* [SPARC64]: Initial sun4v TLB miss handling infrastructure.David S. Miller2006-03-202-2/+17
| | | | | | | | | | Things are a little tricky because, unlike sun4u, we have to: 1) do a hypervisor trap to do the TLB load. 2) do the TSB lookup calculations by hand Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Sanitize %pstate writes for sun4v.David S. Miller2006-03-201-0/+6
| | | | | | | | If we're just switching between different alternate global sets, nop it out on sun4v. Also, get rid of all of the alternate global save/restore in the OBP CIF trampoline code. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Kill all %pstate changes in context switch code.David S. Miller2006-03-201-5/+0Star
| | | | | | | | | | | | | | | They are totally unnecessary because: 1) Interrupts are already disabled when switch_to() runs. 2) We don't use hard-coded alternate globals any longer. This found a case in rtrap, which still assumed alternate global %g6 was current_thread_info(), and that is fixed by this changeset as well. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | When saving and restoing trap state, do the window spill/fill handling inline so that we never trap deeper than 2 trap levels. This is important for chips like Niagara.

* [SPARC64]: Refine code sequences to get the cpu id.David S. Miller2006-03-203-47/+71
| | | | | | | | | | | | | | | | | | On uniprocessor, it's always zero for optimize that. On SMP, the jmpl to the stub kills the return address stack in the cpu branch prediction logic, so expand the code sequence inline and use a code patching section to fix things up. This also always better and explicit register selection, which will be taken advantage of in a future changeset. The hard_smp_processor_id() function is big, so do not inline it. Fix up tests for Jalapeno to also test for Serrano chips too. These tests want "jbus Ultra-IIIi" cases to match, so that is what we should test for. Signed-off-by: David S.

* [SPARC64]: Correctable ECC errors cannot occur at trap level > 0.David S. Miller2006-03-201-6/+3Star
| | | | | | | | | | | | | The are distrupting, which by the sparc v9 definition means they can only occur when interrupts are enabled in the %pstate register. This never occurs in any of the trap handling code running at trap levels > 0. So just mark it as an unexpected trap. This allows us to kill off the cee_stuff member of struct thread_info.

* [SPARC64]: Access TSB with physical addresses when possible.David S. Miller2006-03-202-6/+91
| | | | | | | | | | | | | This way we don't need to lock the TSB into the TLB. The trick is that every TSB load/store is registered into a special instruction patch section. The default uses virtual addresses, and the patch instructions use physical address load/stores. We can't do this on all chips because only cheetah+ and later have the physical variant of the atomic quad load. Signed-off-by: David S. Miller <davem@davemloft.net>

* [SPARC64]: Add infrastructure for dynamic TSB sizing.David S. Miller2006-03-203-6/+24
| | | | | | | | | | | | | | | This also cleans up tsb_context_switch(). The assembler routine is now __tsb_context_switch() and the former is an inline function that picks out the bits from the mm_struct and passes it into the assembler code as arguments. setup_tsb_parms() computes the locked TLB entry to map the TSB. Later when we support using the physical address quad load instructions of Cheetah+ and later, we'll simply use the physical address for the TSB register value and set the map virtual and PTE both to zero.

* [SPARC64]: Elminate all usage of hard-coded trap globals.David S. Miller2006-03-203-11/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | UltraSPARC has special sets of global registers which are switched to for certain trap types. There is one set for MMU related traps, one set of Interrupt Vector processing, and another set (called the Alternate globals) for all other trap types. For what seems like forever we've hard coded the values in some of these trap registers. Some examples include: 1) Interrupt Vector global %g6 holds current processors interrupt work struct where received interrupts are managed for IRQ handler dispatch. 2) MMU global %g7 holds the base of the page tables of the currently active address space. 3) Alternate global %g6 held the current_thread_info() value. Such hardcoding has resulted in some serious issues in many areas. There are some code sequences where having another register available would help clean up the implementation. Taking traps such as cross-calls from the OBP firmware requires some trick code sequences wherein we have to save away and restore all of the special sets of global registers when we enter/exit OBP. We were also using the IMMU TSB register on SMP to hold the per-cpu area base address, which doesn't work any longer now that we actually use the TSB facility of the cpu. The implementation is pretty straight forward. One tricky bit is getting the current processor ID as that is different on different cpu variants. We use a stub with a fancy calling convention which we patch at boot time. The calling convention is that the stub is branched to and the (PC - 4) to return to is in register %g1. The cpu number is left in %g6. This stub can be invoked by using the __GET_CPUID macro. We use an array of per-cpu trap state to store the current thread and physical address of the current address space's page tables. The TRAP_LOAD_THREAD_REG loads %g6 with the current thread from this table, it uses __GET_CPUID and also clobbers %g1. TRAP_LOAD_IRQ_WORK is used by the interrupt vector processing to load the current processor's IRQ software state into %g6. It also uses __GET_CPUID and clobbers %g1. Finally, TRAP_LOAD_PGD_PHYS loads the physical address base of the current address space's page tables into %g7, it clobbers %g1 and uses __GET_CPUID. Many refinements are possible, as well as some tuning, with this stuff in place. Signed-off-by: David S. Miller <davem@davemloft.net>

