2007-05-16ide: remove ide_use_dma()Bartlomiej Zolnierkiewicz
ide_use_dma() duplicates a lot of ide_max_dma_mode() functionality and as all users of ide_use_dma() were converted to use ide_tune_dma() now it is possible to add missing checks to ide_tune_dma() and remove ide_use_dma() completely, so do it. There should be no functionality changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2007-05-16sl82c105: add speedproc() method and MWDMA0/1 supportSergei Shtylyov
Add the speedproc() method for setting transfer modes, modify config_for_dma() to call it and use ide_max_dma_mode() to select the best DMA mode. Add support for the multiword DMA modes 0 and 1, using the upper half of the 'drive_data' field to store the DMA timings to program into the drive control register when DMA is turned on for real.

CS5530/SC1200 specifies that two drives on the same cable cannot mix UDMA/MDMA. Add {cs5530,sc1200}_udma_filter() to handle this. This also makes it possible to remove open-coded best DMA mode selection and use standard ide_use_dma()/ide_max_dma_mode() helpers. While at it bump version numbers.

* limit max PIO mode to PIO4, this driver doesn't support PIO5 and attempt to program PIO5 by config_art_rwp_pio() could result in incorrect PIO timings being programmed and possibly the data corruption (for < ATA100 family chipsets PIO0 timings were used, for ATA100 and ATA100a - the random content of test1 variable was used, for ATA133 - MWDMA0 timings were used) * BUG() in sis5513_tune_chipset() if somebody tries to force unsupported PIO5, also cleanup this function a bit while at it * add comment about PIO0 timings for < ATA100 family chipsets * remove open-coded best PIO mode selection from config_art_rwp_pio(), it contained numerous bugs: - it didn't check for validity of id->eide_pio_modes and id->eide_pio_iordy before using them - it tried to found out maximum PIO mode basing on minimum IORDY cycle time (moreover wrong cycle times were used for PIO1/5) - it was overriding PIO blacklist and conservative PIO "downgrade" done by ide_get_best_pio_mode() * use sis5513_tune_drive() instead of config_art_rwp_pio() in sis5513_config_xfer_rate() so the correct PIO mode is also set on drive even if the device is not IORDY/DMA capable * config_art_rwp_pio() was always setting the best possible mode and not the wanted one - fix it and move ide_get_best_pio_mode() call to config_chipset_for_pio() * don't use ide_find_best_mode() in config_chipset_for_pio(), it was being overriden by config_art_rwp_pio() for the host timings anyway + we need to set the same PIO mode on the device and the host * pass correct "pio" argument (255 instead of 5) to sis5513_tune_drive() call in sis5513_config_xfer_rate() so the best PIO mode is set on the drive and not PIO4 * rename sis5513_tune_drive() to sis5513_tuneproc() and config_chipset_for_pio() to sis5513_tune_driver() * bump driver version Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2007-05-16pdc202xx_old: rewrite mode programming code (v2)Bartlomiej Zolnierkiewicz
This patch is based on the documentation (I would like to thank Promise for it) and also partially on the older vendor driver. Rewrite mode programming code: * disable 66MHz clock in pdc202xx_tune_chipset() so it is correctly disabled even if both devices on the channel are not DMA capable and after reset * enable/disable IORDY and PREFETCH bits in pdc202xx_tune_chipset() as they need to be setup correctly also for PIO only devices, plus IORDY wasn't disabled for non-IORDY devices and PREFETCH wasn't disabled for ATAPI devices * remove dead code for setting SYNC_ERDDY_EN bits from config_chipset_for_dma() (driver sets ->autotune to 1 so PIO modes are always programmed => lower nibble of register A never equals 4 => "chipset_is_set" is always true) * enable PIO mode programming for all ATAPI devices (it was limited to ->media == ide_cdrom devices) * remove extra reads of registers A/B/C, don't read register D et all * do clearing / programming of registers A/B/C in one go (gets rid of extra PCI config space read/write cycle) * set initial values of drive_conf/AP/BP/CP variables to zero (paranoia for the case when PCI reads fail) * remove XFER_UDMA6 to XFER_UDMA5 remapping case - it can't happen (ide_rate_filter() takes care of it) * fix XFER_MW_DMA0 timings (they were overclocked, use the official ones) * fix bitmasks for clearing bits of register B: - when programming DMA mode bit 0x10 of register B was cleared which resulted in overclocked PIO timing setting (iff PIO0 was used) - when programming PIO mode bits 0x18 weren't cleared so suboptimal timings were used for PIO1-4 if PIO0 was previously set (bit 0x10) and for PIO0/3/4 if PIO1/2 was previously set (bit 0x08) * add FIXME comment about missing locking for 66MHz clock register Also while at it: * remove unused defines * do a few cosmetic / CodingStyle fixes * bump driver version v2: * in pdc202xx_tune_chipset() the old content of drive configuration registers is used only by the debugging code so cover "drive_conf" PCI registers read by #if PDC202XX_DEBUG_DRIVE_INFO (Noticed by Sergei Shtylyov) Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2007-05-15Remove cpu hotplug defines for __INIT & __INITDATAPrarit Bhargava
After examining what was checked in and the code base I discovered that most of 86c0baf123e474b6eb404798926ecf62b426bf3a wasn't necessary anymore.... So here's a patch that reverts the last part of that changeset: Revert part of 86c0baf123e474b6eb404798926ecf62b426bf3a.

