2008-05-11i2c: Convert some more new-style drivers to use module aliasingJean Delvare3-1/+25
Update 3 more new-style i2c drivers to use standard module aliasing instead of the old driver_name/type driver matching scheme. These video drivers aren't used yet so converting them is trivial. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-05-11i2c: Match dummy devices by typeJean Delvare2-7/+9
As the old driver_name/type matching scheme is going away soon, change the dummy device mechanism to use the new matching scheme. This has the downside that dummy i2c clients can no longer choose their name, they'll all appear as "dummy" in sysfs and in log messages. I don't think it is a problem in practice though, as there is little reason to use these i2c clients to log messages. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-05-11i2c-sibyte: Mark i2c_sibyte_add_bus() as staticMaciej W. Rozycki1-1/+1
The i2c_sibyte_add_bus() function is not called, nor meant to, from outside, so mark it as static; fixing a sparse warning too. Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-05-11i2c-sibyte: Correct a comment about frequencyMaciej W. Rozycki1-2/+2
The frequency may have been once hardcoded to 100 kHz, but currently it is passed as an argument to i2c_sibyte_add_bus(), so update the comment to match code. While at it, reformat a nearby comment for consistency. No functional changes. Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-05-11i2c-piix4: Blacklist two mainboardsJean Delvare1-2/+30
We had a report that running sensors-detect on a Sapphire AM2RD790 motherbord killed the CPU. While the exact cause is still unknown, I'd rather play it safe and prevent any access to the SMBus on that machine by not letting the i2c-piix4 driver attach to the SMBus host device on that machine. Also blacklist a similar board made by DFI. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-05-11i2c-piix4: Increase the intitial delay for the ServerWorks CSB5David Milburn1-3/+12
Per the PIIX4 errata, there maybe a delay between setting the start bit in the Smbus Host Controller Register and the transaction actually starting. If the driver doesn't delay long enough, it may appear that the transaction is complete when actually it hasn't started, this may lead to bus collisions. While 1 ms appears to be enough for most chips, the ServerWorks CSB5 wants 2 ms. Signed-off-by: David Milburn <dmilburn@redhat.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-05-11i2c-mpc: Compare to NO_IRQ instead of zeroJon Smirl1-9/+7
Alter the mpc i2c driver to use the NO_IRQ symbol instead of the constant zero when checking for valid interrupts. NO_IRQ=-1 on ppc and NO_IRQ=0 on powerpc so the checks against zero are not correct. Signed-off-by: Jon Smirl <jonsmirl@gmail.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>

The reason is that it tries to clean up the macvlan_port pointer on the macvlan device itself instead of the underlying device. A non-NULL pointer is taken as indication that the macvlan_handle_frame_hook is valid, when receiving the next packet on the underlying device it tries to call the NULL hook and crashes.

2008-05-07IB/ipath: Fix SDMA error recovery in absence of link status changeJohn Gregor2-10/+29
What's fixed: in ipath_cancel_sends() We need to unconditionally set ABORTING. So, swap the tests so the set_bit() isn't shadowed by the &&. If we've disarmed the piobufs, then we need to unconditionally set DISARMED. So, move it out from the overly protective if at the bottom. in sdma_abort_task() Abort_task was written knowing that the SDMA engine would always be reset (and restarted) on error. A recent change broke that fundamental assumption by taking the restart portion and making it conditional on a link status change. But, SDMA can go boom without a link status change in some conditions. Signed-off-by: John Gregor <john.gregor@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2008-05-07IB/ipath: Need to always request and handle PIO avail interruptsDave Olson8-202/+224
Now that we always use PIO for vl15 on 7220, we could get stuck forever if we happened to run out of PIO buffers from the verbs code, because the setup code wouldn't run; the interrupt was also ignored if SDMA was supported. We also have to reduce the pio update threshold if we have fewer kernel buffers than the existing threshold. Clean up the initialization a bit to get ordering safer and more sensible, and use the existing ipath_chg_kernavail call to do init, rather than doing it separately. Drop unnecessary clearing of pio buffer on pio parity error. Drop incorrect updating of pioavailshadow when exitting freeze mode (software state may not match chip state if buffer has been allocated and not yet written). If we couldn't get a kernel buffer for a while, make sure we are in sync with hardware, mainly to handle the exitting freeze case.

2008-05-07IB/ipath: Fix bug that can leave sends disabled after freeze recoveryDave Olson1-2/+6
The semantics of cancel_sends changed, but the code using it was missed. Don't leave sends and pioavail updates disabled, and add a comment as to why the force update is needed. Signed-off-by: Dave Olson <dave.olson@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2008-05-07IB/ipath: Only increment SSN if WQE is put on send queueRalph Campbell1-1/+1
If a send work request has immediate errors and is not put on the send queue, we shouldn't update any of the QP state. The increment of the SSN wasn't obeying this. Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2008-05-07IB/ipath: Only warn about prototype chip during initMichael Albaugh1-2/+3
We warn about prototype chips, but the function that checks for support is also called as a result of a get_portinfo request, which can clutter the logs. Restrict warning to only appear during initialization. Signed-off-by: Michael Albaugh <michael.albaugh@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
