* Device megapatch 1/6:Poul-Henning Kamp2004-02-21103-291/+4
| | | | | | | | | | Free approx 86 major numbers with a mostly automatically generated patch. A number of strategic drivers have been left behind by caution, and a few because they still (ab)use their major number. Notes: svn path=/head/; revision=126076

* Don't remove the first mbuf in the chain if it got empty.Hartmut Brandt2004-02-211-7/+6
| | | | | | | | | | | This removes the packet header in certain cases which later on will give panic. Clarify what the atm_intr expects in the comment and de-obscurify the code a little bit by replacing the portability macros with the BSD names. The code isn't maintained externally anymore so there's no point in keeping the extra level of obscurity. Notes: svn path=/head/; revision=126063

* Switch to using the new $PIR interrupt routing code and remove the oldJohn Baldwin2004-02-184-436/+22
| | | | | | | | code. The pci_cfgreg.c file now just controls reading/writing PCI config registers. Notes: svn path=/head/; revision=125981
* Rework the $PIR (aka PCIBIOS) PCI interrupt routing code and split it offJohn Baldwin2004-02-181-609/+445
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | into its own file: - All of the $PIR interrupt routing is now done in a link-centric fashion. When a host-PCI bridge that uses the $PIR attaches, it calls pir_parse() to parse the table. This scans for link devices and merges all the masks for each link device from the table entries. It then looks at the intline register of PCI devices connected to a link to figure out if the BIOS has routed this link and if so to which IRQ. - The IRQ for any given link can be overridden via a hint like so: 'hw.pci.link.0x62.irq=10' Any IRQ set in this matter is treated as if it were set that way by the BIOS. - We only call the BIOS to route each link device once. - When a PCI device wants to route an interrupt, we look it up in the $PIR to find the associated link. If the link is routed, we simply return the IRQ it is using. If it is not routed, we have to pick one. This uses a different algorithm from the old code. First off, when we try to pick an interrupt from a mask of possible interrupts, we try to pick the one that is least loaded as far as PCI devices. We maintain this weight based on the number of devices attached to each link device. When choosing an IRQ, we first attempt to route using any PCI only interrupts (the old code did this as well). If that doesn't work, we try to use the list of IRQs that the BIOS has used. This is a new step that the new code didn't do and avoids using IRQ 3 or 4 for every virgin interrupt routing. If none of the IRQs that the BIOS used worked, then we fall back to trying anything. - The fallback mask for !PC98 was fixed to include IRQ 3 and not allow IRQ 2. - We don't use the $PIR to route interrupts on a PCI-PCI bridge unless it has already been used to route on at least one Host-PCI bridge. This helps to avoid mixing and matching x86 firmware PCI interrupt routing methods (which is a Bad Thing(tm)). Silence on: current@ Notes: svn path=/head/; revision=125980
* Change the disk(9) API in order to make device removal more robust.Poul-Henning Kamp2004-02-1828-273/+335
| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously the "struct disk" were owned by the device driver and this gave us problems when the device disappared and the users of that device were not immediately disappearing. Now the struct disk is allocate with a new call, disk_alloc() and owned by geom_disk and just abandonned by the device driver when disk_create() is called. Unfortunately, this results in a ton of "s/\./->/" changes to device drivers. Since I'm doing the sweep anyway, a couple of other API improvements have been carried out at the same time: The Giant awareness flag has been flipped from DISKFLAG_NOGIANT to DISKFLAG_NEEDSGIANT A version number have been added to disk_create() so that we can detect, report and ignore binary drivers with old ABI in the future. Manual page update to follow shortly. Notes: svn path=/head/; revision=125975
