[PATCH] x86: pci_assign_unassigned_resources() update

2005-09-10T02:42:51+00:00

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 (who had problems with the 4kB CardBus IO size previously). Signed-off-by: Linus Torvalds Signed-off-by: Chris Wright Signed-off-by: Greg Kroah-Hartman

[PATCH] Fix PCI ROM mapping

2005-09-10T02:42:50+00:00

This fixes a problem with pci_map_rom() which doesn't properly update the ROM BAR value with the address thas allocated for it by the PCI code. This problem, among other, breaks boot on Mac laptops. It'ss a new version based on Linus latest one with better error checking.

Ignore disabled ROM resources at setup

2005-08-26T17:49:22+00:00

Writing even a disabled value seems to mess up some matrox graphics cards. It may be a card-related issue, but we may also be writing reserved low bits in the result. This was a fall-out of switching x86 over to the generic PCI resource allocation code, and needs more debugging. In particular, the old x86 code defaulted to not doing any resource allocations at all for ROM resources. In the meantime, this has been reported to make X happier by Helge Hafting .

Only pre-allocate 256 bytes of cardbio IO range

2005-08-26T17:40:10+00:00

It may seem small, but most cards need much less, if any, and this not only makes the code adhere to the comment, it seems to fix a boot-time lockup on a ThinkPad 380XD laptop reported by Tero Roponen Signed-off-by: Linus Torvalds

[PATCH] PCI: 6700/6702PXH quirk

2005-08-17T04:06:24+00:00

On the 6700/6702 PXH part, a MSI may get corrupted if an ACPI hotplug driver and SHPC driver in MSI mode are used together. This patch will prevent MSI from being enabled for the SHPC as part of an early pci quirk, as well as on any pci device which sets the no_msi bit.

Revert "[PATCH] PCI: restore BAR values..."

2005-08-09T01:46:09+00:00

Revert commit fec59a711eef002d4ef9eb8de09dd0a26986eb77, which is breaking sparc64 that doesn't have a working pci_update_resource. We'll re-do this after 2.6.13 when we'll do it all properly.

[PATCH] VIA VT8235 PCI quirk

2005-08-08T18:46:24+00:00

Like many other southbridges from different manufacturers, VIA VT8235 chip has two non-standard BARs for power management and SMBus registers (see the datasheet at http://www.via.com.tw). This new quirk routine fixes boot problem with 2.6.13-rc2/rc6 kernels on Targa Visionary 811 Athlon64 laptop, as reported by Mikael Pettersson .

[PATCH] Fix restore of 64-bit PCI BAR's

2005-08-07T16:50:56+00:00

For 64-bit BAR[i] only pci_dev->resource[i] is valid, ->resource[i+1] slot is unused and contains zeroes in all fields. So when we update a PCI BAR, all we need is just to check that we're going to update a _valid_ resource. Also make sure to write high bits - use "x >> 16 >> 16" (rather than the simpler ">> 32") to avoid warnings on 32-bit architectures where we're not going to have any high bits.
