Register the MDT segments, custom dumpfn and private data with the remoteproc core dump functionality. Signed-off-by: Sibi Sankar <sibis@codeaurora.org> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2018-10-19remoteproc: qcom: q6v5-mss: Add custom dump function for modemSibi Sankar
The per segment dump function is responsible for loading the mba before device memory segments associated with coredump can be populated and for cleaning up the resources post coredump. Signed-off-by: Sibi Sankar <sibis@codeaurora.org> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2018-10-19remoteproc: qcom: q6v5-mss: Refactor mba load/unload sequenceSibi Sankar
Refactor re-useable parts of mba load/unload sequence into mba_load and mba_reclaim respectively. This is done in order to prevent code duplication for modem coredump, which requires the mba to be loaded before dumping the segments. The following changes in functionality are intended: * Add software bypass to avoid high MX current in mpss error path. * Remove the proxy votes of clk/regs only after the active/reset clks/regs. * Reclaim MBA memory after mpss_load failure in mba_reclaim func. * Set/Unset the dump_mba_loaded flag on mba_load/mba_reclaim respectively.

2018-10-19platform/x86: intel_telemetry: report debugfs failureRajneesh Bhardwaj
On some Goldmont based systems such as ASRock J3455M the BIOS may not enable the IPC1 device that provides access to the PMC and PUNIT. In such scenarios, the IOSS and PSS resources from the platform device can not be obtained and result in a invalid telemetry_plt_config which is an internal data structure that holds platform config and is maintained by the telemetry platform driver. This is also applicable to the platforms where the BIOS supports IPC1 device under debug configurations but IPC1 is disabled by user or the policy. This change allows user to know the reason for not seeing entries under /sys/kernel/debug/telemetry/* when there is no apparent failure at boot.

2018-10-19genirq: Fix race on spurious interrupt detectionLukas Wunner
Commit 1e77d0a1ed74 ("genirq: Sanitize spurious interrupt detection of threaded irqs") made detection of spurious interrupts work for threaded handlers by: a) incrementing a counter every time the thread returns IRQ_HANDLED, and b) checking whether that counter has increased every time the thread is woken. However for oneshot interrupts, the commit unmasks the interrupt before incrementing the counter. If another interrupt occurs right after unmasking but before the counter is incremented, that interrupt is incorrectly considered spurious: time | irq_thread() | irq_thread_fn() | action->thread_fn() | irq_finalize_oneshot() | unmask_threaded_irq() /* interrupt is unmasked */ | | /* interrupt fires, incorrectly deemed spurious */ | | atomic_inc(&desc->threads_handled); /* counter is incremented */ v This is observed with a hi3110 CAN controller receiving data at high volume (from a separate machine sending with "cangen -g 0 -i -x"): The controller signals a huge number of interrupts (hundreds of millions per day) and every second there are about a dozen which are deemed spurious. In theory with high CPU load and the presence of higher priority tasks, the number of incorrectly detected spurious interrupts might increase beyond the 99,900 threshold and cause disablement of the interrupt. In practice it just increments the spurious interrupt count. But that can cause people to waste time investigating it over and over. Fix it by moving the accounting before the invocation of irq_finalize_oneshot().

2018-10-19arm64: KVM: Guests can skip __install_bp_hardening_cb()s HYP workJames Morse
enable_smccc_arch_workaround_1() passes NULL as the hyp_vecs start and end if the HVC conduit is in use, and ARM_SMCCC_ARCH_WORKAROUND_1 is detected. If the guest kernel happened to be built with KVM_INDIRECT_VECTORS, we go on to allocate a slot, memcpy() the empty workaround in and do the appropriate cache maintenance. This works as we always tell memcpy() the range is 0, so it never accesses the NULL src pointer, but we still do the cache maintenance. If hyp_vecs_start is NULL we know we're a guest, just update the fn like the !KVM_INDIRECT_VECTORS version.

2018-10-19x86/intel_rdt: Prevent pseudo-locking from using stale pointersJithu Joseph
When the last CPU in an rdt_domain goes offline, its rdt_domain struct gets freed. Current pseudo-locking code is unaware of this scenario and tries to dereference the freed structure in a few places. Add checks to prevent pseudo-locking code from doing this. While further work is needed to seamlessly restore resource groups (not just pseudo-locking) to their configuration when the domain is brought back online, the immediate issue of invalid pointers is addressed here.

2018-10-19fs: group frequently accessed fields of struct super_block togetherAmir Goldstein
Kernel test robot reported [1] a 6% performance regression in a concurrent unlink(2) workload on commit 60f7ed8c7c4d ("fsnotify: send path type events to group with super block marks"). The performance test was run with no fsnotify marks at all on the data set, so the only extra instructions added by the offending commit are tests of the super_block fields s_fsnotify_{marks,mask} and these tests happen on almost every single inode access. When adding those fields to the super_block struct, we did not give much thought of placing them on a hot cache lines (we just placed them at the end of the struct). Re-organize struct super_block to try and keep some frequently accessed fields on the same cache line. Move the frequently accessed fields s_fsnotify_{marks,mask} near the frequently accessed fields s_fs_info,s_time_gran, while filling a 64bit alignment hole after s_time_gran. Move the seldom accessed fields s_id,s_uuid,s_max_links,s_mode near the seldom accessed fields s_vfs_rename_mutex,s_subtype. Rong Chen confirmed that this patch solved the reported problem.

2018-10-19spi: omap2-mcspi: Set FIFO DMA trigger level to word lengthVignesh R
McSPI has 32 byte FIFO in Transmit-Receive mode. Current code tries to configuration FIFO watermark level for DMA trigger to be GCD of transfer length and max FIFO size which would mean trigger level may be set to 32 for transmit-receive mode if length is aligned. This does not work in case of SPI slave mode where FIFO always needs to have data ready whenever master starts the clock. With DMA trigger size of 32 there will be a small window during slave TX where DMA is still putting data into FIFO but master would have started clock for next byte, resulting in shifting out of stale data. Similarly, on Slave RX side there may be RX FIFO overflow Fix this by setting FIFO watermark for DMA trigger to word length. This means DMA is triggered as soon as FIFO has space for word length bytes and DMA would make sure FIFO is almost always full therefore improving FIFO occupancy in both master and slave mode.

The wm_adsp_buffer struct is the control header of a circular buffer used to transfer data from the firmware over the control interface to an ALSA compressed stream. The original names of the fields pointing to the data buffer were based on ADSP2V2 memory layout where they correspond to {XM, XM, YM}. But this circular buffer could be used on other types of DSP core that have different memory region types. Also the names and description of the size fields were not very clear. The field names and descriptions have been changed to be generic and not imply any particular memory types. This patch updates the wm_adsp driver to the new field names.
