2011-03-22pnp: only assign IORESOURCE_DMA if CONFIG_ISA_DMA_API is enabledDavid Rientjes
IORESOURCE_DMA cannot be assigned without utilizing the interface provided by CONFIG_ISA_DMA_API, specifically request_dma() and free_dma(). Thus, there's a strict dependency on the config option and limits IORESOURCE_DMA only to architectures that support ISA-style DMA. ia64 is not one of those architectures, so pnp_check_dma() no longer needs to be special-cased for that architecture. pnp_assign_resources() will now return -EINVAL if IORESOURCE_DMA is attempted on such a kernel.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
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.

2008-07-16PNP: convert resource options to single linked listBjorn Helgaas
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 ...

2008-07-16PNP: support optional IRQ resourcesBjorn Helgaas
This patch adds an IORESOURCE_IRQ_OPTIONAL flag for use when assigning resources to a device. If the flag is set and we are unable to assign an IRQ to the device, we can leave the IRQ disabled but allow the overall resource allocation to succeed. Some devices request an IRQ, but can run without an IRQ (possibly with degraded performance). This flag lets us run the device without the IRQ instead of just leaving the device disabled. This is a reimplementation of this previous change by Rene Herman <rene.herman@gmail.com>: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=3b73a223661ed137c5d3d2635f954382e94f5a43 I reimplemented this for two reasons: - to prepare for converting all resource options into a single linked list, as opposed to the per-resource-type lists we have now, and - to preserve the order and number of resource options. In PNPBIOS and ACPI, we configure a device by giving firmware a list of resource assignments. It is important that this list has exactly the same number of resources, in the same order, as the "template" list we got from the firmware in the first place. The problem of a sound card MPU401 being left disabled for want of an IRQ was reported by Uwe Bugla <uwe.bugla@gmx.de>.

2008-07-16PNP: replace pnp_resource_table with dynamically allocated resourcesBjorn Helgaas
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.

2008-07-16PNP: remove pnp_resource.indexBjorn Helgaas
We used pnp_resource.index to keep track of which ISAPNP configuration register a resource should be written to. We needed this only to handle the case where a register is disabled but a subsequent register in the same set is enabled. Rather than explicitly maintaining the pnp_resource.index, this patch adds a resource every time we read an ISAPNP configuration register and marks the resource as IORESOURCE_DISABLED when appropriate. This makes the position in the pnp_resource_table always correspond to the config register index.

2008-04-29PNP: add pnp_resource index for ISAPNPBjorn Helgaas
Save the ISAPNP config register index in the struct pnp_resource. We need this because it is important to write ISAPNP configuration back to the same registers we read it from. For example, if we read valid regions from memory descriptors 0, 1, and 3, we'd better write them back to the same registers, without compressing them to descriptors 0, 1, and 2. This was previously guaranteed by using the index into the pnp_resource_table array as the ISAPNP config register index. However, I am removing those fixed-size arrays, so we need to save the ISAPNP register index elsewhere.

2005-11-07[PATCH] drivers/pnp/: cleanupsAdrian Bunk
This patch contains the following possible cleanups: - make needlessly global code static - #if 0 the following unused global function: - core.c: pnp_remove_device - #if 0 the following unneeded EXPORT_SYMBOL's: - card.c: pnp_add_card - card.c: pnp_remove_card - card.c: pnp_add_card_device - card.c: pnp_remove_card_device - card.c: pnp_add_card_id - core.c: pnp_register_protocol - core.c: pnp_unregister_protocol - core.c: pnp_add_device - core.c: pnp_remove_device - pnpacpi/core.c: pnpacpi_protocol - driver.c: pnp_add_id - isapnp/core.c: isapnp_read_byte - manager.c: pnp_auto_config_dev - resource.c: pnp_register_dependent_option - resource.c: pnp_register_independent_option - resource.c: pnp_register_irq_resource - resource.c: pnp_register_dma_resource - resource.c: pnp_register_port_resource - resource.c: pnp_register_mem_resource Note that this patch #if 0's exactly one functions and removes no functions. Most it does is the #if 0 of EXPORT_SYMBOL's, so if any modular code will use any of them, re-adding will be trivial. Modular ISAPnP might be interesting in some cases, but this is more legacy code. If someone would work on it to sort all the issues out (starting with the point that most users of __ISAPNP__ will have to be fixed) re-enabling the required EXPORT_SYMBOL's won't be hard for him.

2005-10-30[PATCH] fix missing includesTim Schmielau
I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

2005-09-07[PATCH] PNP: make pnp_dbg conditional directly on CONFIG_PNP_DEBUGBjorn Helgaas
Seems pointless to require .c files to test CONFIG_PNP_DEBUG and conditionally define DEBUG before including <linux/pnp.h>. Just test CONFIG_PNP_DEBUG directly in pnp.h.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
