2008-04-29PNP: convert resource accessors to use pnp_get_resource(), not ↵Bjorn Helgaas1-40/+105

2008-04-29PNP: add pnp_get_resource() interfaceBjorn Helgaas1-0/+1
This adds a pnp_get_resource() that works the same way as platform_get_resource(). This will enable us to consolidate many pnp_resource_table references in one place, which will make it easier to make the table dynamic.

2008-04-29PNP: remove unused interfaces using pnp_resource_tableBjorn Helgaas1-8/+0
Rene Herman <[email protected]> recently removed the only in-tree driver uses of: pnp_init_resource_table() pnp_manual_config_dev() pnp_resource_change() in this change: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=109c53f840e551d6e99ecfd8b0131a968332c89f These are no longer used in the PNP core either, so we can just remove them completely. It's possible that there are out-of-tree drivers that use these interfaces. They should be changed to either (1) use PNP quirks to work around broken hardware or firmware, or (2) use the sysfs interfaces to control resource usage from userspace.

2008-04-29PNP: add pnp_init_resources(struct pnp_dev *) interfaceBjorn Helgaas1-0/+2
Add pnp_init_resources(struct pnp_dev *) to replace pnp_init_resource_table(), which takes a pointer to the pnp_resource_table itself. Passing only the pnp_dev * reduces the possibility for error in the caller and removes the pnp_resource_table implementation detail from the interface. Even though pnp_init_resource_table() is exported, I did not export pnp_init_resources() because it is used only by the PNP core.

2008-04-29PNP: remove pnp_resource_table from internal get/set interfacesBjorn Helgaas1-2/+2
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.

2008-04-29PNP: add debug output to option registrationBjorn Helgaas1-8/+11
Add debug output to resource option registration functions (enabled by CONFIG_PNP_DEBUG). This uses dev_printk, so I had to add pnp_dev arguments at the same time. Signed-off-by: Bjorn Helgaas <[email protected]> Acked-By: Rene Herman <[email protected]> Signed-off-by: Len Brown <[email protected]>

2008-04-11pnp: increase number of devices supported per protocolBjorn Helgaas1-1/+1
Increase the PNP "number of devices" limit. We currently use an unsigned char, which limits us to 256 devices per protocol. This patch changes that to an unsigned int. Not all backends can take advantage of this: we limit ISAPNP to 10 devices in isapnp_cfg_begin(), and PNPBIOS is limited to 256 devices because the BIOS interfaces use a one-byte device node number. But there is no limit on the number of PNPACPI devices we may have. Large HP Integrity machines have more than 256, which causes the current "unsigned char number" to wrap around. This causes errors like this: pnp: PnP ACPI init kobject_add failed for 00:00 with -EEXIST, don't try to register things with the same name in the same directory.

It should not have any adverse effect on ISAPNP or PNPBIOS because their limits are still enforced in the backends.

2007-12-27increase PNP_MAX_PORT to 40 from 24Len Brown1-1/+1
a7839e960675b549f06209d18283d5cee2ce9261 (PNP: increase the maximum number of resources) increased PNP_MAX_PORT to 24 from 8. It also added a test and a complaint when a machine exceeded the limit, causing: pnpacpi: exceeded the max number of IO resources: 24 http://bugzilla.kernel.org/show_bug.cgi?id=9535 We should have been squawking about this all along, as this is a potentially serious issue. For now, simply burn some dynamic bytes and increase the limit by another 16 to 40. There is no guarantee that this will satisfy every system on Earth. It probably will not, but it should be an improvement. In the future, PNPACPI should allocate resource structures as needed, rather than max-sized arrays. Signed-off-by: Len Brown <[email protected]>
2007-11-29PNP: increase the maximum number of resourcesZhao Yakui1-2/+2
On some systems the number of resources(IO,MEM) returnedy by PNP device is greater than the PNP constant, for example motherboard devices. It brings that some resources can't be reserved and resource confilicts. This will cause PCI resources are assigned wrongly in some systems, and cause hang. This is a regression since we deleted ACPI motherboard driver and use PNP system driver.

2007-05-08PNP: notice whether we have PNP devices (PNPBIOS or PNPACPI)Bjorn Helgaas1-0/+2
This series converts i386 and x86_64 legacy serial ports to be platform devices and prevents probing for them if we have PNP. This prevents double discovery, where a device was found both by the legacy probe and by 8250_pnp. This also prevents the serial driver from claiming IRDA devices (unless they have a UART PNP ID). The serial legacy probe sometimes assumed the wrong IRQ, so the user had to use "setserial" to fix it. Removing the need for setserial to make IRDA devices work seems good, but it does break some things. In particular, you may need to keep setserial from poking legacy UART stuff back in by doing something like "dpkg-reconfigure setserial" with the "kernel" option. Otherwise, the setserial-discovered "UART" will claim resources and prevent the IRDA driver from loading. This patch: If we can discover devices using PNP, we can skip some legacy probes. This flag ("pnp_platform_devices") indicates that PNPBIOS or PNPACPI is enabled and should tell us about builtin devices.

2007-05-08init dma masks in pnp_devDavid Brownell1-0/+1
PNP now initializes device dma masks, which prevents oopses when generic dma calls are made using pnp device nodes. This assumes PNP only uses ISA DMA, with 24 bit addresses; and that it's safe to init those masks for all devices (rather than finding out which devices have been assigned DMA channels, and handling only those).

2007-02-11[PATCH] PNP: export pnp_bus_typeDavid Brownell1-0/+2
The PNP framework doesn't export "pnp_bus_type", which is an unfortunate exception to the policy followed by pretty much every other bus. I noticed this when I had to find a device in order to provide its platform_data. Note that per advice from Arjan, the "export" scope has been been minimized to avoid the hundred-plus bytes needed to support access from modules. In this case, the symbol is only needed by statically linked kernel code that lives outside the drivers/pnp directory.

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.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+454
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!
