* [PATCH] pcmcia: defer ide-cs initialization after other IDE drivers started upDominik Brodowski2005-08-01
| | | | | | | | | Avoid registering PCMCIA CF cards before other IDE stuff. This means the risk of /dev/hd* being re-ordered is lessened.

* [PATCH] clean up inline static vs static inlineJesper Juhl2005-07-27
| | | | | | | | | | | | | | | `gcc -W' likes to complain if the static keyword is not at the beginning of the declaration. This patch fixes all remaining occurrences of "inline static" up with "static inline" in the entire kernel tree (140 occurrences in 47 files). While making this change I came across a few lines with trailing whitespace that I also fixed up, I have also added or removed a blank line or two here and there, but there are no functional changes in the patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dynamic pci id logic has been bothering me for a while, and now that I started to look into how to move some of this to the driver core, I thought it was time to clean it all up. It ends up making the code smaller, and easier to follow, and fixes a few bugs at the same time (dynamic ids were not being matched everywhere, and so could be missed on some call paths for new devices, semaphore not needed to be grabbed when adding a new id and calling the driver core, etc.) I also renamed the function pci_match_device() to pci_match_id() as that's what it really does.

* [PATCH] IDE CD reports current speedEric Piel2005-06-23
| | | | | | | | | | | | | | | | | | | | The current ide-cd driver reports the CDROM speed (as found in /proc/sys/dev/cdrom/info) as the current speed when loading the driver. Changing the speed of the cdrom drive (by "eject -x" for instance) doesn't update the speed reported by the kernel. Updating the info could be valuable for the user as it's the only way to know if the drive accepted the request or discarded it. It could even be used to list all the available speeds of the drive. The attached patch modifies the ide-cd driver so that after every speed change request the new speed is updated. Please note that the actual modification is very little but I had to touch quite a few lines in order to avoid to pre-declare the sub-functions.

* [PATCH] ioc4: Core driver rewriteBrent Casavant2005-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This series of patches reworks the configuration and internal structure of the SGI IOC4 I/O controller device drivers. These changes are motivated by several factors: - The IOC4 chip PCI resources are of mixed use between functions (i.e. multiple functions are handled in the same address range, sometimes within the same register), muddling resource ownership and initialization issues. Centralizing this ownership in a core driver is desirable. - The IOC4 chip implements multiple functions (serial, IDE, others not yet implemented in the mainline kernel) but is not a multifunction PCI device. In order to properly handle device addition and removal as well as module insertion and deletion, an intermediary IOC4-specific driver layer is needed to handle these operations cleanly. - All IOC4 drivers are currently enabled by a single CONFIG value. As not all systems need all IOC4 functions, it is desireable to enable these drivers independently. - The current IOC4 core driver will trigger loading of all function-level drivers, as it makes direct calls to them. This situation should be reversed (i.e. function-level drivers cause loading of core driver) in order to maintain a clear and least-surprise driver loading model. - IOC4 hardware design necessitates some driver-level dependency on the PCI bus clock speed. Current code assumes a 66MHz bus, but the speed should be autodetected and appropriate compensation taken. This patch series effects the above changes by a newly and better designed IOC4 core driver with which the function-level drivers can register and deregister themselves upon module insertion/removal. By tracking these modules, device addition/removal is also handled properly. PCI resource management and ownership issues are centralized in this core driver, and IOC4-wide configuration actions such as bus speed detection are also handled in this core driver. This patch: The SGI IOC4 I/O controller chip implements multiple functions, though it is not a multi-function PCI device. Additionally, various PCI resources of the IOC4 are shared by multiple hardware functions, and thus resource ownership by driver is not clearly delineated. Due to the current driver design, all core and subordinate drivers must be loaded, or none, which is undesirable if not all IOC4 hardware features are being used. This patch reorganizes the IOC4 drivers so that the core driver provides a subdriver registration service. Through appropriate callbacks the subdrivers can now handle device addition and removal, as well as module insertion and deletion (though the IOC4 IDE driver requires further work before module deletion will work). The core driver now takes care of allocating PCI resources and data which must be shared between subdrivers, to clearly delineate module ownership of these items.

* [PATCH] timeout at boottime with NEC3500A (and possibly others) when ↵Marcello Maggioni2005-05-26
| | | | | | | | | | | | | | | | | | | | | inserted a CD in it From: Marcello Maggioni <hayarms@gmail.com> Problem: Some drives (NEC 3500, TDK 1616N, Mad-dog MD-16XDVD9, RICOH MP5163DA, Memorex DVD9 drive and IO-DATA's too for sure), if a CD/DVD is inserted into the tray when the system is booted and if before the OS bootup the BIOS checked for the presence of a bootable CD/DVD into the drive, during the IDE probe phase the drive may result busy and remain so for the next 25/30 seconds . This cause the drive to be skipped during the booting phase and not begin usable until the next reboot (if the reboot goes well and the drive doesn't timeout again). Solution: Rising the timeout time from 10 seconds to 35 seconds (during these 35 seconds every drive should wake up for sure according to the tests I've done).
