2008-04-22[IA64] minor irq handler cleanupsJeff Garzik
- remove unused 'irq' argument from pfm_do_interrupt_handler() - remove pointless cast to void* - add KERN_xxx prefix to printk() - remove braces around singleton C statement - in tioce_provider.c, start tioce_dma_consistent() and tioce_error_intr_handler() function declarations in column 0 This change's main purpose is to prepare for the patchset in jgarzik/misc-2.6.git#irq-remove, that explores removal of the never-used 'irq' argument in each interrupt handler.

2008-04-22[IA64] disable interrupts on exit of ia64_trace_syscallHidetoshi Seto
While testing with CONFIG_VIRT_CPU_ACCOUNTING=y, I found that I occasionally get very huge system time in some threads. So I dug the issue and finally noticed that it was caused because of an interrupt which interrupt in the following window: > [arch/ia64/kernel/entry.S: (!CONFIG_PREEMPT && CONFIG_VIRT_CPU_ACCOUNTING)] > > ENTRY(ia64_leave_syscall) > : > (pUStk) rsm psr.i > cmp.eq pLvSys,p0=r0,r0 // pLvSys=1: leave from syscall > (pUStk) cmp.eq.unc p6,p0=r0,r0 // p6 <- pUStk > .work_processed_syscall: > adds r2=PT(LOADRS)+16,r12 > (pUStk) mov.m r22=ar.itc // fetch time at leave > adds r18=TI_FLAGS+IA64_TASK_SIZE,r13 > ;; > <<< window: from here >>> > (p6) ld4 r31=[r18] // load current_thread_info()->flags > ld8 r19=[r2],PT(B6)-PT(LOADRS) > adds r3=PT(AR_BSPSTORE)+16,r12 > ;; > mov r16=ar.bsp > ld8 r18=[r2],PT(R9)-PT(B6) > (p6) and r15=TIF_WORK_MASK,r31 // any work other than TIF_SYSCALL_TRACE? > ;; > ld8 r23=[r3],PT(R11)-PT(AR_BSPSTORE) > (p6) cmp4.ne.unc p6,p0=r15, r0 // any special work pending? > (p6) br.cond.spnt .work_pending_syscall > ;; > ld8 r9=[r2],PT(CR_IPSR)-PT(R9) > ld8 r11=[r3],PT(CR_IIP)-PT(R11) > (pNonSys) break 0 // bug check: we shouldn't be here if pNonSys is TRUE! > ;; > invala > <<< window: to here >>> > rsm psr.i | psr.ic // turn off interrupts and interruption collection If pUStk is true, it means we are going to return user mode, hence we fetch ar.itc to get time at leave from system. It seems that it is not possible to interrupt the window if pUStk is true, because interrupts are disabled early. And also disabling interrupt makes sense because it is safe for referring current_thread_info()->flags. However interrupting the window while pUStk is true was possible. The route was: ia64_trace_syscall -> .work_pending_syscall_end -> .work_processed_syscall Only in case entering the window from this route, interrupts are enabled during in the window even if pUStk is true. I suppose interrupts must be disabled here anyway if pUStk is true. I'm not sure but afraid that what kind of bad effect were there, other than crazy system time which I found. FYI, there was a commit 6f6d75825dc49b082906b84537b4df28293c2977 that points out a bug at same point(exit of ia64_trace_syscall) in 2006. It can be said that there was an another bug.

The PCI bus names included in /proc/iomem and /proc/ioports are of the form 'PCI Bus #XX' where XX is the bus number. This patch changes the naming to 'PCI Bus XXXX:YY' where XXXX is the domain number and YY is the bus number. For example, PCI bus 14 in domain 0 will show as 'PCI Bus 0000:14' instead of 'PCI Bus #14'. This change makes the naming consistent with other architectures such as ia64 where multiple PCI domain support has been around longer.

2008-04-20PCI: remove pcibios_fixup_ghosts()Greg Kroah-Hartman
This function was obviously never being used since early 2.5 days as any device that it would try to remove would never really be removed from the system due to the PCI device list being held in the driver core, not the general list of PCI devices. As we have not had a single report of a problem here in 4 years, I think it's safe to remove now. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2008-04-20PCI: remove initial bios sort of PCI devices on x86Greg Kroah-Hartman
We currently keep 2 lists of PCI devices in the system, one in the driver core, and one all on its own. This second list is sorted at boot time, in "BIOS" order, to try to remain compatible with older kernels (2.2 and earlier days). There was also a "nosort" option to turn this sorting off, to remain compatible with even older kernel versions, but that just ends up being what we have been doing from 2.5 days... Unfortunately, the second list of devices is not really ever used to determine the probing order of PCI devices or drivers[1]. That is done using the driver core list instead. This change happened back in the early 2.5 days. Relying on BIOS ording for the binding of drivers to specific device names is problematic for many reasons, and userspace tools like udev exist to properly name devices in a persistant manner if that is needed, no reliance on the BIOS is needed. Matt Domsch and others at Dell noticed this back in 2006, and added a boot option to sort the PCI device lists (both of them) in a breadth-first manner to help remain compatible with the 2.4 order, if needed for any reason. This option is not going away, as some systems rely on them. This patch removes the sorting of the internal PCI device list in "BIOS" mode, as it's not needed at all anymore, and hasn't for many years. I've also removed the PCI flags for this from some other arches that for some reason defined them, but never used them. This should not change the ordering of any drivers or device probing. [1] The old-style pci_get_device and pci_find_device() still used this sorting order, but there are very few drivers that use these functions, as they are deprecated for use in this manner. If for some reason, a driver rely on the order and uses these functions, the breadth-first boot option will resolve any problem.

