2014-02-13rtl8187: fix regression on MIPS without coherent DMAStanislaw Gruszka
This patch fixes regression caused by commit a16dad77634 "MIPS: Fix potencial corruption". That commit fixes one corruption scenario in cost of adding another one, which actually start to cause crashes on Yeeloong laptop when rtl8187 driver is used. For correct DMA read operation on machines without DMA coherence, kernel have to invalidate cache, such it will refill later with new data that device wrote to memory, when that data is needed to process. We can only invalidate full cache line. Hence when cache line includes both dma buffer and some other data (written in cache, but not yet in main memory), the other data can not hit memory due to invalidation. That happen on rtl8187 where struct rtl8187_priv fields are located just before and after small buffers that are passed to USB layer and DMA is performed on them. To fix the problem we align buffers and reserve space after them to make them match cache line. This patch does not resolve all possible MIPS problems entirely, for that we have to assure that we always map cache aligned buffers for DMA, what can be complex or even not possible. But patch fixes visible and reproducible regression and seems other possible corruptions do not happen in practice, since Yeeloong laptop works stable without rtl8187 driver.

I think that it is safe doing so since the device interrupt will only be enabled after the init function succeed.

2014-02-06rtl8180: Add error check for pci_map_single return value in RX pathandrea.merello
In original code the old RX DMA buffer is unmapped and processed and at the end of the isr a new buffer is mapped with pci_map_single and attached to the RX descriptor. If pci_map_single fails then the RX descriptor remains with no valid DMA buffer attached. In this condition the DMA will target where it shouldn't with obvious evil consequences. Simply avoiding re-arming the descriptor will prevent buggy DMA but it will result soon in RX stuck. This patch move the DMA mapping of the new buffer at the beginning of the ISR (and it adds error check for pci_map_single success/fail). If the DMA mapping fails then we do not unmap the old buffer and we re-arm the descriptor without processing it, with the old DMA buffer still attached. In this way we lose the currently RX-ed packet, but whenever next calls to pci_map_single will succeed again,then the RX process will go on without stuck.

2014-02-04ath9k_htc: make ->sta_rc_update atomic for most callsStanislaw Gruszka
sta_rc_update() callback must be atomic, hence we can not take mutexes or do other operations, which can sleep in ath9k_htc_sta_rc_update(). I think we can just return from ath9k_htc_sta_rc_update(), if it is called without IEEE80211_RC_SUPP_RATES_CHANGED bit. That will help with scheduling while atomic bug for most cases (except mesh and IBSS modes). For mesh and IBSS I do not see other solution like creating additional workqueue, because sending firmware command require us to sleep, but this can be done in additional patch.

The driver wasn't reading the NVM properly. While this didn't lead to any issue until now, it seems that there is an old version of the NVM in the wild. In this version, the A band channels appear to be valid but the SKU capabilities (another field of the NVM) says that A band isn't supported at all. With this specific version of the NVM, the driver would think that A band is supported while the HW / firmware don't. This leads to asserts.

2014-01-30drm/nouveau: resume display if any later suspend bits failIlia Mirkin
If either idling channels or suspending the fence were to fail, the display would never be resumed. Also if a client fails, resume the fence (not functionally important, but it would potentially leak memory).

2014-01-29drm/radeon: set si_notify_smc_display_change properlyAlex Deucher
This is effectively a revert of 4573388c92ee60b4ed72b8d95b73df861189988c. Forcing a display active when there is none causes problems with dpm on some SI boards which results in improperly initialized dpm state and boot failures on some boards. As for the bug commit 4573388c92ee tried to address, one can manually force the state to high for better performance when using the card as a headless compute node until a better fix is developed. bugs: https://bugs.freedesktop.org/show_bug.cgi?id=73788 https://bugs.freedesktop.org/show_bug.cgi?id=69395 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> cc: stable@vger.kernel.org
