2007-06-18IB/mlx4: Handle FW command interface rev 3Roland Dreier
Upcoming firmware introduces command interface revision 3, which changes the way port capabilities are queried and set. Update the driver to handle both the new and old command interfaces by adding a new MLX4_FLAG_OLD_PORT_CMDS that it is set after querying the firmware interface revision and then using the correct interface based on the setting of the flag.

2007-06-18IB/mlx4: Handle buffer wraparound in __mlx4_ib_cq_clean()Jack Morgenstein
When compacting CQ entries, we need to set the correct value of the ownership bit in case the value is different between the index we copy the CQE from and the index we copy it to. Found by Ronni Zimmerman of Mellanox. Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2007-06-18IB/mlx4: Get rid of max_inline_data calculationRoland Dreier
The calculation of max_inline_data in set_kernel_sq_size() is bogus, since it doesn't take into account the fact that inline segments may not cross a 64-byte boundary, and hence multiple inline segments will probably need to be used to post large inline sends. We don't support inline sends for kernel QPs anyway, so there's no point in doing this calculation anyway, since the field is just zeroed out a little later. So just delete the bogus calculation. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2007-06-18IB/mlx4: Handle new FW requirement for send request prefetchingRoland Dreier
New ConnectX firmware introduces FW command interface revision 2, which requires that for each QP, a chunk of send queue entries (the "headroom") is kept marked as invalid, so that the HCA doesn't get confused if it prefetches entries that haven't been posted yet. Add code to the driver to do this, and also update the user ABI so that userspace can request that the prefetcher be turned off for userspace QPs (we just leave the prefetcher on for all kernel QPs). Unfortunately, marking send queue entries this way is confuses older firmware, so we change the driver to allow only FW command interface revisions 2. This means that users will have to update their firmware to work with the new driver, but the firmware is changing quickly and the old firmware has lots of other bugs anyway, so this shouldn't be too big a deal. Based on a patch from Jack Morgenstein <jackm@dev.mellanox.co.il>. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2007-06-12IB/mlx4: Fix warning in rounding up queue sizesRoland Dreier
Doing max(1, foo) where foo is u32 generates a warning, because 1 is a signed constant. Fix this by using 1U instead. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2007-06-12IB/mlx4: Fix handling of wq->tail for send completionsRoland Dreier
Cast the increment added to wq->tail when send completions are processed to u16 to avoid using wrong values caused by standard integer promotions. The same bug was fixed in libmlx4 by Eli Cohen <eli@mellanox.co.il>. Signed-off-by: Roland Dreier <rolandd@cisco.com>

2007-06-11[MIPS] Fix KMODE for the R3000Maciej W. Rozycki
This must be the oldest bug that we have got. Leaving interrupts "as they are" for the R3000 obviously means copying IEp to IEc. Since we have got STATMASK now, I took this opportunity to mask the status register "correctly" for the R3000 now too. Oh, and the R3000 hardly ever is 64-bit. Signed-off-by: Maciej W.

2007-06-11libata: limit post SRST nsect/lbal wait to ~100msTejun Heo
After SRST, libata used to wait for nsect/lbal to be set to 1/1 for the slave device. However, some ATAPI devices don't set nsect/lbal after SRST and the wait itself isn't too useful as we're gonna wait for !BSY right after that anyway. Before reset-seq update, nsect/lbal wait failure used to be ignored and caused 30sec delay during detection. After reset-seq, all timeouts are considered error conditions making libata fail to detect such ATAPI devices. This patch limits nsect/lbal wait to around 100ms. This should give acceptable behavior to such ATAPI devices while not disturbing the heavily used code path too much.

2007-06-09libata-core/sff: Fix multiple assumptions about DMAAlan Cox
The ata IRQ ack functions are only used when debugging. Unfortunately almost every controller that calls them can cause crashes in some configurations as there are missing checks for bmdma presence. In addition ata_port_start insists of installing DMA buffers and pad buffers for controllers regardless. The SFF controllers actually need to make that decision dynamically at controller setup time and all need the same helper - so we add ata_sff_port_start. Future patches will switch the SFF drivers to use this. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2007-06-08hexdump: more output formattingRandy Dunlap
Add a prefix string parameter. Callers are responsible for any string length/alignment that they want to see in the output. I.e., callers should pad strings to achieve alignment if they want that. Add rowsize parameter. This is the number of raw data bytes to be printed per line. Must be 16 or 32. Add a groupsize parameter. This allows callers to dump values as 1-byte, 2-byte, 4-byte, or 8-byte numbers. Default is 1-byte numbers. If the total length is not an even multiple of groupsize, 1-byte numbers are printed. Add an "ascii" output parameter. This causes ASCII data output following the hex data output. Clean up some doc examples. Align the ASCII output on all lines that are produced by one call. Add a new interface, print_hex_dump_bytes(), that is a shortcut to print_hex_dump(), using default parameter values to print 16 bytes in byte-size chunks of hex + ASCII output, using printk level KERN_DEBUG.
