2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.hTejun Heo1-1/+0
percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

2009-03-11powerpc/kconfig: Kill PPC_MULTIPLATFORMBenjamin Herrenschmidt1-1/+1
CONFIG_PPC_MULTIPLATFORM is a remain of the pre-powerpc days and isn't really meaningful anymore. It was basically equivalent to PPC64 || 6xx. This removes it along with the following changes: - 32-bit platforms that relied on PPC32 && PPC_MULTIPLATFORM now rely on 6xx which is what they want anyway. - A new symbol, PPC_BOOK3S, is defined that represent compliance with the "Server" variant of the architecture. This is set when either 6xx or PPC64 is set and open the door for future BOOK3E 64-bit. - 64-bit platforms that relied on PPC64 && PPC_MULTIPLATFORM now use PPC64 && PPC_BOOK3S - A separate and selectable CONFIG_PPC_OF_BOOT_TRAMPOLINE option is now used to control the use of prom_init.c Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2008-03-26[POWERPC] maple: Use platform name in define_machine()Nathan Lynch1-1/+1
Prevailing practice for define_machine() in powerpc is to use the platform name when the platform has only one define_machine() statement, but maple uses "maple_md". This caused me some head-scratching when writing some new code that uses machine_is(maple). Use "maple" instead of "maple_md". There should not be any behavioral change -- fixup_maple_ide() calls machine_is(maple) but the body of the function is ifdef'd out.

2007-08-17[POWERPC] Remove gratuitous reads from maple PCI config space methodsNathan Lynch1-9/+0
The maple PCI configuration space write methods read the written location immediately after the write is performed, presumably in order to flush the write. However, configuration space writes are not allowed to be posted, making these reads gratuitous. Furthermore, this behavior potentially causes us to violate the PCI PM spec when changing between e.g. D0 and D3 states, because a delay of up to 10ms may be required before the OS accesses configuration space after the write which initiates the transition. It definitely causes a system hang for me with a Broadcom 5721 PCIE network adapter, which is fixed by this change. Therefore this removes the gratuitous reads from u3_agp_write_config, u3_ht_write_config, and u4_pcie_write_config.

2007-06-14[POWERPC] Rewrite IO allocation & mapping on powerpc64Benjamin Herrenschmidt1-35/+0
This rewrites pretty much from scratch the handling of MMIO and PIO space allocations on powerpc64. The main goals are: - Get rid of imalloc and use more common code where possible - Simplify the current mess so that PIO space is allocated and mapped in a single place for PCI bridges - Handle allocation constraints of PIO for all bridges including hot plugged ones within the 2GB space reserved for IO ports, so that devices on hotplugged busses will now work with drivers that assume IO ports fit in an int. - Cleanup and separate tracking of the ISA space in the reserved low 64K of IO space. No ISA -> Nothing mapped there. I booted a cell blade with IDE on PIO and MMIO and a dual G5 so far, that's it :-) With this patch, all allocations are done using the code in mm/vmalloc.c, though we use the low level __get_vm_area with explicit start/stop constraints in order to manage separate areas for vmalloc/vmap, ioremap, and PCI IOs. This greatly simplifies a lot of things, as you can see in the diffstat of that patch :-) A new pair of functions pcibios_map/unmap_io_space() now replace all of the previous code that used to manipulate PCI IOs space. The allocation is done at mapping time, which is now called from scan_phb's, just before the devices are probed (instead of after, which is by itself a bug fix). The only other caller is the PCI hotplug code for hot adding PCI-PCI bridges (slots). imalloc is gone, as is the "sub-allocation" thing, but I do beleive that hotplug should still work in the sense that the space allocation is always done by the PHB, but if you unmap a child bus of this PHB (which seems to be possible), then the code should properly tear down all the HPTE mappings for that area of the PHB allocated IO space. I now always reserve the first 64K of IO space for the bridge with the ISA bus on it. I have moved the code for tracking ISA in a separate file which should also make it smarter if we ever are capable of hot unplugging or re-plugging an ISA bridge. This should have a side effect on platforms like powermac where VGA IOs will no longer work. This is done on purpose though as they would have worked semi-randomly before. The idea at this point is to isolate drivers that might need to access those and fix them by providing a proper function to obtain an offset to the legacy IOs of a given bus.

This patch reworks the way IRQs are fixed up on PCI for arch powerpc. It makes pci_read_irq_line() called by default in the PCI code for devices that are probed, and add an optional per-device fixup in ppc_md for platforms that really need to correct what they obtain from pci_read_irq_line(). It also removes ppc_md.irq_bus_setup which was only used by pSeries and should not be needed anymore. I've also removed the pSeries s7a workaround as it can't work with the current interrupt code anyway. I'm trying to get one of these machines working so I can test a proper fix for that problem. I also haven't updated the old-style fixup code from 85xx_cds.c because it's actually buggy :) It assigns pci_dev->irq hard coded numbers which is no good with the new IRQ mapping code. It should at least use irq_create_mapping(NULL, hard_coded_number); and possibly also set_irq_type() to set them as level low.

When there is a PCI-X mode 2 capable device behind the HT<->PCI-X bridge, the pci core decides that the device has the extended 4K config space, even though the bus is not operating in mode 2. This is because the u3_ht pci ops silently accept offsets greater than 255 but use only the 8 least significant bits, which means reading at offset 0x100 gets the data at offset 0x0, and causes confusion for lspci.

2006-07-03[POWERPC] Add new interrupt mapping core and change platforms to use itBenjamin Herrenschmidt2-35/+70
This adds the new irq remapper core and removes the old one. Because there are some fundamental conflicts with the old code, like the value of NO_IRQ which I'm now setting to 0 (as per discussions with Linus), etc..., this commit also changes the relevant platform and driver code over to use the new remapper (so as not to cause difficulties later in bisecting). This patch removes the old pre-parsing of the open firmware interrupt tree along with all the bogus assumptions it made to try to renumber interrupts according to the platform. This is all to be handled by the new code now. For the pSeries XICS interrupt controller, a single remapper host is created for the whole machine regardless of how many interrupt presentation and source controllers are found, and it's set to match any device node that isn't a 8259. That works fine on pSeries and avoids having to deal with some of the complexities of split source controllers vs. presentation controllers in the pSeries device trees. The powerpc i8259 PIC driver now always requests the legacy interrupt range. It also has the feature of being able to match any device node (including NULL) if passed no device node as an input. That will help porting over platforms with broken device-trees like Pegasos who don't have a proper interrupt tree.
