009-03-24[libata] More robust parsing for IDENTIFY DEVICE multi_count fieldMark Lord
Make libata more robust when parsing the multi_count field from a drive's identify data. This prevents us from attempting to use dubious multi_count values ad infinitum. Reset dev->multi_count to zero and reprobe it each time through this routine, as it can change on device reset. Also ensure that the reported "maximum" value is valid and is a power of two, and that the reported "count" value is valid and also a power of two. And that the "count" value is not greater than the "maximum" value. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2009-03-24sata_mv: fix LED blinking for SoC+NCQMark Lord

Normal LED function is restored when NCQ is not enabled on any port. The code to enable the blink mode is based on earlier code and suggestions from Frans Pop, Saeed Bishara, and possibly others.

Enable use of the "all ports" IRQ coalescing optimization for GEN_II / GEN_IIE chips that have dual host-controllers (8-ports). Currently only the 6081 chip qualifies, but other chips may come along someday. Rather than each half of the chip having to satisfy a local set of coalescing thresholds, use of this feature groups all ports together under a single set of thresholds.

2009-03-24sata_mv: implement IRQ coalescing (v2)Mark Lord
Add IRQ coalescing to sata_mv (off by default). This feature can reduce total interrupt overhead for RAID setups in some situations, by deferring the interrupt signal until one or both of: a) a specified io_count (completed SATA commands) is achieved, or b) a specified time interval elapses after an IO completion. For now, module parameters are used to set the irq_coalescing_io_count and irq_coalescing_usecs (timeout) globally. These may eventually be supplemented with sysfs attributes, so that thresholds can be set on-the-fly and on a per-chip (or even per-host_controller) basis.

2009-03-24[libata] sata_mv: Add a new mv_sff_check_status() function to sata_mv.Mark Lord
This is necessary for use with the upcoming "mv_qc_issue_fis()" patch, but is being added separately here for easier code review. When using command issue via the "mv_qc_issue_fis()" mechanism, the initial ATA_BUSY bit does not show in the ATA status (shadow) register. This can confuse libata! So here we add a hook to fake ATA_BUSY for that situation, until the first time a BUSY, DRQ, or ERR bit is seen.

2009-03-24[libata] sata_mv: Tighten up interrupt masking in mv_qc_issue()Mark Lord
so that it doesn't miss any protocols. Handle future cases where a qc is specially marked for polled issue or where a particular chip version prefers interrupts over polling for PIO. This mimics the polling decision logic from ata_sff_qc_issue(). Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2009-03-24[libata] sata_mv: Enable use of (basic) DMA for ATAPI on GEN_IIE chipsMark Lord
This also gets rid of any need for mv_mode_filter(). Using basic DMA on GEN_IIE requires setting an undocumented bit in an undocumented register. For safety, we clear that bit again when switching back to EDMA mode. To avoid a performance penalty when switching modes, we cache the register in port_priv, as already done for other regs.

2009-03-24[libata] sata_mv: cache frequently-accessed registersMark Lord
Maintain a local (mv_port_priv) cache of frequently accessed registers, to avoid having to re-read them (very slow) on every transistion between EDMA and non-EDMA modes. This speeds up things like flushing the drive write cache, and anything using basic DMA transfers. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2009-03-24ahci: drop intx manipulation on msi enableTejun Heo
There's no need to turn off intx explicitly on msi enable. This is automatically handled by pci. Drop it. This might be needed on machines if the BIOS turns intx off during boot. However, there's no evidence of such behavior for ahci and the only such case seems to be ICH5 PATA according to ata_piix. Also, given the way ahci operates, it's highly unlikely BIOS ever disables IRQ for the controller. However, as this change has slight possibility of introducing failure, please schedule it for #upstream. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2009-03-24pata-rb532-cf: drop custom freeze and thawPhil Sutter
I'm not quite sure what freezing and thawing is used for. Tests showed that the port is being frozen at initialisation state and thawed right afterwards, then the functions were not called anymore. Dropping the complete custom code for handling the frozen state seems to work at least for a standard use case including mounting a partition, copying some files in it (in parallel) and finally removing them and unmounting the partition.

2009-03-24pata-rb532-cf: use ata_sff_data_xfer32()Phil Sutter
The biggest difference between rb532_pata_data_xfer() and ata_sff_data_xfer32() is the call to ata_sff_pause() at the end of rb532_pata_data_xfer() which I suppose to be unnecessary since it works without. I've also tested using ata_sff_data_xfer() as replacement, but since we know that the driver supports 32bit IO, using the optimised version should be safe.

2009-03-24pata-rb532-cf: use ata_sff_exec_command()Phil Sutter
The only difference between rb532_pata_exec_command() and ata_sff_exec_command() is added debugging output, so it can be dropped and the standard op used instead. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2009-03-24pata-rb532-cf: replace rb532_pata_finish_io()Phil Sutter
Since the delay used internally is just the same as ata_sff_pause() uses, rb532_pata_finish_io() does exactly the same as ata_sff_pause() and thus can be replaced by the later one. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
