| * [IA64] Add hotplug cpu to salinfo.c, replace semaphore with mutexKeith Owens2006-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add hotplug cpu support to salinfo.c. The cpu_event field is a cpumask so use the cpu_* macros consistently, replacing the existing mixture of cpu_* and *_bit macros. Instead of counting the number of outstanding events in a semaphore and trying to track that count over user space context, interrupt context, non-maskable interrupt context and cpu hotplug, replace the semaphore with a test for "any bits set" combined with a mutex. Modify the locking to make the test for "work to do" an atomic operation. Signed-off-by: Keith Owens <kaos@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

| * [IA64-SGI] Fix sn_flush_device_kernel & spinlock initializationPrarit Bhargava2006-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch separates the sn_flush_device_list struct into kernel and common (both kernel and PROM accessible) structures. As it was, if the size of a spinlock_t changed (due to additional CONFIG options, etc.) the sal call which populated the sn_flush_device_list structs would erroneously write data (and cause memory corruption and/or a panic). This patch does the following: 1. Removes sn_flush_device_list and adds sn_flush_device_common and sn_flush_device_kernel. 2. Adds a new SAL call to populate a sn_flush_device_common struct per device, not per widget as previously done. 3. Correctly initializes each device's sn_flush_device_kernel spinlock_t struct (before it was only doing each widget's first device).

| * [IA64] Hole in IA64 TLB flushing from system threadsJack Steiner2006-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I originally thought this was an bug only in the SN code, but I think I also see a hole in the generic IA64 tlb code. (Separate patch was sent for the SN problem). It looks like there is a bug in the TLB flushing code. During context switch, kernel threads (kswapd, for example) inherit the mm of the task that was previously running on the cpu. Normally, this is ok because the previous context is still loaded into the RR registers. However, if the owner of the mm migrates to another cpu, changes it's context number, and references a page before kswapd issues a tlb_purge for that same page, the purge will be done with a stale context number (& RR registers).

The OF parsing stuff in arch/powerpc/kernel/prom_parse.c currently doesn't recognize it as a PCI bridge, which means that controlfb.c can't get its device addresses. This makes prom_parse.c recognize a device_type of "vci" as indicating a PCI host bridge. With this, controlfb works again.

| * | | powerpc: Avoid unaligned loads and stores in boot memcpy codePaul Mackerras2006-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 601 processor will generate an alignment exception for accesses which cross a page boundary. In the boot wrapper code, OF is still handling all exceptions, and it doesn't have an alignment exception handler that emulates the instruction and continues. This changes the memcpy and memmove routines in the boot wrapper to avoid doing unaligned accesses. If the source and destination are misaligned with respect to each other, we just copy one byte at a time. Signed-off-by: Paul Mackerras <paulus@samba.org>

It needs to be wrapped in a set of synchronization hypervisor calls (H_Join). When the H_Join calls are made on all CPUs, the intent is that only one will return with H_Continue, meaning that he is the "last man standing". That CPU then issues the ibm,suspend-me call. What is interesting, of course, is that the CPU running when the rtas syscall is made, may NOT be the CPU that ultimately executes the ibm,suspend-me rtas call.

| * | | powerpc: Provide a suitable AT_PLATFORM valuePaul Mackerras2006-01-13

This commit makes the kernel supply an AT_PLATFORM string that indicates what class of processor we are running on. Processors with the same set of user-level instructions and roughly the same instruction scheduling characteristics are given the same AT_PLATFORM value; for example, 821, 823 and 860 are all reported as "ppc823", and 7447, 7447A, 7448, 7450, 7451, 7455 are all called "ppc7450". The intention is that the AT_PLATFORM values match the values that gcc accepts for the -mcpu= option. For values which are numeric (e.g. -mcpu=750), "ppc" has been prepended. This also adds a PPC_FEATURE_BOOKE bit to the AT_HWCAP value and sets it for the 440 family and the Freescale 85xx family. Signed-off-by: Paul Mackerras <paulus@samba.org>

When used to order an unlock operation loads may leak out of the critical region. This is potentially buggy, one example is if a user wants to atomically read a couple of values. We can solve this with an lwsync which orders everything except store - load. I removed the (now unused) EIEIO_ON_SMP macros and the c versions isync_on_smp and eieio_on_smp now we dont use them. I also removed some old comments that were used to identify inline spinlocks in assembly, they dont make sense now our locks are out of line. Another interesting thing was that read_unlock was using an eieio even though the rest of the spinlock code had already been converted to use lwsync.

| * | | [PATCH] powerpc: Remove lppaca structure from the PACADavid Gibson2006-01-13

This doesn't have to be so, the patch below removes it, making a separate array of lppaca structures. This saves approximately 500*NR_CPUS bytes of image size and kernel memory, because we don't need aligning gap between the Linux and hypervisor portions of every PACA. On the other hand it means an extra level of dereference in many accesses to the lppaca. The patch also gets rid of several places where we assign the paca address to a local variable for no particular reason.

The idea is to make the set of macros consistent across 32 and 64 bit and to make it more obvious which is the appropriate one to use in a given situation. The new macros and their semantics are described in the comments in ppc_asm.h. In the process, we change several places that were unnecessarily using immediate loads on ppc64 to use the GOT/TOC. Likewise we cleanup a couple of places where we were clumsily subtracting PAGE_OFFSET with asm instructions to use assemble-time arithmetic or the toreal() macro instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support to reconfigure the device tree through the existing proc filesystem interface. Add "add_property", "remove_property", and "update_property" commands to the existing interface. Signed-off-by: Dave Boutcher <sleddog@us.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add an of_find_property function that returns a struct property given a property name. Then change the get_property function to use that routine internally. Signed-off-by: Dave Boutcher <sleddog@us.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
| * | | [PATCH] powerpc: Add/remove/update properties in firmware device treeDave C Boutcher2006-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for updating and removing device tree properties. Since we hand out pointers to properties with gay abandon, we can't just free the property storage. Instead we move deleted, or the old copy of an updated property, to a "dead properties" list. Also note, its not feasable to kref device tree properties. we call get_property() all over the kernel in a wild variety of contexts. One consequence of this change is that we now take a read_lock(&devtree_lock) when doing get_property().

| * | | [PATCH] powerpc: Add/remove/update properties in /proc/device-treeDave C Boutcher2006-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support to the proc_device_tree file for removing and updating properties. Remove just removes the proc file, update changes the data pointer within the proc file. The remainder of the device-tree changes occur elsewhere.
