2020-03-17ARM: dts: omap4-droid4: Fix lost touchscreen interruptsTony Lindgren
Looks like we can have the maxtouch touchscreen stop producing interrupts if an edge interrupt is lost. This can happen easily when the SoC idles as the gpio controller may not see any state for an edge interrupt if it is briefly triggered when the system is idle. Also it looks like maxtouch stops sending any further interrupts if the interrupt is not handled. And we do have several cases of maxtouch already configured with a level interrupt, so let's do that. With level interrupt the gpio controller has the interrupt state visible after idle. Note that eventually we will probably also be using the Linux generic wakeirq configured for the controller, but that cannot be done until the maxtouch driver supports runtime PM.

2020-03-13ARM: dts: dra7: Add bus_dma_limit for L3 busRoger Quadros
The L3 interconnect's memory map is from 0x0 to 0xffffffff. Out of this, System memory (SDRAM) can be accessed from 0x80000000 to 0xffffffff (2GB) DRA7 does support 4GB of SDRAM but upper 2GB can only be accessed by the MPU subsystem. Add the dma-ranges property to reflect the physical address limit of the L3 bus. Issues ere observed only with SATA on DRA7-EVM with 4GB RAM and CONFIG_ARM_LPAE enabled. This is because the controller supports 64-bit DMA and its driver sets the dma_mask to 64-bit thus resulting in DMA accesses beyond L3 limit of 2G. Setting the correct bus_dma_limit fixes the issue.

The IPU1 functional clock is the output of a mux clock (represented by ipu1_gfclk_mux previously) and the clock source for this has been updated to be sourced from dpll_core_h22x2_ck in commit 39879c7d963e ("ARM: dts: dra7xx-clocks: Source IPU1 functional clock from CORE DPLL"). ipu1_gfclk_mux is an obsolete clock now with the clkctrl conversion, and this clock source parenting is lost during the new clkctrl layout conversion. Remove this stale clock and fix up the clock source for this mux clock using the latest equivalent clkctrl clock. This restores the previous logic and ensures that the IPU1 continues to run at the same frequency of IPU2 and independent of the ABE DPLL.

git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/zonefs Pull new zonefs file system from Damien Le Moal: "Zonefs is a very simple file system exposing each zone of a zoned block device as a file. Unlike a regular file system with native zoned block device support (e.g. f2fs or the on-going btrfs effort), zonefs does not hide the sequential write constraint of zoned block devices to the user. As a result, zonefs is not a POSIX compliant file system. Its goal is to simplify the implementation of zoned block devices support in applications by replacing raw block device file accesses with a richer file based API, avoiding relying on direct block device file ioctls which may be more obscure to developers. One example of this approach is the implementation of LSM (log-structured merge) tree structures (such as used in RocksDB and LevelDB) on zoned block devices by allowing SSTables to be stored in a zone file similarly to a regular file system rather than as a range of sectors of a zoned device. The introduction of the higher level construct "one file is one zone" can help reducing the amount of changes needed in the application while at the same time allowing the use of zoned block devices with various programming languages other than C. Zonefs IO management implementation uses the new iomap generic code. Zonefs has been successfully tested using a functional test suite (available with zonefs userland format tool on github) and a prototype implementation of LevelDB on top of zonefs" * tag 'zonefs-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/zonefs: zonefs: Add documentation fs: New zonefs file system

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 fixes from Thomas Gleixner: "A set of fixes for X86: - Ensure that the PIT is set up when the local APIC is disable or configured in legacy mode. This is caused by an ordering issue introduced in the recent changes which skip PIT initialization when the TSC and APIC frequencies are already known. - Handle malformed SRAT tables during early ACPI parsing which caused an infinite loop anda boot hang. - Fix a long standing race in the affinity setting code which affects PCI devices with non-maskable MSI interrupts. The problem is caused by the non-atomic writes of the MSI address (destination APIC id) and data (vector) fields which the device uses to construct the MSI message. The non-atomic writes are mandated by PCI. If both fields change and the device raises an interrupt after writing address and before writing data, then the MSI block constructs a inconsistent message which causes interrupts to be lost and subsequent malfunction of the device. The fix is to redirect the interrupt to the new vector on the current CPU first and then switch it over to the new target CPU. This allows to observe an eventually raised interrupt in the transitional stage (old CPU, new vector) to be observed in the APIC IRR and retriggered on the new target CPU and the new vector. The potential spurious interrupts caused by this are harmless and can in the worst case expose a buggy driver (all handlers have to be able to deal with spurious interrupts as they can and do happen for various reasons). - Add the missing suspend/resume mechanism for the HYPERV hypercall page which prevents resume hibernation on HYPERV guests.

2020-02-08Fix up remaining devm_ioremap_nocache() in SGI IOC3 8250 UART driverLinus Torvalds
This is a merge error on my part - the driver was merged into mainline by commit c5951e7c8ee5 ("Merge tag 'mips_5.6' of git://../mips/linux") over a week ago, but nobody apparently noticed that it didn't actually build due to still having a reference to the devm_ioremap_nocache() function, removed a few days earlier through commit 6a1000bd2703 ("Merge tag 'ioremap-5.6' of git://../ioremap"). Apparently this didn't get any build testing anywhere. Not perhaps all that surprising: it's restricted to 64-bit MIPS only, and only with the new SGI_MFD_IOC3 support enabled. I only noticed because the ioremap conflicts in the ARM SoC driver update made me check there weren't any others hiding, and I found this one.

