* RDMA/nes: Fix interrupt moderation low thresholdJohn Lacombe2008-02-26
| | | | | | | | | | | | | Interrupt moderation low threshold value was incorrectly triggering, indicating that the threshold should be lowered. The impact was the timer was likely to become 40usecs and get stuck there. The biggest side effect was too many interrupts and nonoptimal performance.

* RDMA/nes: Fix CRC endianness for RDMA connection establishment on big-endianFaisal Latif2008-02-26
| | | | | | | | | | | | | | With commit ef19454b ("[LIB] crc32c: Keep intermediate crc state in cpu order"), the behavior of crc32c changes on big-endian platforms. Our algorithm expects the previous behavior; otherwise we have RDMA connection establishment failure on big-endian platforms like powerpc. Apply cpu_to_le32() to value returned by crc32c() to get the previous behavior.

* RDMA/nes: Resurrect error path dead codeChien Tung2008-02-25
| | | | | | | | | | | | | | | | | Adrian Bunk pointed out that a Coverity scan found some apparently dead code in nes_verbs.c that really shouldn't have been dead. The function nes_create_cq() was missing the assignment err = 1; just prior to an iteration that conditionally set err = 0 if a PBL was found for a given virtual CQ. I also noticed we should have been returning -EFAULT on a couple related error paths.

* RDMA/cxgb3: Fix shift calc in build_phys_page_list() for 1-entry page listsBryan Rosenburg2008-02-25
| | | | | | | | | | | | | A single entry (addr 0x10001000, size 0x2000) will get converted to page address 0x10000000 with a page size of 0x4000. The code as it stands doesn't address the single buffer case, but in fact it allows the subsequent single-buffer special case to be eliminated entirely. Because the mask now includes the (page adjusted) starting and ending addresses, the general case works for the single buffer case as well.

This behavior has been confirmed by Marvell with a SATA analyzer. The Marvell port-multiplier apparently likes to see clean HOB information when accessing PMP registers. Since sata_mv uses PIO shadow register access, this doesn't happen automatically, as it might in a more purely FIS-based driver (eg. ahci). One way to fix this is to flag these commands with ATA_TFLAG_LBA48, forcing libata to write out the HOB fields with known (zero) values.

| * libata: automatically use DMADIR if drive/bridge requires itTejun Heo2008-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Back in 2.6.17-rc2, a libata module parameter was added for atapi_dmadir. That's nice, but most SATA devices which need it will tell us about it in their IDENTIFY PACKET response, as bit-15 of word-62 of the returned data (as per ATA7, ATA8 specifications). So for those which specify it, we should automatically use the DMADIR bit. Otherwise, disc writing will fail by default on many SATA-ATAPI drives. This patch adds ATA_DFLAG_DMADIR and make ata_dev_configure() set it if atapi_dmadir is set or identify data indicates DMADIR is necessary. atapi_xlat() is converted to check ATA_DFLAG_DMADIR before setting DMADIR.

* | NBD: make nbd default to deadline I/O schedulerPaul Clements2008-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NBD doesn't work well with CFQ (or AS) schedulers, so let's default to something else. The two problems I have experienced with nbd and cfq are: 1) nbd hangs with cfq on RHEL 5 (2.6.18) -- this may well have been fixed There's a similar debian bug that has been filed as well: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=447638 There have been posts to nbd-general mailing list about problems with cfq and nbd also. 2) nbd performs about 10% better (the last time I tested) with deadline vs. cfq (the overhead of cfq doesn't provide much advantage to nbd [not being a real disk], and you end up going through the I/O scheduler on the nbd server anyway, so it makes sense that deadline is better with nbd) Signed-off-by: Paul Clements <paul.clements@steeleye.com> Cc: Jens Axboe <jens.axboe@oracle.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* | dmi: don't save the same device twiceJean Delvare2008-02-23
| | | | | | | | | | | | | | | | | | | | | | | | Now that we gather on-board devices from both DMI types 10 and 41, there is a possibility that we list the same device twice. In order to not confuse drivers, and also to save memory, make sure that we do not add duplicate devices to the dmi_devices list.

* | rtc-cmos: display HPET emulation modeDavid Brownell2008-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the "cmos" RTC, have /proc/driver/rtc say whether HPET based IRQ emulation is in effect. Given the problems we've had with this particular hardware maldesign (and the fact that most BIOS code seems not to provide the IRQ routing needed to use the saner HPET modes), this should help troubleshooting.

* | spi: pxa2xx_spi clock polarity fixNed Forrester2008-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes a sequencing bug in spi driver pxa2xx_spi.c in which the chip select for a transfer may be asserted before the clock polarity is set on the interface. As a result of this bug, the clock signal may have the wrong polarity at transfer start, so it may need to make an extra half transition before the intended clock/data signals begin. (This probably means all transfers are one bit out of sequence.) This only occurs on the first transfer following a change in clock polarity in systems using more than one more than one such polarity. The fix assures that the clock mode is properly set before asserting chip select. This bug was introduced in a patch merged on 2006/12/10, kernel 2.6.20. The patch defines an additional bit in: include/asm-arm/arch-pxa/regs-ssp.h for 2.6.25 and newer kernels but this addition must be made in: include/asm-arm/arch-pxa/pxa-regs.h for kernels between 2.6.20 and 2.6.24, inclusive Signed-off-by: Ned Forrester <nforrester@whoi.edu> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Cc: Russell King <rmk@arm.linux.org.uk> Cc: <stable@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
