* [PATCH] powerpc: Merge vdso's and add vdso support to 32 bits kernelBenjamin Herrenschmidt2005-11-1134-356/+1421
| | | | | | | | | | | | | | | | | | | | | This patch moves the vdso's to arch/powerpc, adds support for the 32 bits vdso to the 32 bits kernel, rename systemcfg (finally !), and adds some new (still untested) routines to both vdso's: clock_gettime() with support for CLOCK_REALTIME and CLOCK_MONOTONIC, clock_getres() (same clocks) and get_tbfreq() for glibc to retreive the timebase frequency. Tom,Steve: The implementation of get_tbfreq() I've done for 32 bits returns a long long (r3, r4) not a long. This is such that if we ever add support for >4Ghz timebases on ppc32, the userland interface won't have to change. I have tested gettimeofday() using some glibc patches in both ppc32 and ppc64 kernels using 32 bits userland (I haven't had a chance to test a 64 bits userland yet, but the implementation didn't change and was tested earlier). I haven't tested yet the new functions. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

* [PATCH] powerpc: Move udbg code to arch/powerpcDavid Gibson2005-11-115-8/+5
| | | | | | | | | | | | | | | | | Since the udbg code in ppc64 has no ppc32 equivalent, move it straight over into arch/powerpc (and include/asm-powerpc for udbg.h). In time, we probably want to meld the various bits and pieces of 32-bit early debugging code into udbg, but for now only include it on CONFIG_PPC64=y builds. The only change during the move is to standardise the protecting #ifdef/#define in udbg.h, and move its banner comment above the initial #ifdef (which seems to be normal practice). Built and booted on POWER5 LPAR (ARCH=powerpc and ARCH=ppc64). Built for 32bit multiplatform (ARCH=powerpc).

* [PATCH] ppc64: Convert NUMA to sparsemem (3)Anton Blanchard2005-11-113-222/+165
| | | | | | | | | | | | | | | | Convert to sparsemem and remove all the discontigmem code in the process. This has a few advantages: - The old numa_memory_lookup_table can go away - All the arch specific discontigmem magic can go away We also remove the triple pass of memory properties and instead create a list of per node extents that we iterate through. A final cleanup would be to change our lmb code to store extents per node, then we can reuse that information in the numa code.

* [PATCH] PCI: fix for Toshiba ohci1394 quirkJesse Barnes2005-11-101-2/+1
| | | | | | | | | | | | | | | | | | | | | After much testing and agony, I've discovered that my previous ohci1394 quirk for Toshiba laptops is not 100% reliable. It apparently fails to do the interrupt line change either correctly or in time, since in about 2 out of 5 boots, the kernel's irqdebug code will *still* disable irq 11 when the ohci1394 driver is loaded (at pci_enable_device time I think). This patch switches things around a little in the workaround. First, it removes the mdelay. I didn't see a need for it and my testing has shown that it's not necessary for the quirk to work. Secondly, instead of trying to change the interrupt line to what ACPI tells us it should be, this patch makes the quirk use the value in the PCI_INTERRUPT_LINE register. On this laptop at least, that seems to be the right thing to do, though additional testing on other laptops and/or with actual firewire devices would be appreciated.

We need multiple notification points for these events because they can take many seconds to run which has nasty effects on the behaviour of the rest of the system. DIE_SS replaced by a generic DIE_FAULT which checks the vector number, to allow interception of faults other than SS. DIE_MACHINE_{HALT,RESTART} added to allow last minute close down processing, especially when the halt/restart routines are called from error handlers. DIE_OOPS added. The check for kprobe's break numbers has been moved from traps.c to kprobes.c, allowing DIE_BREAK to be used for any additional break numbers, i.e. it is no longer kprobes specific. Hooks for kernel debuggers and kernel dumpers added, ENTER and LEAVE. Both of these disable the system for long periods which impact on watchdogs and heartbeat systems in general. More patches to come that use these events to reset watchdogs and heartbeats. unregister_die_notifier() added and both routines exported. Requested by Dean Nelson. Lock removed from {un,}register_die_notifier. notifier_chain_register() already takes a lock. Also the generic notifier chain locking is being reworked to distinguish between callbacks that can block and those that cannot, the lock in {un,}register_die_notifier would interfere with that change. http://marc.theaimsgroup.com/?l=linux-kernel&m=113018709002036&w=2 Leading white space removed from arch/ia64/kernel/kprobes.c.

The driver is complex for several reasons. Battery charging is manually monitored and controlled. When suspended, the device needs to periodically partially resume, check the charging status and then re-suspend. It does without bothering the higher linux layers as a full resume and re-suspend is unnecessary. The code is carefully written to avoid interrupts or calling code outside the module under these circumstances. It also vets the various wake up sources and monitors the device's power situation. Hooks to limit the backlight intensity and to notify the battery monitoring code of backlight events are connected/added as the backlight is one of the biggest users of power on the device.

The LinkSys NSLU2 is a cost engineered ARM, XScale 420 based system similar to the the Intel IXDP425 evaluation board. It uses the IXP4XX ARCH. While this patch applies independently of other patches the resultant kernel requires further patches to successfully use onboard devices, including the onboard flash. Since these patches are independent of this one they will be submitted separately. A defconfig is not included here because not all of the required drivers are actually in the kernel. We intend to provide one as soon as the patches will be incorporated in mainstream.

In order to avoid repeated reports of a failure, the entire tree of affected devices should be marked as failed. This patch marks up the entire tree.

The file affected are: hvcall.h proc_ppc64.c sysfs.c lparcfg.c rtas_pci.c The only changes apart from the move and corresponding Makefile changes are: - #ifndef/#define in includes updated to _ASM_POWERPC_ form - trailing whitespace removed - comments giving full paths removed Built and booted on POWER5 LPAR (ARCH=powerpc and ARCH=ppc64), built for 32-bit powermac (ARCH=powerpc).

| * | | | | [PATCH] ppc64: fix PCI IO mappingBenjamin Herrenschmidt2005-11-104-7/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | phbs_remap_io(), which maps the PCI IO space into the kernel virtual space, is called too early on powermac, and thus doesn't work. This fixes it by removing the call from all platforms and putting it back into the ppc64 common code where it belongs, after the actual probing of the bus. That means that before that call, only the ISA IO space (if any) is mapped, any PIO access (from quirks for example) will fail. This happens not to be a problem for now, but we'll have to rework that code if it becomes one in the future.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | That DART (U3 iommu) code didn't properly scale the number of entries when using !4k pages. That caused crashes when booting G5s with more than 2Gb of RAM. This fixes it. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