* [SPARC64]: Move away from virtual page tables, part 1.David S. Miller2006-03-207-57/+204
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We now use the TSB hardware assist features of the UltraSPARC MMUs. SMP is currently knowingly broken, we need to find another place to store the per-cpu base pointers. We hid them away in the TSB base register, and that obviously will not work any more :-) Another known broken case is non-8KB base page size. Also noticed that flush_tlb_all() is not referenced anywhere, only the internal __flush_tlb_all() (local cpu only) is used by the sparc64 port, so we can get rid of flush_tlb_all(). The kernel gets it's own 8KB TSB (swapper_tsb) and each address space gets it's own private 8K TSB. Later we can add code to dynamically increase the size of per-process TSB as the RSS grows. An 8KB TSB is good enough for up to about a 4MB RSS, after which the TSB starts to incur many capacity and conflict misses. We even accumulate OBP translations into the kernel TSB. Another area for refinement is large page size support. We could use a secondary address space TSB to handle those. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From Dave Johnson <djohnson+linuxmips@sw.starentnetworks.com>: sb1250_gettimeoffset() simply reads the current cpu 0 timer remaining value, however once this counter reaches 0 and the interrupt is raised, it immediately resets and begins to count down again. If sb1250_gettimeoffset() is called on cpu 1 via do_gettimeofday() after the timer has reset but prior to cpu 0 processing the interrupt and taking write_seqlock() in timer_interrupt() it will return a full value (or close to it) causing time to jump backwards 1ms. Once cpu 0 handles the interrupt and timer_interrupt() gets far enough along it will jump forward 1ms. Fix this problem by implementing mips_hpt_*() on sb1250 using a spare timer unrelated to the existing periodic interrupt timers. It runs at 1Mhz with a full 23bit counter. This eliminated the custom do_gettimeoffset() for sb1250 and allowed use of the generic fixed_rate_gettimeoffset() using mips_hpt_*() and timerhi/timerlo.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch '[PATCH] RCU signal handling' [1] added an export for __put_task_struct_cb, a put_task_struct helper newly introduced in that patch. But the put_task_struct couldn't be used modular previously as __put_task_struct wasn't exported. There are not callers of it in modular code, and it shouldn't be exported because we don't want drivers to hold references to task_structs.

* | [PATCH] slab: Node rotor for freeing alien caches and remote per cpu pages.Christoph Lameter2006-03-101-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cache reaper currently tries to free all alien caches and all remote per cpu pages in each pass of cache_reap. For a machines with large number of nodes (such as Altix) this may lead to sporadic delays of around ~10ms. Interrupts are disabled while reclaiming creating unacceptable delays. This patch changes that behavior by adding a per cpu reap_node variable. Instead of attempting to free all caches, we free only one alien cache and the per cpu pages from one remote node. That reduces the time spend in cache_reap. However, doing so will lengthen the time it takes to completely drain all remote per cpu pagesets and all alien caches. The time needed will grow with the number of nodes in the system. All caches are drained when they overflow their respective capacity. So the drawback here is only that a bit of memory may be wasted for awhile longer. Details: 1. Rename drain_remote_pages to drain_node_pages to allow the specification of the node to drain of pcp pages. 2. Add additional functions init_reap_node, next_reap_node for NUMA that manage a per cpu reap_node counter. 3. Add a reap_alien function that reaps only from the current reap_node. For us this seems to be a critical issue. Holdoffs of an average of ~7ms cause some HPC benchmarks to slow down significantly. F.e. NAS parallel slows down dramatically. NAS parallel has a 12-16 seconds runtime w/o rotor compared to 5.8 secs with the rotor patches. It gets down to 5.05 secs with the additional interrupt holdoff reductions.
