* [PATCH] arch/386/pci: remap_pfn_range -> io_remap_pfn_rangeMichael S. Tsirkin2005-09-081-3/+3
| | | | | | | | Convert i386/pci to use io_remap_pfn_range instead of remap_pfn_range. This is good for Xen which reuses i386/pci/i386.c for domain 0 code. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| * [PATCH] x86: pci_assign_unassigned_resources() updateIvan Kokshaysky2005-08-302-34/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I had some time to think about PCI assign issues in 2.6.13-rc series. The major problem here is that we call pci_assign_unassigned_resources() way too early - at subsys_initcall level. Therefore we give no chances to ACPI and PnP routines (called at fs_initcall level) to reserve their respective resources properly, as the comments in drivers/pnp/system.c and drivers/acpi/motherboard.c suggest: /** * Reserve motherboard resources after PCI claim BARs, * but before PCI assign resources for uninitialized PCI devices */ So I moved the pci_assign_unassigned_resources() call to pcibios_assign_resources() (fs_initcall), which should hopefully fix a lot of problems and make PCIBIOS_MIN_IO tweaks unnecessary. Other changes: - remove resource assignment code from pcibios_assign_resources(), since it duplicates pci_assign_unassigned_resources() functionality and actually does nothing in 2.6.13; - modify ROM assignment code as per Ben's suggestion: try to use firmware settings by default (if PCI_ASSIGN_ROMS is not set); - set CARDBUS_IO_SIZE back to 4K as it's a wonderful stress test for various setups. Confirmed by Tero Roponen <teanropo@cc.jyu.fi> (who had problems with the 4kB CardBus IO size previously). Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| * [PATCH] Fix incorrect Asus k7m irq router detectionGiancarlo Formicuccia2005-07-281-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch: http://marc.theaimsgroup.com/?l=bk-commits-head&m=111955644929114&w=2 uncovered a k7m bios bug, where the VT82C686A router is reported as being "586-compatible". The two chips have different pirq mapping, so this leads to "irq routing conflict" on many pci devices. The suggested fix was discussed with Aleksey Gorelov, who helped me to identify the problem as a probable bios bug.

* | [PATCH] PCI: pci_assign_unassigned_resources() on x86Ivan Kokshaysky2005-07-012-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Add sanity check for io[port,mem]_resource in setup-bus.c. These resources look like "free" as they have no parents, but obviously we must not touch them. - In i386.c:pci_allocate_bus_resources(), if a bridge resource cannot be allocated for some reason, then clear its flags. This prevents any child allocations in this range, so the setup-bus code will work with a clean resource sub-tree. - i386.c:pcibios_enable_resources() doesn't enable bridges, as it checks only resources 0-5, which looks like a clear bug to me. I suspect it might break hotplug as well in some cases. From: Ivan Kokshaysky <ink@jurassic.park.msu.ru> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* | [PATCH] PCI: use the MCFG table to properly access pci devices (i386)Greg Kroah-Hartman2005-06-271-4/+25
| | | | | | | | | | | | | | | | | | | | | | | | Now that we have access to the whole MCFG table, let's properly use it for all pci device accesses (as that's what it is there for, some boxes don't put all the busses into one entry.) If, for some reason, the table is incorrect, we fallback to the "old style" of mmconfig accesses, namely, we just assume the first entry in the table is the one for us, and blindly use it.

* | [PATCH] PCI: add proper MCFG table parsing to ACPI core.Greg Kroah-Hartman2005-06-271-5/+7
| | | | | | | | | | | | | | | | | | | | This patch is the first step in properly handling the MCFG PCI table. It defines the structures properly, and saves off the table so that the pci mmconfig code can access it. It moves the parsing of the table a little later in the boot process, but still before the information is needed. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* | [PATCH] acpi bridge hotadd: ACPI based root bridge hot-addRajesh Shah2005-06-273-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When you hot-plug a (root) bridge hierarchy, it may have p2p bridges and devices attached to it that have not been configured by firmware. In this case, we need to configure the devices before starting them. This patch separates device start from device scan so that we can introduce the configuration step in the middle. I kept the existing semantics for pci_scan_bus() since there are a huge number of callers to that function. Also, I have no way of testing the changes I made to the parisc files, so this needs review by those folks. Sorry for the massive cross-post, this touches files in many different places.

* | [PATCH] PCI Allow OutOfRange PIRQ table addressjayalk@intworks.biz2005-06-273-15/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I updated this to remove unnecessary variable initialization, make check_routing be inline only and not __init, switch to strtoul, and formatting fixes as per Randy Dunlap's recommendations. I updated this to change pirq_table_addr to a long, and to add a warning msg if the PIRQ table wasn't found at the specified address, as per thread with Matthew Wilcox. In our hardware situation, the BIOS is unable to store or generate it's PIRQ table in the F0000h-100000h standard range. This patch adds a pci kernel parameter, pirqaddr to allow the bootloader (or BIOS based loader) to inform the kernel where the PIRQ table got stored. A beneficial side-effect is that, if one's BIOS uses a static address each time for it's PIRQ table, then pirqaddr can be used to avoid the $pirq search through that address block each time at boot for normal PIRQ BIOSes.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-1613-0/+3393
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!
