| * firewire: fix synchronization of gap countsStefan Richter2008-04-182-8/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | Fix: The fact that nodes had different gap counts would be overlooked if the bus manager code would pick gap count 63 because of beta repeaters or because of very large hop counts. In this case, the bus manager code would miss that it actually has to send the PHY config packet with gap count 63. Related trivial changes: Use bool for an int used as bool, touch up some comments.

| * firewire: reread config ROM when device reset the busStefan Richter2008-04-187-47/+223
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a device changes its configuration ROM, it announces this with a bus reset. firewire-core has to check which node initiated a bus reset and whether any unit directories went away or were added on this node. Tested with an IOI FWB-IDE01AB which has its link-on bit set if bus power is available but does not respond to ROM read requests if self power is off. This implements - recognition of the units if self power is switched on after fw-core gave up the initial attempt to read the config ROM, - shutdown of the units when self power is switched off. Also tested with a second PC running Linux/ieee1394. When the eth1394 driver is inserted and removed on that node, fw-core now notices the addition and removal of the IPv4 unit on the ieee1394 node.

| * firewire: fw-ohci: work around generation bug in TI controllers (fix AV/C ↵Stefan Richter2008-04-181-5/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and more) Unlike the ohci1394 driver, fw-ohci uses the selfIDGeneration field of bus reset packets to determine the generation of incoming requests as per OHCI 1.1 clause 8.4.2.3. This is more precise --- provided that the controller inserts the correct generation. Texas Instruments chips often don't. This prevented the transmission of response packets, which for example broke AV/C transactions as used when communicating with miniDV cameras and any other AV/C devices. There is apparently no way to detect and adjust incorrect generations. Therefore we ignore the generation of bus reset packets from TI chips and use the generation of the self ID buffer instead. Alas this is received at a slightly wrong time. In rare cases, this could cause us to not respond to legitimate requests or to respond to expired requests. (The latter is less likely because the bus reset packet AR event is typically handled before the self ID complete event.) Bug reported by Mladen Kuntner, who was extraordinarily patient while dealing with the driver maintainers. Fix confirmed to be required and effective for TSB82AA2 and a TSB43AB22 or TSB43AB22A. https://bugzilla.redhat.com/show_bug.cgi?id=243081 Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Jarod Wilson <jwilson@redhat.com>
| * firewire: fw-ohci: extend logging of bus generations and node IDStefan Richter2008-04-181-5/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Extend the logging of "AR evt_bus_reset, link internal" to "AR evt_bus_reset, generation ${selfIDGeneration}". That way we can check whether this generation matches the one seen in self ID complete event logging. See OHCI 1.1 clause 8.4.2.3. Also extend logging of "firewire_ohci: * selfIDs, generation *" by "local node ID ffc*" in self ID logging to make the local node in AT/AR event logs more obvious.

| * firewire: fw-ohci: conditionally log busReset interruptsStefan Richter2008-04-181-8/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a debug option to watch bus reset interrupt events. Half of this patch is taken from Jarod Wilson's first version of the JMicron fix. BusReset interrupts are only generated if the respective module parameter flag was set before the controller is being initialized. Else we keep this event masked to reduce IRQ load in normal operation and to avoid potential problems with buggy chips. Note, this is unlike the other IRQ events whose logging can be enabled any time after chip initialization. This and the influence on what interrupts the chip generates is why I added an extra flag for it. Also, reorder the debug parameter flags according to their perceived usefulness.

| * firewire: fw-ohci: don't append to AT context when it's not activeJarod Wilson2008-04-181-2/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I finally tracked down the issues with this JMicron PCI-e card in my possession to a failure to comply with section 7.2.3.2 of the OHCI 1.1 specification (thanks to Kristian for the pointer to illustrate that it is indeed a flaw in this card, not the driver). The controller should simply flush the packets we've appended to its AT queue if a bus reset occurs before they've been transmitted and we'll try again, but something goes wrong and the controller winds up hung. However, we can avoid the problem by simply checking if the IntEvent.busReset register had been set before we try appending to the AT context. When busReset is set, the AT context is completely halted until busReset is cleared, so there's no point in appending AT packets until the register is cleared. So at_context_queue_packet() now checks for busReset being set, and bails with an RCODE_GENERATION packet ack, which results in us trying to append the packet again after recognizing the fact there has been a bus reset, and clearing busReset.

| | | | | | | | | | | | | | | | | | | | While trying to debug this piece of crap JMicron PCI-e controller in my possession, one thought was that perhaps I was encountering register access failures. I'm not, but logging them would be good, so we can see if they are a real problem we should be taking into account anywhere in the code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've now witnessed multiple occasions where one of my controllers (a very poorly working JMicron PCIe card) fails to get its registers properly set up in ohci_enable(), apparently due to an occasionally very slow to initiate SClk. The easy fix for this problem is to add a tiny while loop to try again a time or three after initially enabling LPS before we move on (or give up). Of course, the card still isn't fully functional yet, but this gets it at least one tiny step closer...

| | | | | | | | | | | | | | | | | | | | | | | | | | fw_core_handle_bus_reset() incorrectly relied on the assumption that self_id_count > 0. We check early in fw-ohci and discard the self ID complete event if self_id_count == 0 because a valid event always has at least one self ID packet in it (the one of the local node).

The information includes the list of sockets (sock_containers) as well as the list of outstanding messages (send_tracking). Useful for o2dlm debugging. (This patch is derived from an earlier one written by Zach Brown that exposed the same information via /proc.)

| * | ocfs2: Only build ocfs2/dlm with the o2cb stack moduleMark Fasheh2008-04-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fs/ocfs2/dlm/ocfs2_dlm.ko and fs/ocfs2/dlm/ocfs2_dlmfs.ko get built if CONFIG_FS_OCFS2 is specified. This isn't quite how it should happen any more - the "o2cb" dlm modules should only be built if CONFIG_FS_OCFS2_O2CB is set, so update the dlm Makefile accordingly.

| * | ocfs2/cluster: Get rid of arguments to the timeout routinesJeff Mahoney2008-04-181-27/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We keep seeing bug reports related to NULL pointer derefs in o2net_set_nn_state(). When I originally wrote up the configurable timeout patch, I had tried to plan for multiple clusters. This was silly. The timeout routines all use o2nm_single_cluster so there's no point in passing an argument at all. This patch removes the arguments and kills those bugs dead.
