2006-10-06[POWERPC] Minor fix for bootargs propertyGeoff Levand1-1/+1
Avoid the use of an uninitialized stack variable when the powerpc device tree bootargs property is either missing or incorrectly defined. This also makes CONFIG_CMDLINE work properly under these conditions. This change adds a test for the existence of the bootargs property. early_init_dt_scan_chosen() tests for a zero length bootargs property in its CONFIG_CMDLINE processing, but the current implementation of of_get_flat_dt_prop() doesn't assign a value to the length when no property is found. Since an automatic variable is used, a stale value from the stack will be used in the test. Signed-off-by: Geoff Levand <[email protected]> Signed-off-by: Paul Mackerras <[email protected]>

2006-10-06[POWERPC] Don't get PCI IRQ from OF for devices with no IRQBenjamin Herrenschmidt1-6/+11
This patch adds checking of the PCI_INTERRUPT_PIN register before using standard OF parsing to retreive PCI interrupts. The reason is that some PCI devices may have no PCI interrupt, though they may have interrupts attached via other means. In this case, we shall not use irq->pdev, but device-specific code can later retreive those interrupts instead. Without that patch, Maple and derivatives don't get the right interrupt for the second IDE channel as the linux IDE code fallsback to the PCI irq instead of trying to use the legacy ones for the on-board controller (which has no PCI_INTERRUPT_PIN). Having no PCI IRQ assign to it (as it doesn't request any) fixes it. Signed-off-by: Benjamin Herrenschmidt <[email protected]> Signed-off-by: Paul Mackerras <[email protected]>

2006-10-06[POWERPC] linux,tce-size property is 32 bitsNathan Lynch1-1/+2
The "linux,tce-size" property is only 32 bits (see prom_initialize_tce_table() in arch/powerpc/kernel/prom_init.c). Treating it as an unsigned long in iommu_table_setparms() leads to access beyond the end of the property's buffer, so we pass garbage to the memset() in that function.

2006-10-05[PATCH] x86-64: Calgary IOMMU: Fix off by one when calculating register ↵Jon Mason1-2/+11
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.

2006-10-05[PATCH] x86-64: Calgary IOMMU: deobfuscate calgary_initJon Mason1-5/+7
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).

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells44-156/+178
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. Signed-Off-By: David Howells <[email protected]> (cherry picked from 1b16e7ac850969f38b375e511e3fa2f474a33867 commit)
