| * [POWERPC] 83xx/85xx: Reorganize defconfigsKumar Gala2008-04-17
| | | | | | | | | | | | | | | | | | | | Board specific defconfigs are useful, however with the ability to do multi-board defconfigs they aren't needed in the top level configs directory Move the 83xx/85xx board specific defconfigs to individual directories under arch/powerpc/configs.

| * [POWERPC] Rework Book-E debug exception handlingKumar Gala2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The architecture allows for "Book-E" style debug interrupts to either go to critial interrupts of their own debug interrupt level. To allow for a dynamic kernel to support machines of either type we want to be able to compile in the interrupt handling code for both exception levels. Towards this goal we renamed the debug handling macros to specify the interrupt level in their name (DEBUG_CRIT_EXCEPTION/DebugCrit and DEBUG_DEBUG_EXCEPTION/DebugDebug). Additionally, on the Freescale Book-e parts we expanded the exception stacks to cover the maximum case of needing three exception stacks (normal, machine check and debug). There is some kernel text space optimization to be gained if a kernel is configured for a specific Freescale implementation but we aren't handling that now to allow for the single kernel image support.

| * [POWERPC] spufs: fix incorrect file descriptors in SPU coredump note namesGerhard Stenzel2008-03-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present, ppu-gdb can't trace spu infomation with coredump generated by the kernel. While the core dumps notes have correct contents, they have the wrong names, as the file descriptors used to generate the note names are off-by-one. An application that opens a SPE context as fd 3, the current core dump code will generate notes like: SPU/4/mem SPU/4/regs etc. This confuses GDB, which knows it is looking for SPE context 3 (from parsing the spu_context_run system call arguments), and cannot find any notes that match context 3. This change corrects the file descriptor counting, to only increment the fd until after we've written the note name.

| * [POWERPC] spufs: save MFC command channel before purging MFC queueJeremy Kerr2008-03-27
| | | | | | | | | | | | | | | | | | | | During the context save process, we currently save the MFC command channel after purging the MFC queues. This causes a systemsim warning, as the command channel may be in an unknown state after the purge. This change does the save before purging the MFC queues. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
| * [POWERPC] spufs: reacquire LS pointer in spu_process_callbackJeremy Kerr2008-03-27
| | | | | | | | | | | | | | | | | | | | | | During spu_process callback, we release then acquire the SPU, but keep a pointer to the local store memory. Since the context may have been scheduled out during the callback, the ls pointer may become invalid. This change reacquires the pointer to the context local store after spu_acquire()-ing, so that it isn't invalidated by a context switch. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>

* | [POWERPC] Remove unused machine call outsKumar Gala2008-04-16
| | | | | | | | | | | | | | | | | | | | | | | | When we moved to arch/powerpc we actively tried to avoid using the ppc_md.setup_io_mappings(). Currently no board ports use it so let's remove it to avoid any new boards using it. Also, remove early_serial_map() since we don't even have a call out for it in arch/powerpc.

* | [POWERPC] Always add preferred consoles in platforms/pseries/lpar.cMichael Ellerman2008-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is logic in platforms/peries/lpars.c which checks if the user has specified a console on the command line, and refrains from adding a preferred console entry for the hvc/hvsi console if they have. This trips up if you use "netconsole=foo" on the command line, and has the result that you get _only_ the netconsole, because the hvc device is never added as a preferred console. Worse still if you get the netconsole configuration wrong somehow, you end up with no console at all. As it turns out we don't need to worry about checking the command line. If the user has specified "console=foo", then foo will be set as the preferred console when the command line is parsed in start_kernel(), much later than the pseries code, and so the latter setting will take effect.

* | [POWERPC] pseries/phyp dump: Reserve a variable amount of space at bootManish Ahuja2008-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes the way we calculate how much space to reserve for the pHyp dump. Currently we reserve 256MB only. With this change, the code first checks to see if an amount has been specified on the boot command line with the "phyp_dump_reserve_size" option, and if so, uses that much. Otherwise it computes 5% of total ram and rounds it down to a multiple of 256MB, and uses the larger of that or 256MB. This is for large systems with a lot of memory (10GB or more). The aim is to have more space available for the kernel on reboot on machines with more resources. Although the dump will be collected pretty fast and the memory released really early on allowing the machine to have the full memory available, this alleviates any issues that can be caused by having way too little memory on very very large systems during those few minutes.

* | [POWERPC] bootwrapper: Use physical address in PHDR for uImageKumar Gala2008-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we properly set the physical address in the program header of the vmlinux ELF we can extract it to properly set the load and entry point for u-boot uImages. Before we always hard coded the load & entry point to 0. However there are situations that the kernel may be built with a non-zero physical address. We use objdump to extract the PHDR. We assume that there is only one PHDR in the vmlinux of type LOAD. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
* | [POWERPC] Update linker script to properly set physical addressesKumar Gala2008-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We can set LOAD_OFFSET and use the AT attribute on sections and the linker will properly set the physical address of the LOAD program header for us. This allows us to know how the PHYSICAL_START the user configured a kernel with by just looking at the resulting vmlinux ELF.

