PCI: Generate uppercase hex for modalias var in uevent

2015-06-19T03:40:11+00:00

commit 145b3fe579db66fbe999a2bc3fd5b63dffe9636d upstream.

Some implementations of modprobe fail to load the driver for a PCI device
automatically because the "interface" part of the modalias from the kernel
is lowercase, and the modalias from file2alias is uppercase.

The "interface" is the low-order byte of the Class Code, defined in PCI
r3.0, Appendix D.  Most interface types defined in the spec do not use
alpha characters, so they won't be affected.  For example, 00h, 01h, 10h,
20h, etc. are unaffected.

Print the "interface" byte of the Class Code in uppercase hex, as we
already do for the Vendor ID, Device ID, Class, etc.

Commit 89ec3dcf17fd ("PCI: Generate uppercase hex for modalias interface
class") fixed only half of the problem.  Some udev implementations rely on
the uevent file and not the modalias file.

Driver core: change add_uevent_var to use a struct

2007-10-12T21:51:01+00:00

This changes the uevent buffer functions to use a struct instead of a
long list of parameters. It does no longer require the caller to do the
proper buffer termination and size accounting, which is currently wrong
in some places. It fixes a known bug where parts of the uevent
environment are overwritten because of wrong index calculations.

Many thanks to Mathieu Desnoyers for finding bugs and improving the
error handling.

[PATCH] driver core: replace "hotplug" by "uevent"

2006-01-05T00:18:08+00:00

Leave the overloaded "hotplug" word to susbsystems which are handling
real devices. The driver core does not "plug" anything, it just exports
the state to userspace and generates events.

[PATCH] PCI: move pci core to use add_hotplug_env_var()

2005-09-09T18:24:19+00:00

This fixes a bug in the environment variables for all PCI device hotplug calls.

Thanks to Kay Sievers for pointing out the problem.

[PATCH] PCI: Remove newline from pci MODALIAS variable

2005-07-01T20:35:51+00:00

the pci core sends out a hotplug event variable MODALIAS with a trailing
newline. This is inconsistent with all other event variables and breaks
some hotplug tools. This patch removes the said newline.

If my CPCI hotplug update patch is applied, then there are no longer any

removed.

Linux-2.6.12-rc2

2005-04-16T22:20:36+00:00

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!
