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.

2008-04-29PNP: add pnp_init_resources(struct pnp_dev *) interfaceBjorn Helgaas
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 more pnp_resource_table argumentsBjorn Helgaas
Stop passing around struct pnp_resource_table pointers. In most cases, the caller doesn't need to know how the resources are stored inside the struct pnp_dev.

2008-04-29PNP: remove pnp_resource_table from internal get/set interfacesBjorn Helgaas
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 pnp_alloc_card()Bjorn Helgaas

2008-04-29ISAPNP: pull pnp_add_card_id() out of isapnp_parse_card_id()Bjorn Helgaas
Split the pnp_add_card_id() part from the PNPID conversion part so we can move the initial add_id() into the pnp_card allocation.

2008-04-29PNP: add pnp_eisa_id_to_string()Bjorn Helgaas
Converting the EISA ID to a string is messy and error-prone, and we might as well use the same code for ISAPNP and PNPBIOS.

2008-03-22ISAPNP: fix limits of logical device register setBjorn Helgaas
PNP_MAX_MEM and PNP_MAX_PORT are mainly used to size tables of PNP device resources. In 2.6.24, we increased their values to accomodate ACPI devices that have many resources: 2.6.23 2.6.24 ------ ------ PNP_MAX_MEM 4 12 PNP_MAX_PORT 8 40 However, ISAPNP also used these constants as the size of parts of the logical device register set. This register set is fixed by hardware, so increasing the constants meant that we were reading and writing unintended parts of the register set. This patch changes ISAPNP to use the correct register set sizes (the same values we used prior to 2.6.24).

2007-07-16isapnp: remove pointless check of 'type' against 0 in isapnp_read_tag()Jesper Juhl
In drivers/pnp/isapnp/core.c::isapnp_read_tag() there is a test of 'type' being == 0 a bit down in the function. That test doesn't make any sense. If 'type' could indeed be NULL, then the test happens way too late as we'd already have tried to dereference the pointer earlier and looking at the callers it also turns out that there is no way type can ever actually be NULL. So the test is completely pointless and should just be removed.

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 Torvalds
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!
