2007-07-11PCI: add pci_try_set_mwiRandy Dunlap
As suggested by Andrew, add pci_try_set_mwi(), which does not require return-value checking. - add pci_try_set_mwi() without __must_check - make it return 0 on success, errno if the "try" failed or error - review callers Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-07-11PCI: remove useless pci driver methodDavid Brownell
Remove pointless and never-called enable_wake() hook from pci_driver and from documentation. Evidently this was introduced in the 2.4.6 kernel, but there's no evidence it was ever called; and it was rarely implemented.

2007-05-02PCI: Require vendor and device for new_idJean Delvare
Currently, there is no minimum number of fields required when adding a new device ID to a PCI driver through the new_id sysfs file. It is possible to add a new ID with only the vendor ID set, causing the driver to attempt to attach to all PCI devices from that vendor. This has been reported to happen accidentally: http://lists.lm-sensors.org/pipermail/lm-sensors/2007-March/019366.html It is even possible to not even set the vendor ID field, causing the driver to attempt to attach to _all_ the PCI devices. This sounds dangerous and I fail to see any valid use of this "feature". Thus I suggest that we now require at least the first two fields (vendor ID and device ID) to be set. For what it's worth, this is what the USB subsystem does. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-02-16PCI: pci.txt fix __devexit() usageGrant Grundler
Marin Mitov <mitov@issp.bas.bg> spotted a brainfart where I had failed to update copied text with *_remove and __devexit(). Marin made a good comment in his email to me: | mydriver_probe() is _always_ executed, while mydriver_remove() is not. | See: include/linux/init.h Which says: /* Functions marked as __devexit may be discarded at kernel link time, depending on config options. Newer versions of binutils detect references from retained sections to discarded sections and flag an error. Pointers to __devexit functions must use __devexit_p(function_name), the wrapper will insert either the function_name or NULL, depending on the config options. */ Signed-off-by: Grant Grundler <grundler@parisc-linux.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-01-22PCI: rework Documentation/pci.txtGrant Grundler
Rewrite Documentation/pci.txt: o restructure document to match how API is used when writing init code. o update to reflect changes in struct pci_driver function pointers. o removed language on "new style vs old style" device discovery. "Old style" is now deprecated. Don't use it. Left description in to document existing driver behaviors. o add section "Legacy I/O Port free driver" by Kenji Kaneshige http://lkml.org/lkml/2006/11/22/25 (renamed to "pci_enable_device_bars() and Legacy I/O Port space") o add "MMIO space and write posting" section to help avoid common pitfall when converting drivers from IO Port space to MMIO space. Orignally posted http://lkml.org/lkml/2006/2/27/24 o many typo/grammer/spelling corrections from Randy Dunlap o two more spelling corrections from Stephan Richter o fix CodingStyle as per Randy Dunlap Signed-off-by: Grant Grundler <grundler@parisc-linux.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

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!
