2016-12-22Merge branch 'x86-cache-for-linus' of ↵Linus Torvalds1-0/+5
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 cache allocation interface from Thomas Gleixner: "This provides support for Intel's Cache Allocation Technology, a cache partitioning mechanism. The interface is odd, but the hardware interface of that CAT stuff is odd as well. We tried hard to come up with an abstraction, but that only allows rather simple partitioning, but no way of sharing and dealing with the per package nature of this mechanism. In the end we decided to expose the allocation bitmaps directly so all combinations of the hardware can be utilized. There are two ways of associating a cache partition: - Task A task can be added to a resource group. It uses the cache partition associated to the group. - CPU All tasks which are not member of a resource group use the group to which the CPU they are running on is associated with. That allows for simple CPU based partitioning schemes. The main expected user sare: - Virtualization so a VM can only trash only the associated part of the cash w/o disturbing others - Real-Time systems to seperate RT and general workloads. - Latency sensitive enterprise workloads - In theory this also can be used to protect against cache side channel attacks" [ Intel RDT is "Resource Director Technology". The interface really is rather odd and very specific, which delayed this pull request while I was thinking about it. The pull request itself came in early during the merge window, I just delayed it until things had calmed down and I had more time. But people tell me they'll use this, and the good news is that it is _so_ specific that it's rather independent of anything else, and no user is going to depend on the interface since it's pretty rare. So if push comes to shove, we can just remove the interface and nothing will break ] * 'x86-cache-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (31 commits) x86/intel_rdt: Implement show_options() for resctrlfs x86/intel_rdt: Call intel_rdt_sched_in() with preemption disabled x86/intel_rdt: Update task closid immediately on CPU in rmdir and unmount x86/intel_rdt: Fix setting of closid when adding CPUs to a group x86/intel_rdt: Update percpu closid immeditately on CPUs affected by changee x86/intel_rdt: Reset per cpu closids on unmount x86/intel_rdt: Select KERNFS when enabling INTEL_RDT_A x86/intel_rdt: Prevent deadlock against hotplug lock x86/intel_rdt: Protect info directory from removal x86/intel_rdt: Add info files to Documentation x86/intel_rdt: Export the minimum number of set mask bits in sysfs x86/intel_rdt: Propagate error in rdt_mount() properly x86/intel_rdt: Add a missing #include MAINTAINERS: Add maintainer for Intel RDT resource allocation x86/intel_rdt: Add scheduler hook x86/intel_rdt: Add schemata file x86/intel_rdt: Add tasks files x86/intel_rdt: Add cpus file x86/intel_rdt: Add mkdir to resctrl file system x86/intel_rdt: Add "info" files to resctrl file system ...

2016-12-20net: phy: use boolean dt properties for eee broken modesjbrunet1-3/+15
The patches regarding eee-broken-modes was merged before all people involved could find an agreement on the best way to move forward. While we agreed on having a DT property to mark particular modes as broken, the value used for eee-broken-modes mapped the phy register in very direct way. Because of this, the concern is that it could be used to implement configuration policies instead of describing a broken HW. In the end, having a boolean property for each mode seems to be preferred over one bit field value mapping the register (too) directly.

It's quite possible that a small region of the SRAM is reserved for all the mailbox communication and hence it may fail to request the region as it's already marked busy region.

2016-12-19mailbox: mailbox-test: add support for fasync/pollSudeep Holla1-8/+71
Currently the read operation on the message debug file returns error if there's no data ready to be read. It expects the userspace to retry if it fails. Since the mailbox response could be asynchronous, it would be good to add support to block the read until the data is available. We can also implement poll file operations so that the userspace can wait to become ready to perform any I/O. This patch implements the poll and fasync file operation callback for the test mailbox device.

2016-12-19mailbox: bcm-pdc: Convert from interrupts to poll for tx doneRob Rice1-62/+145
The PDC driver is a mailbox controller. A mailbox controller can report that a mailbox message has been "transmitted" either when a tx interrupt fires or by having the mailbox framework poll. This commit converts the PDC driver to the poll method. We found that the tx interrupt happens when the descriptors are read by the SPU hw. Thus, the interrupt method does not allow more than one tx message in the PDC tx DMA ring at a time. To keep the SPU hw busy, we would like to keep the tx ring full under heavy load. With the poll method, the PDC driver responds that the previous message has been transmitted if the tx ring has space for another message. SPU request messages take a variable number of descriptors. If 15 descriptors are available, there is a good chance another message will fit. Also increased the ring size from 128 to 512 descriptors. With this change, I found the PDC driver hangs on its spinlock under heavy load. The PDC spinlock is not required; so I removed it. Calls to pdc_send_data() are already synchronized because of the channel spinlock in the mailbox framework. Other references to ring indexes should not require locking because they only written on either the tx or rx side.

2016-12-19rtc: mcp795: fix month write resetting date to 1.Emil Bartczak1-5/+81
According to Microchip errata some combinations of date and month values may result in the date being reset to 1, even if the date is also written with the month (for example 31-07 or 31-08). As a workaround avoid writing date and month values within the same Write command. Instead, terminate the Write command after loading the date and begin a new command to write the month. In addition, disable the oscillator before loading the new values. This is done by ensuring both the ST and EXTOSC bits are cleared and waiting for the OSCON bit to clear.

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm updates from Dan Williams: "The libnvdimm pull request is relatively small this time around due to some development topics being deferred to 4.11. As for this pull request the bulk of it has been in -next for several releases leading to one late fix being added (commit 868f036fee4b ("libnvdimm: fix mishandled nvdimm_clear_poison() return value")). It has received a build success notification from the 0day-kbuild robot and passes the latest libnvdimm unit tests. Summary: - Dynamic label support: To date namespace label support has been limited to disambiguating cases where PMEM (direct load/store) and BLK (mmio aperture) accessed-capacity alias on the same DIMM. Since 4.9 added support for multiple namespaces per PMEM-region there is value to support namespace labels even in the non-aliasing case. The presence of a valid namespace index block force-enables label support when the kernel would otherwise rely on region boundaries, and permits the region to be sub-divided. - Handle media errors in namespace metadata: Complement the error handling for media errors in namespace data areas with support for clearing errors on writes, and downgrading potential machine-check exceptions to simple i/o errors on read. - Device-DAX region attributes: Add 'align', 'id', and 'size' as attributes for device-dax regions. In particular this enables userspace tooling to generically size memory mapping and i/o operations. Prevent userspace from growing assumptions / dependencies about the parent device topology for a dax region. A libnvdimm namespace may not always be the parent device of a dax region. - Various cleanups and small fixes" * tag 'libnvdimm-for-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: dax: add region 'id', 'size', and 'align' attributes libnvdimm: fix mishandled nvdimm_clear_poison() return value libnvdimm: replace mutex_is_locked() warnings with lockdep_assert_held libnvdimm, pfn: fix align attribute libnvdimm, e820: use module_platform_driver libnvdimm, namespace: use octal for permissions libnvdimm, namespace: avoid multiple sector calculations libnvdimm: remove else after return in nsio_rw_bytes() libnvdimm, namespace: fix the type of name variable libnvdimm: use consistent naming for request_mem_region() nvdimm: use the right length of "pmem" libnvdimm: check and clear poison before writing to pmem tools/testing/nvdimm: dynamic label support libnvdimm: allow a platform to force enable label support libnvdimm: use generic iostat interfaces
