* | [PATCH] knfsd: tidy up up meaning of 'buffer size' in nfsd/sunrpcNeilBrown2006-10-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is some confusion about the meaning of 'bufsz' for a sunrpc server. In some cases it is the largest message that can be sent or received. In other cases it is the largest 'payload' that can be included in a NFS message. In either case, it is not possible for both the request and the reply to be this large. One of the request or reply may only be one page long, which fits nicely with NFS. So we remove 'bufsz' and replace it with two numbers: 'max_payload' and 'max_mesg'. Max_payload is the size that the server requests. It is used by the server to check the max size allowed on a particular connection: depending on the protocol a lower limit might be used. max_mesg is the largest single message that can be sent or received. It is calculated as the max_payload, rounded up to a multiple of PAGE_SIZE, and with PAGE_SIZE added to overhead. Only one of the request and reply may be this size. The other must be at most one page. Cc: Greg Banks <gnb@sgi.com> Cc: "J.

* | [PATCH] page fault retry with NOPAGE_REFAULTBenjamin Herrenschmidt2006-10-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a way for a no_page() handler to request a retry of the faulting instruction. It goes back to userland on page faults and just tries again in get_user_pages(). I added a cond_resched() in the loop in that later case. The problem I have with signal and spufs is an actual bug affecting apps and I don't see other ways of fixing it. In addition, we are having issues with infiniband and 64k pages (related to the way the hypervisor deals with some HV cards) that will require us to muck around with the MMU from within the IB driver's no_page() (it's a pSeries specific driver) and return to the caller the same way using NOPAGE_REFAULT. And to add to this, the graphics folks have been following a new approach of memory management that involves transparently swapping objects between video ram and main meory. To do that, they need installing PTEs from a no_page() handler as well and that also requires returning with NOPAGE_REFAULT. (For the later, they are currently using io_remap_pfn_range to install one PTE from no_page() which is a bit racy, we need to add a check for the PTE having already been installed afer taking the lock, but that's ok, they are only at the proof-of-concept stage. I'll send a patch adding a "clean" function to do that, we can use that from spufs too and get rid of the sparsemem hacks we do to create struct page for SPEs. Basically, that provides a generic solution for being able to have no_page() map hardware devices, which is something that I think sound driver folks have been asking for some time too). All of these things depend on having the NOPAGE_REFAULT exit path from no_page() handlers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tim and Ananiev report that the recent WARN_ON_ONCE changes cause increased cache misses with the tbench workload. Apparently due to the access to the newly-added static variable. Rearrange the code so that we don't touch that variable unless the warning is going to trigger. Also rework the logic so that the static variable starts out at zero, so we can move it into bss. It would seem logical to mark the static variable as __read_mostly too. But it would be wrong, because that would put it back into the vmlinux image, and the kernel will never read from this variable in normal operation anyway. Unless the compiler or hardware go and do some prefetching on us? For some reason this patch shrinks softirq.o text by 40 bytes.

| * 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.

| * | [PATCH] x86-64: Calgary IOMMU: Fix off by one when calculating register ↵Jon Mason2006-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | space location The purpose of the code being modified is to determine the location of the calgary chip address space. This is done by a magical formula of FE0MB-8MB*OneBasedChassisNumber+1MB*(RioNodeId-ChassisBase) to find the offset where BIOS puts it. In this formula, OneBasedChassisNumber corresponds to the NUMA node, and rionodeid is always 2 or 3 depending on which chip in the system it is. The problem was that we had an off by one error that caused us to account some busses to the wrong chip and thus give them the wrong address space. Fixes RH bugzilla #203971.

| * | [PATCH] x86-64: Calgary IOMMU: deobfuscate calgary_initJon Mason2006-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | calgary_init's for loop does not correspond to the actual device being checked, which makes its upperbound check for array overflow useless. Changing this to a do-while loop is the correct way of doing this. There should be no possibility of spinning forever in this loop, as pci_get_device states that it will go through all iterations, then return NULL (thus breaking the loop).

* / [PATCH] fix qla{2,4} build errorFrederik Deweerdt2006-10-05
|/ | | | | | | | | | | | | | | | | | | | | | | commit 0181944fe647cae18d545ac1167df3d15d393701 adds a 'extended_error_logging' global variable to qla2xxx which is defined by qla4xxx too. Trying to build both drivers results in the following error: LD drivers/scsi/built-in.o drivers/scsi/qla4xxx/built-in.o: In function `qla4xxx_slave_configure': drivers/scsi/qla4xxx/ql4_os.c:1433: multiple definition of `extended_error_logging' drivers/scsi/qla2xxx/built-in.o:drivers/scsi/qla2xxx/qla_os.c:2166: first defined here make[2]: *** [drivers/scsi/built-in.o] Error 1 make[1]: *** [drivers/scsi] Error 2 make: *** [drivers] Error 2 The following patch simply adds a qla2_ (qla4_ respectively) prefix to the variable name.