Define the copy_siginfo_from_user32 entry point for powerpc, so that generic CONFIG_COMPAT code can call it. We already had the code rolled into compat_sys_rt_sigqueueinfo, this just moves it out into the canonical function that other arch's define.

2008-04-19PM: Remove destroy_suspended_device()Rafael J. Wysocki
After 2.6.24 there was a plan to make the PM core acquire all device semaphores during a suspend/hibernation to protect itself from concurrent operations involving device objects. That proved to be too heavy-handed and we found a better way to achieve the goal, but before it happened, we had introduced the functions device_pm_schedule_removal() and destroy_suspended_device() to allow drivers to "safely" destroy a suspended device and we had adapted some drivers to use them. Now that these functions are no longer necessary, it seems reasonable to remove them and modify their users to use the normal device unregistration instead. Signed-off-by: Rafael J.

2008-04-19Firmware: add iSCSI iBFT SupportKonrad Rzeszutek
Add /sysfs/firmware/ibft/[initiator|targetX|ethernetX] directories along with text properties which export the the iSCSI Boot Firmware Table (iBFT) structure. What is iSCSI Boot Firmware Table? It is a mechanism for the iSCSI tools to extract from the machine NICs the iSCSI connection information so that they can automagically mount the iSCSI share/target. Currently the iSCSI information is hard-coded in the initrd. The /sysfs entries are read-only one-name-and-value fields. The usual set of data exposed is: # for a in `find /sys/firmware/ibft/ -type f -print`; do echo -n "$a: "; cat $a; done /sys/firmware/ibft/target0/target-name: iqn.2007.com.intel-sbx44:storage-10gb /sys/firmware/ibft/target0/nic-assoc: 0 /sys/firmware/ibft/target0/chap-type: 0 /sys/firmware/ibft/target0/lun: 00000000 /sys/firmware/ibft/target0/port: 3260 /sys/firmware/ibft/target0/ip-addr: 192.168.79.116 /sys/firmware/ibft/target0/flags: 3 /sys/firmware/ibft/target0/index: 0 /sys/firmware/ibft/ethernet0/mac: 00:11:25:9d:8b:01 /sys/firmware/ibft/ethernet0/vlan: 0 /sys/firmware/ibft/ethernet0/gateway: 192.168.79.254 /sys/firmware/ibft/ethernet0/origin: 0 /sys/firmware/ibft/ethernet0/subnet-mask: 255.255.252.0 /sys/firmware/ibft/ethernet0/ip-addr: 192.168.77.41 /sys/firmware/ibft/ethernet0/flags: 7 /sys/firmware/ibft/ethernet0/index: 0 /sys/firmware/ibft/initiator/initiator-name: iqn.2007-07.com:konrad.initiator /sys/firmware/ibft/initiator/flags: 3 /sys/firmware/ibft/initiator/index: 0 For full details of the IBFT structure please take a look at: ftp://ftp.software.ibm.com/systems/support/system_x_pdf/ibm_iscsi_boot_firmware_table_v1.02.pdf [akpm@linux-foundation.org: fix build] Signed-off-by: Konrad Rzeszutek <konradr@linux.vnet.ibm.com> Cc: Mike Christie <michaelc@cs.wisc.edu> Cc: Peter Jones <pjones@redhat.com> Cc: James Bottomley <James.Bottomley@HansenPartnership.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2008-04-19avr32: Implement set_rate(), set_parent() and mode() for pll1Hans-Christian Egtvedt
This patch is a take two of adding full functionality to PLL1 on AT32AP7000. This allows board-specific code and drivers to configure and enable PLL1. This is useful when precise control over the frequency of e.g. a genclock is needed and requested by users for the ABDAC device. The patch is based upon previous patches from both Haavard Skinnemoen and David Brownell.

2008-04-19avr32: Generic clockevents supportDavid Brownell
This combines three patches from David Brownell: * avr32: tclib support * avr32: simplify clocksources * avr32: Turn count/compare into a oneshot clockevent device Register both TC blocks (instead of just the first one) so that the AT32/AT91 tclib code will pick them up (instead of just the avr32-only PIT-style clocksource). Rename the first one and its resources appropriately. More cleanups to the cycle counter clocksource code - Disable all the weak symbol magic; remove the AVR32-only TCB-based clocksource code (source and header). - Mark the __init code properly. - Don't forget to report IRQF_TIMER. - Make the system work properly with this clocksource, by preventing use of the CPU "idle" sleep state in the idle loop when it's used. Package the avr32 count/compare timekeeping support as a oneshot clockevent device, so it supports NO_HZ and high res timers. This means it also supports plugging in other clockevent devices and clocksources.
