* IB/mthca: Don't execute QUERY_QP firmware command for QP in RESET stateDotan Barak2007-01-09

* IB/ehca: Use proper GFP_ flags for get_zeroed_page()Hoang-Nam Nguyen2007-01-09
| | | | | | | | | | | | | | | | Here is a patch for ehca to use proper flag, ie. GFP_ATOMIC resp. GFP_KERNEL, when calling get_zeroed_page() to prevent "Bug: scheduling while atomic...". This error does not cause a kernel panic but makes ipoib un-usable afterwards. It is reproducible on 2.6.20-rc4 if one does ifconfig down during a flood ping test. I have not observed this error in earlier releases incl. 2.6.20-rc1. This error occurs when a qp event/irq is received and ehca event handler allocates a control block/page to obtain HCA error data block. Use of GFP_ATOMIC when in interrupt context prevents this issue. Signed-off-by Hoang-Nam Nguyen <hnguyen@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/mthca: Fix PRM compliance problem in atomic-send completionsJack Morgenstein2007-01-07
| | | | | | | | | | | | According to the Tavor and Arbel programmer's reference manuals, the number of bytes transferred is not provided in the byte_cnt field of the CQ entry for atomic operation completions. For atomic operations, the number of bytes transferred is always 8 (when the status is "success"), and this constant value should always be used by the driver in the ib_wc entry returned, rather than using the CQE.

* IB/mthca: Fix off-by-one in FMR handling on memfreeMichael S. Tsirkin2007-01-04
| | | | | | | | | | | | | | | | | | | mthca_table_find() will return the wrong address when the table entry being searched for is exactly at the beginning of a sglist entry (other than the first), because it uses >= when it should use >. Example: assume we have 2 entries in scatterlist, 4K each, offset is 4K. The current code will return first entry + 4K when we really want the second entry. In particular this means mapping an FMR on a memfree HCA may end up writing the page table into the wrong place, leading to memory corruption and also causing the HCA to use an incorrect address translation table.

| | | | | | | | | | | Commit 51f65ebc ("IB/ipath - program intconfig register using new HT irq hook"), which fixed interrupts for HyperTransport HCAs, broke PCI Express HCAs, because for those HCAs, the driver uses the value of pdev->irq before pci_enable_msi() and ends up getting a totally bogus IRQ number.

* [PATCH] LOG2: Implement a general integer log2 facility in the kernelDavid Howells2006-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This facility provides three entry points: ilog2() Log base 2 of unsigned long ilog2_u32() Log base 2 of u32 ilog2_u64() Log base 2 of u64 These facilities can either be used inside functions on dynamic data: int do_something(long q) { ...; y = ilog2(x) ...; } Or can be used to statically initialise global variables with constant values: unsigned n = ilog2(27); When performing static initialisation, the compiler will report "error: initializer element is not constant" if asked to take a log of zero or of something not reducible to a constant. They treat negative numbers as unsigned. When not dealing with a constant, they fall back to using fls() which permits them to use arch-specific log calculation instructions - such as BSR on x86/x86_64 or SCAN on FRV - if available.

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.
