* Make the PCI code aware of PCI domains (aka PCI segments) so we canMarius Strobl2007-09-303-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | support machines having multiple independently numbered PCI domains and don't support reenumeration without ambiguity amongst the devices as seen by the OS and represented by PCI location strings. This includes introducing a function pci_find_dbsf(9) which works like pci_find_bsf(9) but additionally takes a domain number argument and limiting pci_find_bsf(9) to only search devices in domain 0 (the only domain in single-domain systems). Bge(4) and ofw_pcibus(4) are changed to use pci_find_dbsf(9) instead of pci_find_bsf(9) in order to no longer report false positives when searching for siblings and dupe devices in the same domain respectively. Along with this change the sole host-PCI bridge driver converted to actually make use of PCI domain support is uninorth(4), the others continue to use domain 0 only for now and need to be converted as appropriate later on. Note that this means that the format of the location strings as used by pciconf(8) has been changed and that consumers of <sys/pciio.h> potentially need to be recompiled.

* Migrate from setting a CARD_OK flag in a shared word, to setting itsWarner Losh2007-06-043-32/+21
| | | | | | | | | | | | | | own entry in the softc. This should allow more of cbb_pci_intr() to migrate to a new cbb_pci_filt() so that we don't have to run cbb's ISR in almost every case we get an interrupt. We can't just move cbb_pci_intr into cbb_pci_filt because it does things that aren't safe to do from a fast interrupt handler, err I mean from a filter. This is an important first step. # I wonder if I need to make cardok volatile or not. Notes: svn path=/head/; revision=170272

* Minor filter tweaks:Warner Losh2007-06-031-26/+47
| | | | | | | | | | | | | | | | | | | | o If we don't have a filter, also check to make sure the card is there before calling the scheduled ISR. This is necessary to help old drivers whose ISRs can't cope with being called with the hardware missing, which sadly still exist in the tree. This is the main reason why we have an extra layer of indirection for cardbus interrupts. o If the card is no longer present, mark the interrupt as 'handled' rather than 'stray' because this accounts for why the interrupt happened. Stray isn't all bad, since there are other filters that would claim it... o Fix some comments + Add comment about why we check for CARD_OK and touch the hardware in both the filter and ISR. + add a note about why we don't care about Giant + also note that giant can't be taken out in a filter... + Some minor formatting nits on very long comments.

* Two changes:Warner Losh2007-02-161-1/+4
| | | | | | | | | | | | | | | | | (1) change debounce period from 1s to 250ms. This appears to be fine and speeds things up a little. (2) In the middle of cbb_pcic_power_disable_socket we write 0 to the EXCA_INTR register to put the card into reset. However, this turns off CSC interrupts for TI bridges (and maybe others). So no further card insertion events would be noticed. To compensate, after we've gone through the entire power down sequence, turn on EXCA_INTR_ENABLE so that CSC events happen. #2 should fix the 'dead slot' problem that has been reported after card ejection (but only 16-bit cards).

| | | | | | | | | | | device pointers. They don't change as the children device drivers come and go. Rather, check to see if the device is attached where we would have checked ! NULL. This solves many asymmetries in the code that likely could lead to crashes when loading/unloading cbb without one or more of the expected children's driver not present.

* Fix three bugs:Warner Losh2007-02-151-6/+25
| | | | | | | | | | | | | o When detaching all children, try really hard to get all the children list before giving up. This is based on an observation by hans petter selasky in his usb p4 branch. o When rescanning devices after a driver is added, abort if we can't get the child list with a message. o when rescanning devices, if the reprobe/attach is successful, save the device for cardbus/pccard.

* Batch of changes:Warner Losh2006-08-123-61/+112
| | | | | | | | | | | | | | | | | | | | | | o when turning off the socket for a 16-bit card, write 0 to INTR register rather than just tying to just clear the rest bit. this seems to fix card insert detection after an eject on TI bridges (ricoh bridges work either way, apparently). This is a MFp4. o Cope better with TOPIC95 bridges on powerup. According to NetBSD driver, these bridges don't set POWER_STATE, so cope accordingly in our power code. They also need a little extra time to settle, so do that as well. o It appears that we need to turn on/off one of the clocks to the card when we power up/down that socket on a TOPIC97, also from NetBSD. o TOPIC97 bridges need to specifically enable LV card support. Unconditionally do this in the hopes that all laptops that have these chips support LV voltages (they should, since they are required for CardBus). o TOPIC register name regularization. Registers specific to models of TOPIC are now called out as such. # I need a machine with a TOPIC95 for testing. Notes: svn path=/head/; revision=161241

This totally violates the PCI spec, but happens rarely enough that a workaround is in order. This adds one test when we have a real interrupt to service (which is very rare), and doesn't affect the usualy 'nothing to see here' case at all.
