2017-06-14RDMA/bnxt_re: Fix RQE posting logicDevesh Sharma
This patch adds code to ring RQ Doorbell aggressively so that the adapter can DMA RQ buffers sooner, instead of DMA all WQEs in the post_recv WR list together at the end of the post_recv verb.

2017-06-14RDMA/bnxt_re: Add HW workaround for avoiding stall for UD QPsSomnath Kotur
HW stalls out after 0x800000 WQEs are posted for UD QPs. To workaround this problem, driver will send a modify_qp cmd to the HW at around the halfway mark(0x400000) so that FW can accordingly modify the QP context in the HW to prevent this stall. This workaround needs to be done for UD, QP1 and Raw Ethertype packets. Added a counter to keep track of WQEs posted during post_send.

2017-06-14RDMA/bnxt_re: HW workarounds for handling specific conditionsEddie Wai
This patch implements the following HW workarounds 1. The SQ depth needs to be augmented by 128 + 1 to avoid running into an Out of order CQE issue 2. Workaround to handle the problem where the HW fast path engine continues to access DMA memory in retranmission mode even after the WQE has already been completed. If the HW reports this condition, driver detects it and posts a Fence WQE. The driver stops reporting the completions to stack until it receives completion for Fence WQE.

2017-06-13HID: let generic driver yield control iff specific driver has been enabledJiri Kosina
There are many situations where generic HID driver provides some basic level of support for certain device, but later this support (usually by implementing vendor-specific extensions of HID protocol) is extended and the support moved over to a separate (usually per-vendor) specific driver. This might bring a rather unpleasant suprise for users, as all of a sudden there is a new config option they have to enable in order to get any support for their device whatsoever, although previous kernel versions provided basic support through the generic driver. Which is rightfully seen as a regression. Fix this by including the entry for a particular device in hid_have_special_driver[] iff the specific config option has been specified, and let generic driver handle the device otherwise. Also make the behavior of hid_scan_report() (where the same decision is being taken on a per-report level) consistent. While at it, reshuffle the hid_have_special_driver[] a bit to restore the alphabetical ordering (first order by config option, and within those sections order by VID). This is considered a short-term solution, before generic way of giving precedence to special drivers and falling back to generic driver is figured out. While at it, fixup a missing entry for GFRM driver; thanks to Hans de Geode for spotting this (and for discovering a few issues in the conversion). Signed-off-by: Jiri Kosina <jkosina@suse.cz>

Starting from commit b63a16f6cd89 ("drm/i915: Compute display surface offset in the plane check hook for SKL+") we've already rotated the src coordinates by 270 degrees by the time we check if a scaler is needed or not, so we must not account for the rotation a second time. Previously we did these steps in the opposite order and hence the scaler check had to deal with rotation itself. The double rotation handling causes us to enable a scaler pretty much every time 90/270 degree plane rotation is requested, leading to fuzzier fonts and whatnot. v2: s/unsigned/unsigned int/ to appease checkpatch v3: s/DRM_ROTATE_0/DRM_MODE_ROTATE_0/ Cc: stable@vger.kernel.org Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reported-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Tested-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Fixes: b63a16f6cd89 ("drm/i915: Compute display surface offset in the plane check hook for SKL+") Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170331180056.14086-2-ville.syrjala@linux.intel.com Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> (cherry picked from commit d96a7d2adb040a67e163a82dad6316f9f572498a) Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170608144002.1605-1-ville.syrjala@linux.intel.com

2017-06-12i40e: fix handling of HW ATR evictionJacob Keller
A recent commit to refactor the driver and remove the hw_disabled_flags field accidentally introduced two regressions. First, we overwrote pf->flags which removed various key flags including the MSI-X settings. Additionally, it was intended that we have now two flags, HW_ATR_EVICT_CAPABLE and HW_ATR_EVICT_ENABLED, but this was not done, and we accidentally were mis-using HW_ATR_EVICT_CAPABLE everywhere. This patch adds the missing piece, HW_ATR_EVICT_ENABLED, and safely updates pf->flags instead of overwriting it. Without this patch we will have many problems including disabling MSI-X support, and we'll attempt to use HW ATR eviction on devices which do not support it.

2017-06-12usb: xhci: Fix USB 3.1 supported protocol parsingYD Tseng
xHCI host controllers can have both USB 3.1 and 3.0 extended speed protocol lists. If the USB3.1 speed is parsed first and 3.0 second then the minor revision supported will be overwritten by the 3.0 speeds and the USB3 roothub will only show support for USB 3.0 speeds. This was the case with a xhci controller with the supported protocol capability listed below. In xhci-mem.c, the USB 3.1 speed is parsed first, the min_rev of usb3_rhub is set as 0x10. And then USB 3.0 is parsed. However, the min_rev of usb3_rhub will be changed to 0x00. If USB 3.1 device is connected behind this host controller, the speed of USB 3.1 device just reports 5G speed using lsusb. 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 00 01 08 00 00 00 00 00 40 00 00 00 00 00 00 00 00 10 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 20 02 08 10 03 55 53 42 20 01 02 00 00 00 00 00 00 //USB 3.1 30 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 40 02 08 00 03 55 53 42 20 03 06 00 00 00 00 00 00 //USB 3.0 50 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 60 02 08 00 02 55 53 42 20 09 0E 19 00 00 00 00 00 //USB 2.0 70 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 This patch fixes the issue by only owerwriting the minor revision if it is higher than the existing one.

2017-06-12cpufreq: conservative: Allow down_threshold to take values from 1 to 10Tomasz Wilczyński
Commit 27ed3cd2ebf4 (cpufreq: conservative: Fix the logic in frequency decrease checking) removed the 10 point substraction when comparing the load against down_threshold but did not remove the related limit for the down_threshold value. As a result, down_threshold lower than 11 is not allowed even though values from 1 to 10 do work correctly too. The comment ("cannot be lower than 11 otherwise freq will not fall") also does not apply after removing the substraction. For this reason, allow down_threshold to take any value from 1 to 99 and fix the related comment.

2017-06-12ACPICA: Tables: Mechanism to handle late stage acpi_get_table() imbalanceLv Zheng
Considering this case: 1. A program opens a sysfs table file 65535 times, it can increase validation_count and first increment cause the table to be mapped: validation_count = 65535 2. AML execution causes "Load" to be executed on the same table, this time it cannot increase validation_count, so validation_count remains: validation_count = 65535 3. The program closes sysfs table file 65535 times, it can decrease validation_count and the last decrement cause the table to be unmapped: validation_count = 0 4. AML code still accessing the loaded table, kernel crash can be observed. To prevent that from happening, add a validation_count threashold. When it is reached, the validation_count can no longer be incremented/decremented to invalidate the table descriptor (means preventing table unmappings) Note that code added in acpi_tb_put_table() is actually a no-op but changes the warning message into a "warn once" one.

2017-06-11net: ena: fix theoretical Rx hang on low memory systemsNetanel Belgazal
For the rare case where the device runs out of free rx buffer descriptors (in case of pressure on kernel memory), and the napi handler continuously fail to refill new Rx descriptors until device rx queue totally runs out of all free rx buffers to post incoming packet, leading to a deadlock: * The device won't send interrupts since all the new Rx packets will be dropped. * The napi handler won't try to allocate new Rx descriptors since allocation is part of NAPI that's not being invoked any more The fix involves detecting this scenario and rescheduling NAPI (to refill buffers) by the keepalive/watchdog task.