2007-05-15fix epoll single pass code and add wait-exclusive flagDavide Libenzi
Fixes the epoll single pass code. During the unlocked event delivery (to userspace) code, the poll callback can re-issue new events, and we must receive them correctly. Since we loop in a lockless fashion, we want to be O(nready), and we don't want to flash on/off the spinlock for every event, we have the poll callback to use a secondary list to queue events while we're inside the event delivery loop. The rw_semaphore has been turned into a mutex. This patch also adds the wait-exclusive flag, as suggested by Davi Arnaut.

This reverts commit f64da958dfc83335de1d2bef9d3868f30feb4e53. Andi Kleen is unhappy with the changes, and they really do not seem worth it. IPMI could use DIE_NMI_IPI instead of the new callback, even though that ends up having its own set of problems too, mainly because the IPMI code cannot really know the NMI was from IPMI or not.

2007-05-14RDMA/cma: Add check to validate that cm_id is bound to a deviceSean Hefty
Several checks in the rdma_cm check against the state of the cm_id, but only to validate that the cm_id is bound to an underlying transport specific CM and an RDMA device. Make the check explicit in what we're trying to check for, since we're not synchronizing against the cm_id state.

Some pSeries hypervisor versions show a race condition in the allocate MR hCall. Serialize this call per adapter to circumvent this problem. Signed-off-by: Joachim Fenkes <fenkes@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2007-05-14IB/ipath: Shadow the gpio_mask registerArthur Jones
Once upon a time, GPIO interrupts were rare. But then a chip bug in the waldo series forced the use of a GPIO interrupt to signal packet reception. This greatly increased the frequency of GPIO interrupts which have the gpio_mask bits set on the waldo chips. Other bits in the gpio_status register are used for I2C clock and data lines, these bits are usually on. An "unlikely" annotation leftover from the old days was improperly applied to these bits, and an unnecessary chip mmio read was being accessed in the interrupt fast path on waldo. Remove the stagnant unlikely annotation in the interrupt handler and keep a shadow copy of the gpio_mask register to avoid the slow mmio read when testing for interruptable GPIO bits.

2007-05-14IB/mlx4: Fix uninitialized spinlock for 32-bit archsJack Morgenstein
uar_lock spinlock was used in mlx4_ib_cq_arm without being initialized (this only affects 32-bit archs, because uar_lock is not used on 64-bit archs and MLX4_INIT_DOORBELL_LOCK() is a NOP). Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
