This adds support for flash device descriptions to the OF device tree. It's inspired by and partially borrowed from Sergei's patch "[RFC] Adding MTD to device tree.patch". Signed-off-by:

This allows any secondary CPU thread also to become boot cpu for POWER5. The patch is required to solve kdump boot issue when the kdump kernel is booted with parameter "maxcpus=1". XICS init code tries to match the current boot cpu id with "reg" property in each CPU node in the device tree. But CPU node is created only for primary thread CPU ids and "reg" property only reflects primary CPU ids. So when a kernel is booted on a secondary cpu thread above condition will never meet and the default distribution server is left as zero. This leads to route the interrupts to CPU 0, but which is not online at this time. We use ibm,ppc-interrupt-server#s to check for both primary and secondary CPU ids. Accordingly default distribution server value is initialized from "ibm,ppc-interrupt-gserver#s" property. We loop through ibm,ppc-interrupt-gserver#s property to find the global distribution server from the last entry that matches with boot cpuid. Signed-off-by:

At least the ide driver calls pcibus_to_node, which is not defined when CONFIG_PCI is disabled. This adds a nop function for the !PCI case. Signed-off-by:Arnd Bergmann <arnd.bergmann@de.ibm.com>

It's currently not possible to build the default zImage target if PS3 is the only selected platform. This is a hack to fall back to building the pseries style zImage, so the build is successful. This will probably change in the future, if someone writes a PS3 specific boot wrapper. Signed-off-by: -

A few code paths need to check whether or not they are running on the PS3's LV1 hypervisor before making hcalls. This introduces a new firmware feature bit for this, FW_FEATURE_PS3_LV1. Now when both PS3 and IBM_CELL_BLADE are enabled, but not PSERIES, FW_FEATURE_PS3_LV1 and FW_FEATURE_LPAR get enabled at compile time, which is a bug. The same problem can also happen for (PPC_ISERIES && !PPC_PSERIES && PPC_SOMETHING_ELSE). In order to solve this, I introduce a new CONFIG_PPC_NATIVE option that is set when at least one platform is selected that can run without a hypervisor and then turns the firmware feature check into a run-time option. The new cell oprofile support that was recently merged does not work on hypervisor based platforms like the PS3, therefore make it depend on PPC_CELL_NATIVE instead of PPC_CELL. This may change if we get oprofile support for PS3. Signed-off-by: -

It may be desireable to build a kernel for cell without spufs, e.g. as the initial kboot kernel. This requires that the SPU specific parts of the core dump and the xmon code depend on CONFIG_SPU_BASE instead of CONFIG_PPC_CELL. Signed-off-by: -

Currently, we only send a sigtrap if the current task is being ptraced. This is somewhat inconsistant, and it breaks utrace support in fedora. Removing the check should do the right thing in all cases. Cc: Ulrich Weigand <ulrich.weigand@de.ibm.com> Signed-off-by: -

Change the oprofile_cpu_type in cputables.c to be ppc64/970MP. Oprofile needs to distinquish the MP from other 970 processors so it can add some new counters specific to the 970MP. Signed-off-by:

This adds a platform specific spu management abstraction and the coresponding routines to support the IBM Cell Blade. It also removes the hypervisor only resources that were included in struct spu. Three new platform specific routines are introduced, spu_enumerate_spus(), spu_create_spu() and spu_destroy_spu(). The underlying design uses a new type, struct spu_management_ops, to hold function pointers that the platform setup code is expected to initialize to instances appropriate to that platform. For the IBM Cell Blade support, I put the hypervisor only resources that were in struct spu into a platform specific data structure struct spu_pdata. Signed-off-by:

This includes: * version 1.24 of ppc-dis.c * version 1.88 of ppc-opc.c * version 1.23 of ppc.h I can't vouch for the accuracy etc. of these changes, but it brings us into line with binutils - and from a cursory test appears to work fine. Signed-off-by:

