git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma Pull more rdma updates from Doug Ledford: "This is the second group of code for the 4.7 merge window. It looks large, but only in one sense. I'll get to that in a minute. The list of changes here breaks down as follows: - Dynamic counter infrastructure in the IB drivers This is a sysfs based code to allow free form access to the hardware counters RDMA devices might support so drivers don't need to code this up repeatedly themselves - SendOnlyFullMember multicast support - IB router support - A couple misc fixes - The big item on the list: hfi1 driver updates, plus moving the hfi1 driver out of staging There was a group of 15 patches in the hfi1 list that I thought I had in the first pull request but they weren't. So that added to the length of the hfi1 section here. As far as these go, everything but the hfi1 is pretty straight forward. The hfi1 is, if you recall, the driver that Al had complaints about how it used the write/writev interfaces in an overloaded fashion. The write portion of their interface behaved like the write handler in the IB stack proper and did bi-directional communications. The writev interface, on the other hand, only accepts SDMA request structures. The completions for those structures are sent back via an entirely different event mechanism. With the security patch, we put security checks on the write interface, however, we also knew they would be going away soon. Now, we've converted the write handler in the hfi1 driver to use ioctls from the IB reserved magic area for its bidirectional communications. With that change, Intel has addressed all of the items originally on their TODO when they went into staging (as well as many items added to the list later). As such, I moved them out, and since they were the last item in the staging/rdma directory, and I don't have immediate plans to use the staging area again, I removed the staging/rdma area. Because of the move out of staging, as well as a series of 5 patches in the hfi1 driver that removed code people thought should be done in a different way and was optional to begin with (a snoop debug interface, an eeprom driver for an eeprom connected directory to their hfi1 chip and not via an i2c bus, and a few other things like that), the line count, especially the removal count, is high" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (56 commits) staging/rdma: Remove the entire rdma subdirectory of staging IB/core: Make device counter infrastructure dynamic IB/hfi1: Fix pio map initialization IB/hfi1: Correct 8051 link parameter settings IB/hfi1: Update pkey table properly after link down or FM start IB/rdamvt: Fix rdmavt s_ack_queue sizing IB/rdmavt: Max atomic value should be a u8 IB/hfi1: Fix hard lockup due to not using save/restore spin lock IB/hfi1: Add tracing support for send with invalidate opcode IB/hfi1, qib: Add ieth to the packet header definitions IB/hfi1: Move driver out of staging IB/hfi1: Do not free hfi1 cdev parent structure early IB/hfi1: Add trace message in user IOCTL handling IB/hfi1: Remove write(), use ioctl() for user cmds IB/hfi1: Add ioctl() interface for user commands IB/hfi1: Remove unused user command IB/hfi1: Remove snoop/diag interface IB/hfi1: Remove EPROM functionality from data device IB/hfi1: Remove UI char device IB/hfi1: Remove multiple device cdev ...

2016-05-27switch ->setxattr() to passing dentry and inode separatelyAl Viro1-0/+7
smack ->d_instantiate() uses ->setxattr(), so to be able to call it before we'd hashed the new dentry and attached it to inode, we need ->setxattr() instances getting the inode as an explicit argument rather than obtaining it from dentry. Similar change for ->getxattr() had been done in commit ce23e64. Unlike ->getxattr() (which is used by both selinux and smack instances of ->d_instantiate()) ->setxattr() is used only by smack one and unfortunately it got missed back then.

2016-05-26IB/core: Make device counter infrastructure dynamicChristoph Lameter1-0/+12
In practice, each RDMA device has a unique set of counters that the hardware implements. Having a central set of counters that they must all adhere to is limiting and causes many useful counters to not be available. Therefore we create a dynamic counter registration infrastructure. The driver must implement a stats structure allocation routine, in which the driver must place the directory name it wants, a list of names for all of the counters, an array of u64 counters themselves, plus a few generic configuration options. We then implement a core routine to create a sysfs file for each of the named stats elements, and a core routine to retrieve the stats when any of the sysfs attribute files are read. To avoid excessive beating on the stats generation routine in the drivers, the core code also caches the stats for a short period of time so that someone attempting to read all of the stats in a given device's directory will not result in a stats generation call per file read. Future work will attempt to standardize just the shared stats elements, and possibly add a method to get the stats via netlink in addition to sysfs.

Many use-cases don't care about this, but for others it is essential. These new features require changes in all users, which these patches take care of.

2016-05-23drm: Add helper for DP++ adaptorsVille Syrjälä1-0/+6
Add a helper which aids in the identification of DP dual mode (aka. DP++) adaptors. There are several types of adaptors specified: type 1 DVI, type 1 HDMI, type 2 DVI, type 2 HDMI Type 1 adaptors have a max TMDS clock limit of 165MHz, type 2 adaptors may go as high as 300MHz and they provide a register informing the source device what the actual limit is. Supposedly also type 1 adaptors may optionally implement this register. This TMDS clock limit is the main reason why we need to identify these adaptors. Type 1 adaptors provide access to their internal registers and the sink DDC bus through I2C. Type 2 adaptors provide this access both via I2C and I2C-over-AUX. A type 2 source device may choose to implement either of these methods. If a source device implements the I2C-over-AUX method, then the driver will obviously need specific support for such adaptors since the port is driven like an HDMI port, but DDC communication happes over the AUX channel. This helper should be enough to identify the adaptor type (some type 1 DVI adaptors may be a slight exception) and the maximum TMDS clock limit. Another feature that may be available is control over the TMDS output buffers on the adaptor, possibly allowing for some power saving when the TMDS link is down. Other user controllable features that may be available in the adaptors are downstream i2c bus speed control when using i2c-over-aux, and some control over the CEC pin. I chose not to provide any helper functions for those since I have no use for them in i915 at this time. The rest of the registers in the adaptor are mostly just information, eg. IEEE OUI, hardware and firmware revision, etc. v2: Pass adaptor type to helper functions to ease driver implementation Fix a bunch of typoes (Paulo) Add DRM_DP_DUAL_MODE_UNKNOWN for the case where we don't (yet) know the type (Paulo) Reject 0x00 and 0xff DP_DUAL_MODE_MAX_TMDS_CLOCK values (Paulo) Adjust drm_dp_dual_mode_detect() type2 vs. type1 detection to ease future LSPCON enabling Remove the unused DP_DUAL_MODE_LAST_RESERVED define v3: Fix kernel doc function argument descriptions (Jani) s/NONE/UNKNOWN/ in drm_dp_dual_mode_detect() docs Add kernel doc for enum drm_dp_dual_mode_type Actually build the docs Fix more typoes v4: Adjust code indentation of type2 adaptor detection (Shashank) Add debug messages for failurs cases (Shashank) v5: EXPORT_SYMBOL(drm_dp_dual_mode_read) (Paulo) Cc: stable@vger.kernel.org Cc: Tore Anderson <tore@fud.no> Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Cc: Shashank Sharma <shashank.sharma@intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Shashank Sharma <shashank.sharma@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Shashank Sharma <shashank.sharma@intel.com> (v4) Link: http://patchwork.freedesktop.org/patch/msgid/1462542412-25533-1-git-send-email-ville.syrjala@linux.intel.com (cherry picked from commit ede53344dbfd1dd43bfd73eb6af743d37c56a7c3) Signed-off-by: Jani Nikula <jani.nikula@intel.com>