* | [POWERPC] Move phys_addr_t definition into asm/types.hKumar Gala2008-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Moved phys_addr_t out of mmu-*.h and into asm/types.h so we can use it in places that before would have caused recursive includes. For example to use phys_addr_t in <asm/page.h> we would have included <asm/mmu.h> which would have possibly included <asm/mmu-hash64.h> which includes <asm/page.h>. Wheeee recursive include. CONFIG_PHYS_64BIT is a bit counterintuitive in light of ppc64 systems and thus the config option is only used for ppc32 systems with >32-bit physical addresses (44x, 85xx, 745x, etc.).

* | [POWERPC] Introduce lowmem_end_addr to distinguish from total_lowmemKumar Gala2008-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | total_lowmem represents the amount of low memory, not the physical address that low memory ends at. If the start of memory is at 0 it happens that total_lowmem can be used as both the size and the address that lowmem ends at (or more specifically one byte beyond the end). To make the code a bit more clear and deal with the case when the start of memory isn't at physical 0, we introduce lowmem_end_addr that represents one byte beyond the last physical address in the lowmem region.

* | [POWERPC] Remove and replace uses of PPC_MEMSTART with memstart_addrKumar Gala2008-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A number of users of PPC_MEMSTART (40x, ppc_mmu_32) can just always use 0 as we don't support booting these kernels at non-zero physical addresses since their exception vectors must be at 0 (or 0xfffx_xxxx). For the sub-arches that support relocatable interrupt vectors (book-e), it's reasonable to have memory start at a non-zero physical address. For those cases use the variable memstart_addr instead of the #define PPC_MEMSTART since the only uses of PPC_MEMSTART are for initialization and in the future we can set memstart_addr at runtime to have a relocatable kernel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fedora 9 works on Efika without the separate 'device-tree supplement', thanks to the kernel's own fixups. With one exception -- because 'CHRP' still appears on the 'machine:' line in /proc/cpuinfo, the installer misdetects the platform and misconfigures yaboot, putting it into a PReP boot partition instead of in the /boot filesystem where the Efika's firmware could find it. The kernel's fixups for Efika already correct one instance of 'chrp', in the 'device_type' property. This fixes it in the 'CODEGEN,description' property too, since that's what's exposed to userspace in /proc/cpuinfo.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the handling of the preempt count when switching interrupt stacks so that HW interrupt properly get the softirq mask copied over from the previous stack. It also initializes the softirq stack preempt_count to 0 instead of SOFTIRQ_OFFSET, like x86, as __do_softirq() does the increment, and we hit some lockdep checks if we have it twice. That means we do run for a little while off the softirq stack with the preempt-count set to 0, which could be deadly if we try to take a softirq at that point, however we do so with interrupts disabled, so I think we are ok.

* | [POWERPC] Initialize paca->current earlierBenjamin Herrenschmidt2008-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, we initialize the "current" pointer in the PACA (which is used by the "current" macro in the kernel) before calling setup_system(). That means that early_setup() is called with current still "NULL" which is -not- a good idea. It happens to work so far but breaks with lockdep when early code calls printk. This changes it so that all PACAs are statically initialized with __current pointing to the init task. For non-0 CPUs, this is fixed up before use.

In fact it probably isn't possible to hit the bug in practice since it would only occur in the situation where we can't satisfy the allocation request and there is a reserved region starting at 0. This fixes the potential bug by breaking out of the loop when we get to the point where the base of the reserved region is less than the size requested. This also restructures the loop to be a bit easier to follow. The same logic got copied into lmb_alloc_nid_unreserved, so this makes a similar change there. Here the bug is more likely to be hit because the outer loop (in lmb_alloc_nid) goes through the memory regions in increasing order rather than decreasing order as __lmb_alloc_base does, and we are therefore more likely to hit the case where we are testing against a reserved region with a base address of 0.

The caller provides a 'nid_range' function pointer which assists the allocator. It is given args 'start', 'end', and pointer to integer 'this_nid'. It places at 'this_nid' the NUMA node id that corresponds to 'start', and returns the end address within 'start' to 'end' at which memory assosciated with 'nid' ends. This callback allows a platform to use lmb_alloc_nid() in just about any context, even ones in which early_pfn_to_nid() might not be working yet. This function will be used by the NUMA setup code on sparc64, and also it can be used by powerpc, replacing it's hand crafted "careful_allocation()" function in arch/powerpc/mm/numa.c If x86 ever converts it's NUMA support over to using the LMB helpers, it can use this too as it has something entirely similar.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we have the alpaca, the reg_save_ptr is no longer needed in the paca. Eradicate all global uses of it and make it static in the iSeries lpardata.c Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
* | | [POWERPC] iSeries: Use alternate paca structure for bootingStephen Rothwell2008-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The iSeries HV only needs the first two fields of the paca statically initialised, so create an alternate paca that contains only those and switch to our real paca immediately after boot. This is in order to make the 1024 cpu patches easier since they will no longer have to statically initialise the pacas for iSeries.