2020-02-08Merge branch 'pipe-exclusive-wakeup'Linus Torvalds
Merge thundering herd avoidance on pipe IO. This would have been applied for 5.5 already, but got delayed because of a user-space race condition in the GNU make jobserver code. Now that there's a new GNU make 4.3 release, and most distributions seem to have at least applied the (almost three year old) fix for the problem, let's see if people notice. And it might have been just bad random timing luck on my machine. If you do hit the race condition, things will still work, but the symptom is that you don't get nearly the expected parallelism when using "make -j<N>". The jobserver bug can definitely happen without this patch too, but seems to be easier to trigger when we no longer wake up pipe waiters unnecessarily. * pipe-exclusive-wakeup: pipe: use exclusive waits when reading or writing
2020-02-08pipe: use exclusive waits when reading or writingLinus Torvalds
This makes the pipe code use separate wait-queues and exclusive waiting for readers and writers, avoiding a nasty thundering herd problem when there are lots of readers waiting for data on a pipe (or, less commonly, lots of writers waiting for a pipe to have space). While this isn't a common occurrence in the traditional "use a pipe as a data transport" case, where you typically only have a single reader and a single writer process, there is one common special case: using a pipe as a source of "locking tokens" rather than for data communication. In particular, the GNU make jobserver code ends up using a pipe as a way to limit parallelism, where each job consumes a token by reading a byte from the jobserver pipe, and releases the token by writing a byte back to the pipe. This pattern is fairly traditional on Unix, and works very well, but will waste a lot of time waking up a lot of processes when only a single reader needs to be woken up when a writer releases a new token. A simplified test-case of just this pipe interaction is to create 64 processes, and then pass a single token around between them (this test-case also intentionally passes another token that gets ignored to test the "wake up next" logic too, in case anybody wonders about it): #include <unistd.h> int main(int argc, char **argv) { int fd[2], counters[2]; pipe(fd); counters[0] = 0; counters[1] = -1; write(fd[1], counters, sizeof(counters)); /* 64 processes */ fork(); fork(); fork(); fork(); fork(); fork(); do { int i; read(fd[0], &i, sizeof(i)); if (i < 0) continue; counters[0] = i+1; write(fd[1], counters, (1+(i & 1)) *sizeof(int)); } while (counters[0] < 1000000); return 0; } and in a perfect world, passing that token around should only cause one context switch per transfer, when the writer of a token causes a directed wakeup of just a single reader. But with the "writer wakes all readers" model we traditionally had, on my test box the above case causes more than an order of magnitude more scheduling: instead of the expected ~1M context switches, "perf stat" shows 231,852.37 msec task-clock # 15.857 CPUs utilized 11,250,961 context-switches # 0.049 M/sec 616,304 cpu-migrations # 0.003 M/sec 1,648 page-faults # 0.007 K/sec 1,097,903,998,514 cycles # 4.735 GHz 120,781,778,352 instructions # 0.11 insn per cycle 27,997,056,043 branches # 120.754 M/sec 283,581,233 branch-misses # 1.01% of all branches 14.621273891 seconds time elapsed 0.018243000 seconds user 3.611468000 seconds sys before this commit. After this commit, I get 5,229.55 msec task-clock # 3.072 CPUs utilized 1,212,233 context-switches # 0.232 M/sec 103,951 cpu-migrations # 0.020 M/sec 1,328 page-faults # 0.254 K/sec 21,307,456,166 cycles # 4.074 GHz 12,947,819,999 instructions # 0.61 insn per cycle 2,881,985,678 branches # 551.096 M/sec 64,267,015 branch-misses # 2.23% of all branches 1.702148350 seconds time elapsed 0.004868000 seconds user 0.110786000 seconds sys instead. Much better. [ Note! This kernel improvement seems to be very good at triggering a race condition in the make jobserver (in GNU make 4.2.1) for me. It's a long known bug that was fixed back in June 2017 by GNU make commit b552b0525198 ("[SV 51159] Use a non-blocking read with pselect to avoid hangs."). But there wasn't a new release of GNU make until 4.3 on Jan 19 2020, so a number of distributions may still have the buggy version. Some have backported the fix to their 4.2.1 release, though, and even without the fix it's quite timing-dependent whether the bug actually is hit. ] Josh Triplett says: "I've been hammering on your pipe fix patch (switching to exclusive wait queues) for a month or so, on several different systems, and I've run into no issues with it. The patch *substantially* improves parallel build times on large (~100 CPU) systems, both with parallel make and with other things that use make's pipe-based jobserver. All current distributions (including stable and long-term stable distributions) have versions of GNU make that no longer have the jobserver bug" Tested-by: Josh Triplett <josh@joshtriplett.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2020-02-08net: thunderx: use proper interface type for RGMIITim Harvey
The configuration of the OCTEONTX XCV_DLL_CTL register via xcv_init_hw() is such that the RGMII RX delay is bypassed leaving the RGMII TX delay enabled in the MAC: /* Configure DLL - enable or bypass * TX no bypass, RX bypass */ cfg = readq_relaxed(xcv->reg_base + XCV_DLL_CTL); cfg &= ~0xFF03; cfg |= CLKRX_BYP; writeq_relaxed(cfg, xcv->reg_base + XCV_DLL_CTL); This would coorespond to a interface type of PHY_INTERFACE_MODE_RGMII_RXID and not PHY_INTERFACE_MODE_RGMII. Fixing this allows RGMII PHY drivers to do the right thing (enable RX delay in the PHY) instead of erroneously enabling both delays in the PHY.
