* powerpc/8xxx: remove 85xx/86xx restrictions from fsl_guts.hTimur Tabi2012-03-295-26/+10Star
| | | | | | | | | | | | | | Remove the check for CONFIG_PPC_85xx and CONFIG_PPC_86xx from fsl_guts.h. The check was originally intended to allow the same header file to be used on 85xx and 86xx systems, even though the Global Utilities register could be different. It turns out that they're not actually different, and so the check is not necessary. In addition, neither macro is defined for 64-bit e5500 kernels, so that causes a build break.

* powerpc/perf: Fix instruction address sampling on 970 and Power4Benjamin Herrenschmidt2012-03-284-5/+45
| | | | | | | | | | | | | | 970 and Power4 don't support "continuous sampling" which means that when we aren't in marked instruction sampling mode (marked events), SIAR isn't updated with the last instruction sampled before the perf interrupt. On those processors, we must thus use the exception SRR0 value as the sampled instruction pointer. Those processors also don't support the SIPR and SIHV bits in MMCRA which means we need some kind of heuristic to decide if SIAR values represent kernel or user addresses.

* powerpc/pseries: Parse and handle EPOW interruptsAnton Blanchard2012-03-281-17/+116
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We have code to take environmental and power warning (EPOW) interrupts but it simply prints a terse error message: EPOW <0x6240040000000b8 0x0 0x0> which tells us nothing about what happened. Even worse, if we don't correctly respond to the interrupt we may get terminated by firmware. Add code to printk some useful information when we get EPOW events. We want to make it clear that we have an error, that it was reported by firmware and that the RTAS error log will have more detailed information. eg: Ambient temperature too high reported by firmware. Check RTAS error log for details Depending on the error encountered, we now issue an immediate or an orderly power down. Move initialization of the EPOW interrupt earlier in boot since we want to respond to them as early as possible.

* powerpc/eeh: Retrieve PHB from global listGavin Shan2012-03-281-14/+5Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the existing PHBs are retrieved from the FDT (Flat Device Tree) based on the name of FDT node. Specificly, those FDT nodes whose names have prefix "pci" are regarded as PHBs. That's inappropriate because some PCI bridges possibilly have names leading with "pci". It caused EEH is enabled on same PCI devices for towice. The patch fixes the above issue. Besides, the PHBs are expected to be figured out from FDT before enable EEH on them. Therefore, it's resonable to retrieve the PHBs from the global linked list traced by variable "hose_list" insteading poking them from FDT. For the EEH implementation on pSeries platform, RTAS is critical because all low-level functions are implemented based on RTAS. Therefore, we should make sure "/rtas" OF node is available and ready before to enable EEH core. However, it actually introduced duplicate since the previous pSeries platform dependent initialization function already do the check. Besides, we want to make eeh core platform independent, so RTAS related staff should be removed there. The patch removes the duplicate check on "/rtas" OF node for eeh core.

| | | | | | | | | | | | Originally, the PCI sensitive OF node is tracing the eeh device through struct device_node->edev. However, it was regarded as bad idea. The patch removes struct device_node->edev and uses PCI_DN to trace the corresponding eeh device according to BenH's comments.

Due to historical reasons, we have some BUG code in bug.h and some in kernel.h -- i.e. the support for BUILD_BUG in linux/kernel.h predates the addition of linux/bug.h, but old code in kernel.h wasn't moved to bug.h at that time. As a band-aid, kernel.h was including <asm/bug.h> to pseudo link them. This has caused confusion[1] and general yuck/WTF[2] reactions. Here is an example that violates the principle of least surprise: CC lib/string.o lib/string.c: In function 'strlcat': lib/string.c:225:2: error: implicit declaration of function 'BUILD_BUG_ON' make[2]: *** [lib/string.o] Error 1 $ $ grep linux/bug.h lib/string.c #include <linux/bug.h> $ We've included <linux/bug.h> for the BUG infrastructure and yet we still get a compile fail! [We've not kernel.h for BUILD_BUG_ON.] Ugh - very confusing for someone who is new to kernel development. With the above in mind, the goals of this changeset are: 1) find and fix any include/*.h files that were relying on the implicit presence of BUG code. 2) find and fix any C files that were consuming kernel.h and hence relying on implicitly getting some/all BUG code. 3) Move the BUG related code living in kernel.h to <linux/bug.h> 4) remove the asm/bug.h from kernel.h to finally break the chain. During development, the order was more like 3-4, build-test, 1-2. But to ensure that git history for bisect doesn't get needless build failures introduced, the commits have been reorderd to fix the problem areas in advance.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a header file is making use of BUG, BUG_ON, BUILD_BUG_ON, or any other BUG variant in a static inline (i.e. not in a #define) then that header really should be including <linux/bug.h> and not just expecting it to be implicitly present. We can make this change risk-free, since if the files using these headers didn't have exposure to linux/bug.h already, they would have been causing compile failures/warnings.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we already have a debugreg.h header file, move the assoc. get/set functions to it. In addition to it being the logical home for them, it has a secondary advantage. The functions that are moved use BUG(). So we really need to have linux/bug.h in scope. But asm/processor.h is used about 600 times, vs. only about 15 for debugreg.h -- so adding bug.h to the latter reduces the amount of time we'll be processing it during a compile.

We remove it and use a generic approach instead. A new ios_handler is added, the purpose of which e.g. can be to control GPIO pins to a levelshifter. Previously the vdd_handler was also used for making additional changes to the power register bits. This option is superfluous and is therefore removed. Adaptaptions from the old vdd_handler to the new ios_handler is done for mach-ux500 board, which was the only one using the vdd_handler. This patch is based upon a patch from Sebastian Rasmussen.

The RealView EB, when used with the 11MPCore tile, has a number of devices without interrupts, and uses the value -1 to indicate this. Change that value to 0 to conform to the new behaviour.