While adding spu disassembly support it struck me that we're actually carrying quite a lot of code around, just to do disassembly in the case of a crash. While on large systems it's not an issue, on smaller ones it might be nice to have xmon - but without the weight of the disassembly support. For a Cell build this saves ~230KB (!), and for pSeries ~195KB. We still support the 'di' and 'sdi' commands, however they just dump the instruction in hex. Move the definitions into a header to clean xmon.c just a tiny bit. Signed-off-by:

This patch imports and munges the spu disassembly code from binutils. All files originated from version 1.1 in binutils cvs. * spu.h, spu-insns.h and spu-opc.c are unchanged except for pathnames. * spu-dis.c has been edited heavily: * use printf instead of info->fprintf_func and similar. * pass the instruction in rather than reading it. * we have no equivalent to symbol_at_address_func, so we just assume there is never a symbol at the address given.

In order to do disassembly of spu binaries in xmon, we need to abstract the disassembly function from ppc_inst_dump. We do this by making the actual disassembly function a function pointer that we pass to ppc_inst_dump(). To save updating all the callers, we turn ppc_inst_dump() into generic_inst_dump() and make ppc_inst_dump() a wrapper which always uses print_insn_powerpc(). Currently we pass the dialect into print_insn_powerpc(), but we always pass 0 - so just make it a local. Signed-off-by:

Add a command to xmon to dump the memory of a spu's local store. This mimics the 'd' command which dumps regular memory, but does a little hand holding by taking the user supplied address and finding that offset in the local store for the specified spu. This makes it easy for example to look at what was executing on a spu: 1:mon> ss ... Stopped spu 04 (was running) ... 1:mon> sf 4 Dumping spu fields at address c0000000019e0a00: ... problem->spu_npc_RW = 0x228 ... 1:mon> sd 4 0x228 d000080080318228 01a00c021cffc408 4020007f217ff488 |........@ ..!...| Aha, 01a00c02, which is of course rdch $2,$ch24 ! -- Updated to only do the setjmp goo around the spu access, and not around prdump because it does its own (via mread). Also the num variable is now common between sf and sd, so you don't have to keep typing the spu number in if you're repeating commands on the same spu. Signed-off-by:

My patch to add spu helpers to xmon (a8984970) introduced a few sparse warnings, because I was dereferencing an __iomem pointer. I think the best way to handle it is to actually use the appropriate in_beXX functions. Need to rejigger the DUMP macro a little to accomodate that. Signed-off-by:

With soft-disabled interrupts in power_save, we can still get external exceptions on Cell, even if we are in pause(0) a.k.a. sleep state. When the CPU really wakes up through the 0x100 (system reset) vector, while we have already started processing the 0x500 (external) exception, we get a panic in unrecoverable_exception() because of the lost state. This occurred in Systemsim for Cell, but as far as I can see, it can theoretically occur on any machine that uses the system reset exception to get out of sleep state. Signed-off-by:

This patch adds SPU elf notes to the coredump. It creates a separate note for each of /regs, /fpcr, /lslr, /decr, /decr_status, /mem, /signal1, /signal1_type, /signal2, /signal2_type, /event_mask, /event_status, /mbox_info, /ibox_info, /wbox_info, /dma_info, /proxydma_info, /object-id. A new macro, ARCH_HAVE_EXTRA_NOTES, was created for architectures to specify they have extra elf core notes. A new macro, ELF_CORE_EXTRA_NOTES_SIZE, was created so the size of the additional notes could be calculated and added to the notes phdr entry. A new macro, ELF_CORE_WRITE_EXTRA_NOTES, was created so the new notes would be written after the existing notes. The SPU coredump code resides in spufs. Stub functions are provided in the kernel which are hooked into the spufs code which does the actual work via register_arch_coredump_calls(). A new set of __spufs_<file>_read/get() functions was provided to allow the coredump code to read from the spufs files without having to lock the SPU context for each file read from.
