2009-07-03parisc: Fix gcc 4.4 warning in lba_pci.cGrant Grundler1-9/+22
gcc 4.4 warns about: drivers/parisc/lba_pci.c: In function 'lba_pat_resources': drivers/parisc/lba_pci.c:1099: warning: the frame size of 8280 bytes is larger than 4096 bytes The problem is we declare two large structures on the stack. They don't need to be on the stack since they are only used during LBA initialization (which is serialized). Moving to be "static".

2009-07-03parisc: advertise PCI devs after "assign_resources"Grant Grundler1-5/+5
Alex Chiang asked me why PARISC was calling pci_bus_add_devices() and pci_bus_assign_resources() in the opposite order from everyone else. No reason and I couldn't see any data dependency. Patch below applies cleanly to 2.6.30-rc2. Later, I suspected the code worked only because no drivers would be loaded/ready until much later in the system initialization sequence. Tested "LBA" code on J6000 (32-bit) and A500 (64-bit SMP) with 2.6.30-rc2. Not tested with any Dino controllers. Not tested with PCI-PCI Bridge (TBD).

2009-03-13parisc: fix wrong assumption about bus->selfGrant Grundler1-2/+2
Kenji Kaneshige <kaneshige.kenji@jp.fujitsu.com> posted a patch series to linux-pci to fix a wrong assumption about pci_bus->self==NULL for all PCI host bus controllers. While PARISC platforms to not behave this way, I prefer to have the code consistent across architectures. The following patch replaces pci_bus->self with pci_bus->parent when used as a test to check for "root bus controller".

2007-12-06[PARISC] lba_pci: pci_claim_resources disabled expansion romsKyle McMartin1-3/+7
radeonfb was HPMC-ing my C8000 by trying to map its expansion rom from IO_VIEW, instead of PA_VIEW. Fix seems to be to ensure that its disabled ROM is properly inserted into the resource tree. FIXME: this will result in a whinging printk for cards which share expansion ROMS, such as a quad tulip. Thankfully, it isn't harmful. Signed-off-by: Kyle McMartin <kyle@mcmartin.ca>
2007-10-18[PARISC] Fix infinite loop in /proc/iomemMatthew Wilcox1-44/+7
pcibios_link_hba_resources() could corrupt the resource tree by inserting resources in the wrong place. Fix this by calling pci_claim_resource() for PCI-PCI bridges. Delete pcibios_link_hba_resources as we shouldn't need it any more. Also get rid of lba_claim_dev_resources() and just call pci_claim_resource() directly.

2006-12-08[PARISC] Fix PCI bus numbering in the presence of Cardbus bridgesMatthew Wilcox1-13/+19
Firmware ignores Cardbus bridges, so when Linux assigns bus numbers, it must override firmware's notion of what the busses are numbered. This is not sufficient to support the Cardbus bridge as there is also no interrupt routing table entry for them.

2005-06-28[PATCH] acpi bridge hotadd: ACPI based root bridge hot-addRajesh Shah1-0/+2
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.

2005-04-17Linux-2.6.12-rc2Linus Torvalds1-0/+1649
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!
