* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We already did that a long time ago for pnp_system_init, but pnpacpi_init and pnpbios_init remained as subsys_initcalls, and get linked into the kernel before the arch-specific routines that finalize the PCI resources (pci_subsys_init). This means that the PnP routines would either register their resources before the PCI layer could, or would be unable to check whether a PCI resource had already been registered. Both are problematic. I wanted to do this before 2.6.27, but every time we change something like this, something breaks. That said, _every_ single time we trust some firmware (like PnP tables) more than we trust the hardware itself (like PCI probing), the problems have been worse.

* PNP: convert resource options to single linked listBjorn Helgaas2008-07-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ISAPNP, PNPBIOS, and ACPI describe the "possible resource settings" of a device, i.e., the possibilities an OS bus driver has when it assigns I/O port, MMIO, and other resources to the device. PNP used to maintain this "possible resource setting" information in one independent option structure and a list of dependent option structures for each device. Each of these option structures had lists of I/O, memory, IRQ, and DMA resources, for example: dev independent options ind-io0 -> ind-io1 ... ind-mem0 -> ind-mem1 ... ... dependent option set 0 dep0-io0 -> dep0-io1 ... dep0-mem0 -> dep0-mem1 ... ... dependent option set 1 dep1-io0 -> dep1-io1 ... dep1-mem0 -> dep1-mem1 ... ... ... This data structure was designed for ISAPNP, where the OS configures device resource settings by writing directly to configuration registers. The OS can write the registers in arbitrary order much like it writes PCI BARs. However, for PNPBIOS and ACPI devices, the OS uses firmware interfaces that perform device configuration, and it is important to pass the desired settings to those interfaces in the correct order. The OS learns the correct order by using firmware interfaces that return the "current resource settings" and "possible resource settings," but the option structures above doesn't store the ordering information. This patch replaces the independent and dependent lists with a single list of options. For example, a device might have possible resource settings like this: dev options ind-io0 -> dep0-io0 -> dep1->io0 -> ind-io1 ... All the possible settings are in the same list, in the order they come from the firmware "possible resource settings" list. Each entry is tagged with an independent/dependent flag. Dependent entries also have a "set number" and an optional priority value. All dependent entries must be assigned from the same set. For example, the OS can use all the entries from dependent set 0, or all the entries from dependent set 1, but it cannot mix entries from set 0 with entries from set 1. Prior to this patch PNP didn't keep track of the order of this list, and it assigned all independent options first, then all dependent ones. Using the example above, that resulted in a "desired configuration" list like this: ind->io0 -> ind->io1 -> depN-io0 ... instead of the list the firmware expects, which looks like this: ind->io0 -> depN-io0 -> ind-io1 ...

* PNP: replace pnp_resource_table with dynamically allocated resourcesBjorn Helgaas2008-07-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PNP used to have a fixed-size pnp_resource_table for tracking the resources used by a device. This table often overflowed, so we've had to increase the table size, which wastes memory because most devices have very few resources. This patch replaces the table with a linked list of resources where the entries are allocated on demand. This removes messages like these: pnpacpi: exceeded the max number of IO resources 00:01: too many I/O port resources References: http://bugzilla.kernel.org/show_bug.cgi?id=9535 http://bugzilla.kernel.org/show_bug.cgi?id=9740 http://lkml.org/lkml/2007/11/30/110 This patch also changes the way PNP uses the IORESOURCE_UNSET, IORESOURCE_AUTO, and IORESOURCE_DISABLED flags. Prior to this patch, the pnp_resource_table entries used the flags like this: IORESOURCE_UNSET This table entry is unused and available for use. When this flag is set, we shouldn't look at anything else in the resource structure. This flag is set when a resource table entry is initialized. IORESOURCE_AUTO This resource was assigned automatically by pnp_assign_{io,mem,etc}(). This flag is set when a resource table entry is initialized and cleared whenever we discover a resource setting by reading an ISAPNP config register, parsing a PNPBIOS resource data stream, parsing an ACPI _CRS list, or interpreting a sysfs "set" command. Resources marked IORESOURCE_AUTO are reinitialized and marked as IORESOURCE_UNSET by pnp_clean_resource_table() in these cases: - before we attempt to assign resources automatically, - if we fail to assign resources automatically, - after disabling a device IORESOURCE_DISABLED Set by pnp_assign_{io,mem,etc}() when automatic assignment fails. Also set by PNPBIOS and PNPACPI for: - invalid IRQs or GSI registration failures - invalid DMA channels - I/O ports above 0x10000 - mem ranges with negative length After this patch, there is no pnp_resource_table, and the resource list entries use the flags like this: IORESOURCE_UNSET This flag is no longer used in PNP. Instead of keeping IORESOURCE_UNSET entries in the resource list, we remove entries from the list and free them. IORESOURCE_AUTO No change in meaning: it still means the resource was assigned automatically by pnp_assign_{port,mem,etc}(), but these functions now set the bit explicitly. We still "clean" a device's resource list in the same places, but rather than reinitializing IORESOURCE_AUTO entries, we just remove them from the list. Note that IORESOURCE_AUTO entries are always at the end of the list, so removing them doesn't reorder other list entries. This is because non-IORESOURCE_AUTO entries are added by the ISAPNP, PNPBIOS, or PNPACPI "get resources" methods and by the sysfs "set" command. In each of these cases, we completely free the resource list first. IORESOURCE_DISABLED In addition to the cases where we used to set this flag, ISAPNP now adds an IORESOURCE_DISABLED resource when it reads a configuration register with a "disabled" value.

| * PNP: remove pnp_resource_table from internal get/set interfacesBjorn Helgaas2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When we call protocol->get() and protocol->set() methods, we currently supply pointers to both the pnp_dev and the pnp_resource_table even though the pnp_resource_table should always be the one associated with the pnp_dev. This removes the pnp_resource_table arguments to make it clear that these methods only operate on the specified pnp_dev.

* pnp: declare PNP option parsing functions as __initThomas Renninger2008-02-06
| | | | | | | | | | | | | | | | | | | There are three kind of parse functions provided by PNP acpi/bios: - get current resources - set resources - get possible resources The first two may be needed later at runtime. The possible resource settings should never change dynamically. And even if this would make any sense (I doubt it), the current implementation only parses possible resource settings at early init time: -> declare all the option parsing __init [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: Thomas Renninger <trenn@suse.de> Acked-By: Rene Herman <rene.herman@gmail.com> Cc: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* drivers/firmware: const-ify DMI API and internalsJeff Garzik2007-10-09
| | | | | | | | | | | | | | | | | | | | | | | Three main sets of changes: 1) dmi_get_system_info() return value should have been marked const, since callers should not be changing that data. 2) const-ify DMI internals, since DMI firmware tables should, whenever possible, be marked const to ensure we never ever write to that data area. 3) const-ify DMI API, to enable marking tables const where possible in low-level drivers. And if we're really lucky, this might enable some additional optimizations on the part of the compiler. The bulk of the changes are #2 and #3, which are interrelated. #1 could have been a separate patch, but it was so small compared to the others, it was easier to roll it into this changeset.
