2014-05-15IB/qib: add missing braces in do_qib_user_sdma_queue_create()Yann Droneaud1-1/+2
commit 37a967651caf99dd267017023737bd442f5acb3d upstream. Commit c804f07248895ff9c moved qib_assign_ctxt() to do_qib_user_sdma_queue_create() but dropped the braces around the statements.

2013-08-13IB/qib: Improve SDMA performanceCQ Tang1-1/+1
1. The code accepts chunks of messages, and splits the chunk into packets when converting packets into sdma queue entries. Adjacent packets will use user buffer pages smartly to avoid pinning the same page multiple times. 2. Instead of discarding all the work when SDMA queue is full, the work is saved in a pending queue. Whenever there are enough SDMA queue free entries, pending queue is directly put onto SDMA queue. 3. An interrupt handler is used to progress this pending queue.

2013-06-22IB/qib: Add dual-rail NUMA awareness for PSM processesRamkrishna Vepa1-49/+125
The driver currently selects a HCA based on the algorithm that PSM chooses, contexts within a HCA or across. The HCA can also be chosen by the user. Either way, this patch assigns a CPU on the NUMA node local to the selected HCA. This patch also tries to select the HCA closest to the NUMA node of the CPU assigned via taskset to PSM process. If this HCA is unusable then another unit is selected based on the algorithm that is currently enforced or selected by PSM - round robin context selection 'within' or 'across' HCA's. Fixed a bug wherein contexts are setup on the NUMA node on which the processes are opened (setup_ctxt()) and not on the NUMA node that the driver recommends the CPU on.

2013-06-22IB/qib: Add optional NUMA affinityRamkrishna Vepa1-1/+5
This patch adds context relative numa affinity conditioned on the module parameter numa_aware. The qib_ctxtdata has an additional node_id member and qib_create_ctxtdata() has an addition node_id parameter. The allocations within the hdr queue and eager queue setup routines now take this additional member and adjust allocations as necesary. PSM will pass the either current numa node or the node closest to the HCA depending on numa_aware. Verbs will always use the node closest to the HCA.

2012-10-09mm: kill vma flag VM_RESERVED and mm->reserved_vm counterKonstantin Khlebnikov1-1/+1
A long time ago, in v2.4, VM_RESERVED kept swapout process off VMA, currently it lost original meaning but still has some effects: | effect | alternative flags -+------------------------+--------------------------------------------- 1| account as reserved_vm | VM_IO 2| skip in core dump | VM_IO, VM_DONTDUMP 3| do not merge or expand | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP 4| do not mlock | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP This patch removes reserved_vm counter from mm_struct. Seems like nobody cares about it, it does not exported into userspace directly, it only reduces total_vm showed in proc. Thus VM_RESERVED can be replaced with VM_IO or pair VM_DONTEXPAND | VM_DONTDUMP. remap_pfn_range() and io_remap_pfn_range() set VM_IO|VM_DONTEXPAND|VM_DONTDUMP. remap_vmalloc_range() set VM_DONTEXPAND | VM_DONTDUMP.

2011-10-06IB/qib: Correct nfreectxts for multiple HCAsMike Marciniszyn1-0/+2

2011-07-18IB/qib: Fix potential deadlock with link down interruptRam Vepa1-2/+3
There is a possibility of a deadlock due to the way locks are acquired and released in qib_set_uevent_bits(). The function qib_set_uevent_bits() is called in process context and it uses spin_lock() and spin_unlock(). This same lock is acquired/released in interrupt context which can lead to a deadlock when running on the same cpu. The fix is to replace spin_lock() and spin_unlock() with spin_lock_irqsave() and spin_unlock_irqrestore() respectively in qib_set_uevent_bits().

2010-10-15llseek: automatically add .llseek fopArnd Bergmann1-1/+2
All file_operations should get a .llseek operation so we can make nonseekable_open the default for future file operations without a .llseek pointer. The three cases that we can automatically detect are no_llseek, seq_lseek and default_llseek. For cases where we can we can automatically prove that the file offset is always ignored, we use noop_llseek, which maintains the current behavior of not returning an error from a seek. New drivers should normally not use noop_llseek but instead use no_llseek and call nonseekable_open at open time. Existing drivers can be converted to do the same when the maintainer knows for certain that no user code relies on calling seek on the device file. The generated code is often incorrectly indented and right now contains comments that clarify for each added line why a specific variant was chosen. In the version that gets submitted upstream, the comments will be gone and I will manually fix the indentation, because there does not seem to be a way to do that using coccinelle. Some amount of new code is currently sitting in linux-next that should get the same modifications, which I will do at the end of the merge window. Many thanks to Julia Lawall for helping me learn to write a semantic patch that does all this. ===== begin semantic patch ===== // This adds an llseek= method to all file operations, // as a preparation for making no_llseek the default. // // The rules are // - use no_llseek explicitly if we do nonseekable_open // - use seq_lseek for sequential files // - use default_llseek if we know we access f_pos // - use noop_llseek if we know we don't access f_pos, // but we still want to allow users to call lseek // @ open1 exists @ identifier nested_open; @@ nested_open(...) { <+... nonseekable_open(...) ...+> } @ open exists@ identifier open_f; identifier i, f; identifier open1.nested_open; @@ int open_f(struct inode *i, struct file *f) { <+...
