2018-08-15RDMA/hns: Fix usage of bitmap allocation functions return valuesGal Pressman
hns bitmap allocation functions return 0 on success and -1 on failure. Callers of these functions wrongly used their return value as an errno, fix that by making a proper conversion.

2018-08-15drm/i915: set DP Main Stream Attribute for color range on DDI platformsJani Nikula
Since Haswell we have no color range indication either in the pipe or port registers for DP. Instead, there's a separate register for setting the DP Main Stream Attributes (MSA) directly. The MSA register definition makes no references to colorimetry, just a vague reference to the DP spec. The connection to the color range was lost. Apparently we've failed to set the proper MSA bit for limited, or CEA, range ever since the first DDI platforms. We've started setting other MSA parameters since commit dae847991a43 ("drm/i915: add intel_ddi_set_pipe_settings"). Without the crucial bit of information, the DP sink has no way of knowing the source is actually transmitting limited range RGB, leading to "washed out" colors. With the colorimetry information, compliant sinks should be able to handle the limited range properly. Native (i.e. non-LSPCON) HDMI was not affected because we do pass the color range via AVI infoframes. Though not the root cause, the problem was made worse for DDI platforms with commit 55bc60db5988 ("drm/i915: Add "Automatic" mode for the "Broadcast RGB" property"), which selects limited range RGB automatically based on the mode, as per the DP, HDMI and CEA specs. After all these years, the fix boils down to flipping one bit. [Per testing reports, this fixes DP sinks, but not the LSPCON. My educated guess is that the LSPCON fails to turn the CEA range MSA into AVI infoframes for HDMI.] Reported-by: Michał Kopeć <mkopec12@gmail.com> Reported-by: N.

2018-08-15drm/i915/selftests: Hold rpm for unparkingChris Wilson
The call to i915_gem_unpark() checks that we hold a rpm wakeref before taking a long term wakeref for i915->gt.awake.

2018-08-15drm/i915: Restore user forcewake domains across suspendChris Wilson
On suspend, we cancel the automatic forcewake and clear all other sources of forcewake so the machine can sleep before we do suspend. However, we expose the forcewake to userspace (only via debugfs, but nevertheless we do) and want to restore that upon resume or else our accounting will be off and we may not acquire the forcewake before we use it.

2018-08-15drm/i915: Unmask user interrupts writes into HWSP on snb/ivb/vlv/hswChris Wilson
An oddity occurs on Sandybridge, Ivybridge and Haswell (and presumably Valleyview) in that for the period following the GPU restart after a reset, there are no GT interrupts received. From Ville's notes, bit 0 in the HWSTAM corresponds to the render interrupt, and if we unmask it we do see immediate resumption of GT interrupt delivery (via the master irq handler) after the reset. v2: Limit the w/a to the render interrupt from rcs Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=107500 Fixes: c5498089463b ("drm/i915: Mask everything in ring HWSTAM on gen6+ in ringbuffer mode") References: d420a50c21ef ("drm/i915: Clean up the HWSTAM mess") Testcase: igt/gem_eio/reset-stress Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Acked-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180808105101.913-2-chris@chris-wilson.co.uk (cherry picked from commit a4a717010f4e8cacaa3f0cae8a22f25c39ae1d41) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

2018-08-15PCI/AER: Don't clear AER bits if error handling is Firmware-FirstAlexandru Gagniuc
If the platform requests Firmware-First error handling, firmware is responsible for reading and clearing AER status bits. If OSPM also clears them, we may miss errors. See ACPI v6.2, sec 18.3.2.5 and 18.4. This race is mostly of theoretical significance, as it is not easy to reasonably demonstrate it in testing.

2018-08-15IB/core: Change filter function return type from int to boolParav Pandit
Filter functions returns either 0 or 1, therefore better change their return type from int to bool to reflect the same. Additionally some filter functions have suffix of _filter some doesn't. Make all filter function consistent to have __filter suffix to improve code readability.

2018-08-15IB/core: Add default GIDs of the bond master netdevParav Pandit
Currently following issues exist: 1. Default GIDs of the lower (slave) netdevice if the bond netdevice is added. Rather default GID should be of bond master netdevice. 2. Due to this, when failover event occurs FAILOVER event handler attempts to delete the GID of the upper device and tries to add the default GID of the lower device. This is incorrect behavior. To have simple and correct code: (a) Split default GIDs addition out of add_netdev_ips(). This allows easier removal in future if RoCE default GIDs are removed. (b) Add default GIDs of the bond master device by using right filter and callback function. (c) Remove unused function enum_netdev_default_gids().

2018-08-15IB/core: Delete lower netdevice default GID entries in bonding scenarioParav Pandit
When NETDEV_CHANGEUPPER event occurs, lower device is not yet established as slave of the master, and when upper device is bond device, default GID entries not deleted. Due to this, when bond device is fully configured, default GID entries of bond device cannot be added as default GID entries are occupied by the lower netdevice. This is incorrect. Default GID entries should really be of bond netdevice because in all RoCE GIDs (default or IP), MAC address of the bond device will be used. It is confusing to have default GID of netdevice which is not really used for any purpose. Therefore, as first step, implement (a) filter function which filters if a CHANGEUPPER event netdevice and associated upper device is master device or not. (b) callback function which deletes the default GIDs of lower (event netdevice).
