* iwlwifi: pcie: fix interrupt coalescing for 7260 / 3160Emmanuel Grumbach2014-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | commit 6960a059b2c618f32fe549f13287b3d2278c09e9 upstream. We changed the timeout for the interrupt coealescing for calibration, but that wasn't effective since we changed that value back before loading the firmware. Since calibrations are notification from firmware and not Rx packets, this doesn't change anyway - the firmware will fire an interrupt straight away regardless of the interrupt coalescing value. Also, a HW issue has been discovered in 7000 devices series. The work around is to disable the new interrupt coalescing timeout feature - do this by setting bit 31 in CSR_INT_COALESCING. This has been fixed in 7265 which means that we can't rely on the device family and must have a hint in the iwl_cfg structure.

* iwlwifi: pcie: enable oscillator for L1 exitEmmanuel Grumbach2014-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 2d93aee152b1758a94a18fe15d72153ba73b5679 upstream. Enabling the oscillator consumes slightly more power (100uA) but allows to make sure that we exit from L1 on time. Not doing so might lead to a PCIe specification violation since we might wake up from L1 at the wrong time. This issue has been identified on 3160 and 7260 only. On older NICs L1 off is not enabled, on newer NICs (7265), the issue is fixed. When the bug occurs the user sees that the NIC has disappeared from the PCI bridge, any access to the device returns 0xff. This fixes: https://bugzilla.kernel.org/show_bug.cgi?id=64541 and has been extensively discussed here: http://markmail.org/thread/mfmpzqt3r333n4bo Fixes: 99cd47142399 ("iwlwifi: add 7000 series device configuration") Reported-and-tested-by: wzyboy <wzyboy@wzyboy.org> Reviewed-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* | iwlwifi: use coherent DMA memory for command headerJohannes Berg2013-02-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recently in commit 8a964f44e01ad3bbc208c3e80d931ba91b9ea786 ("iwlwifi: always copy first 16 bytes of commands") we fixed the problem that the hardware writes back to the command and that could overwrite parts of the data that was still needed and would thus be corrupted. Investigating this problem more closely we found that this write-back isn't really ordered very well with respect to other DMA traffic. Therefore, it sometimes happened that the write-back occurred after unmapping the command again which is clearly an issue and could corrupt the next allocation that goes to that spot, or (better) cause IOMMU faults. To fix this, allocate coherent memory for the first 16 bytes of each command, containing the write-back part, and use it for all queues. All the dynamic DMA mappings only need to be TO_DEVICE then. This ensures that even when the write-back happens "too late" it can't hit memory that has been freed or a mapping that doesn't exist any more. Since now the actual command is no longer modified, we can also remove CMD_WANT_HCMD and get rid of the DMA sync that was necessary to update the scratch pointer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The reason we mapped them bidirectionally was that not doing so had caused IOMMU exceptions, due to the fact that the HW writes back into the command. Now that the first part of the command including the write-back part is always in the first buffer, we don't need to map the remaining buffer(s) bidi and can get rid of the special-casing for commands. This is a requisite patch for another one to fix DMA mapping. Reviewed-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* | iwlwifi: always copy first 16 bytes of commandsJohannes Berg2013-02-26
|/ | | | | | | | | | | | | | | | | | | The FH hardware will always write back to the scratch field in commands, even host commands not just TX commands, which can overwrite parts of the command. This is problematic if the command is re-used (with IWL_HCMD_DFL_NOCOPY) and can cause calibration issues. Address this problem by always putting at least the first 16 bytes into the buffer we also use for the command header and therefore make the DMA engine write back into this. For commands that are smaller than 16 bytes also always map enough memory for the DMA engine to write back to.

| | | | | | | | | | | | | | | | | | | | | | With new transports coming up, move to threaded interrupt handling now. This has the advantage that we can use the same locking scheme with all different transports we may need to implement. Note that the TX path obviously still runs in a tasklet, so some spin_lock() calls need to change to spin_lock_bh() calls to properly lock out the TX path. In my test on a Calpella platform this has no impact on throughput or latency. Also add lockdep annotations to avoid lockups due to catch sending synchronous commands or using locks that connect with them from the irq thread.
