IB/ipath: Remove support for QLogic PCIe QLE devices

2010-05-24T05:14:25Z

The ib_qib driver is taking over support for QLogic PCIe QLE devices, so remove support for them from ib_ipath. The ib_ipath driver now supports only the obsolete QLogic Hyper-Transport IB host channel adapter (model QHT7140). Signed-off-by: Ralph Campbell Signed-off-by: Roland Dreier

driver model: constify attribute groups

2009-09-15T16:50:47Z

Let attribute group vectors be declared "const". We'd like to let most attribute metadata live in read-only sections... this is a start. Signed-off-by: David Brownell Signed-off-by: Greg Kroah-Hartman

IB/ipath: Add locking for interrupt use of ipath_pd contexts vs free

2008-12-05T19:14:38Z

Fixes timing race resulting in panic. Not a performance sensitive path. Signed-off-by: Dave Olson Signed-off-by: Roland Dreier

IB/ipath: Don't count IB symbol and link errors unless link is UP

2008-12-05T19:13:19Z

Implement the ignoring of ibsymbol errors and linkrecover errors while the link is at less than INIT (long needed), to get accurate counts. Particularly an issue when doing non-IBTA DDR negotiation with chips from vendors that do not support IBTA mode negotiation. If the driver is unloaded, and there is a delta, the adjusted counters are written back to the chip, so they stay adjusted across driver reload.

IB/ipath: Avoid test_bit() on u64 SDMA status value

2008-05-26T22:20:34Z

Gabriel C pointed out that when the x86 bitops are updated to operate on unsigned long, the code in sdma_abort_task() will produce warnings: drivers/infiniband/hw/ipath/ipath_sdma.c: In function 'sdma_abort_task': drivers/infiniband/hw/ipath/ipath_sdma.c:267: warning: passing argument 2 of 'constant_test_bit' from incompatible pointer type and so on, because it uses test_bit() to operation on a u64 value (returned by ipath_read_kref64() for a hardware register). Fix up these warnings by converting the test_bit() operations to &ing with appropriate symbolic defines of the bits within the hardware register. This has the benign side-effect of making the code more self-documenting as well. Signed-off-by: Roland Dreier

IB/ipath: Change ipath_devdata.ipath_sdma_status to be unsigned long

2008-05-13T18:51:23Z

Andrew Morton pointed out that bitops should take an unsigned long * arg. However, the ipath driver was doing bitops on struct ipath_devdata.ipath_sdma_status, which is u64. Change this member to unsigned long to avoid tons of warnings when x86 fixes the bitops to take unsigned long * instead of void *. Also, change the IPATH_SDMA_RUNNING and IPATH_SDMA_SHUTDOWN bit numbers to 30 and 31 (instead of 62 and 63) so that we're not setting another booby trap for someone who tries to make ipath work on a 32-bit architecture.

IB/ipath: Make ipath_portdata work with struct pid * not pid_t

2008-05-13T18:45:32Z

The official reason is "with the presence of pid namespaces in the kernel using pid_t-s inside one is no longer safe." But the reason I fix this right now is the following: About a month ago (when 2.6.25 was not yet released) there still was a one last caller of a to-be-deprecated-soon function find_pid() - the kill_proc() function, which in turn was only used by nfs callback code. During the last merge window, this last caller was finally eliminated by some NFS patch(es) and I was about to finally kill this kill_proc() and find_pid(), but found, that I was late and the kill_proc is now called from the ipath driver since commit 58411d1c ("IB/ipath: Head of Line blocking vs forward progress of user apps"). So here's a patch that fixes this code to use struct pid * and (!) the kill_pid routine. Signed-off-by: Pavel Emelyanov Signed-off-by: Roland Dreier

IB/ipath: Need to always request and handle PIO avail interrupts

2008-05-07T18:00:15Z

Now that we always use PIO for vl15 on 7220, we could get stuck forever if we happened to run out of PIO buffers from the verbs code, because the setup code wouldn't run; the interrupt was also ignored if SDMA was supported. We also have to reduce the pio update threshold if we have fewer kernel buffers than the existing threshold. Clean up the initialization a bit to get ordering safer and more sensible, and use the existing ipath_chg_kernavail call to do init, rather than doing it separately. Drop unnecessary clearing of pio buffer on pio parity error. Drop incorrect updating of pioavailshadow when exitting freeze mode (software state may not match chip state if buffer has been allocated and not yet written). If we couldn't get a kernel buffer for a while, make sure we are in sync with hardware, mainly to handle the exitting freeze case. Signed-off-by: Dave Olson Signed-off-by: Roland Dreier

IB: convert struct class_device to struct device

This converts the main ib_device to use struct device instead of struct class_device as class_device is going away. Signed-off-by: Tony Jones Signed-off-by: Kay Sievers Cc: Roland Dreier Cc: Sean Hefty Cc: Hal Rosenstock Signed-off-by: Greg Kroah-Hartman
