The geni hardware has a FIFO that can hold up to 64 bytes (it has 16 entries that can hold 4 bytes each), at least on the two SoCs I tested (sdm845 and sc7180). We configured our RX Watermark to 0, which basically meant we got an interrupt as soon as the first 4 bytes showed up in the FIFO. Tracing the IRQ handler showed that we often only read 4 or 8 bytes per IRQ handler. I tried setting the RX Watermark to "fifo size - 2" but that just got me a bunch of overrun errors reported. Setting it to "fifo size - 3" seemed to work great, though. This made me worried that we'd start getting overruns if we had long interrupt latency, but that doesn't appear to be the case and delays inserted in the IRQ handler while using "fifo size - 3" didn't cause any errors. Presumably there is some interaction with the poorly-documented RFR (ready for receive) level means that "fifo size - 3" is the max. We are the SPI master, so it makes sense that there would be no problems with overruns, the master should just stop clocking. Despite "fifo size - 3" working, I chose "fifo size / 2" (8 entries = 32 bytes) which gives us a little extra time to get to the interrupt handler and should reduce dead time on the SPI wires. With this setting, I often saw the IRQ handler handle 40 bytes but sometimes up to 56 if we had bad interrupt latency. Testing by running "flashrom -p ec -r" on a Chromebook saw interrupts from the SPI driver cut roughly in half. Time was roughly the same.

If you added a bit of a delay (like a trace_printk) into the ISR for the spi-geni-qcom driver, you would suddenly start seeing some errors spit out. The problem was that, though the ISR itself held a lock, other parts of the driver didn't always grab the lock. One example race was this: CPU0 CPU1 ---- ---- spi_geni_set_cs() mas->cur_mcmd = CMD_CS; geni_se_setup_m_cmd(...) wait_for_completion_timeout(&xfer_done); <INTERRUPT> geni_spi_isr() complete(&xfer_done); <wakeup> pm_runtime_put(mas->dev); ... // back to SPI core spi_geni_transfer_one() setup_fifo_xfer() mas->cur_mcmd = CMD_XFER; mas->cur_cmd = CMD_NONE; // bad! return IRQ_HANDLED; Let's fix this. Before we start messing with hardware, we'll grab the lock to make sure that the IRQ handler from some previous command has really finished. We don't need to hold the lock unless we're in a state where more interrupts can come in, but we at least need to make sure the previous IRQ is done. This lock is used exclusively to prevent the IRQ handler and non-IRQ from stomping on each other. The SPI core handles all other mutual exclusion. As part of this, we change the way that the IRQ handler detects spurious interrupts. Previously we checked for our state variable being set to IRQ_NONE, but that was done outside the spinlock. We could move it into the spinlock, but instead let's just change it to look for the lack of any IRQ status bits being set. This can be done outside the lock--the hardware certainly isn't grabbing or looking at the spinlock when it updates its status register. It's possible that this will fix real (but very rare) errors seen in the field that look like: irq ...: nobody cared (try booting with the "irqpoll" option) NOTE: an alternate strategy considered here was to always make the complete() / spi_finalize_current_transfer() the very last thing in our IRQ handler. With such a change you could consider that we could be "lockless". In that case, though, we'd have to be very careful w/ memory barriers so we made sure we didn't have any bugs with weakly ordered memory. Using spinlocks makes the driver much easier to understand.

The driver locks its locks in two places. In the first usage of the lock the function doing the locking already has a sleeping call and thus we know we can't be called from interrupt context. That means we can use the "spin_lock_irq" variant of the function. In the second usage of the lock the function is the interrupt handler and we know interrupt handlers are called with interrupts disabled. That means we can use the "spin_lock" variant of the function. This patch is expected to be a no-op and is just a cleanup / slight optimization.

Set the appropriate flag such that the spi core will return -EINVAL on such transactions requested by chip drivers. This is an RFC as I need someone from Marvell/Cavium to confirm if this driver is used for other silicon that does support full duplex transfers (in which case we will need to identify that we are running on the ThunderX arch before setting the flag).

This reverts commit a43a67a2. This patch reverts the main part of switching direct io implementation to iomap infrastructure. There's a problem in invalidate page that couldn't be solved as regression in this development cycle. The problem occurs when buffered and direct io are mixed, and the ranges overlap. Although this is not recommended, filesystems implement measures or fallbacks to make it somehow work. In this case, fallback to buffered IO would be an option for btrfs (this already happens when direct io is done on compressed data), but the change would be needed in the iomap code, bringing new semantics to other filesystems. Another problem arises when again the buffered and direct ios are mixed, invalidation fails, then -EIO is set on the mapping and fsync will fail, though there's no real error. There have been discussions how to fix that, but revert seems to be the least intrusive option.

On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow unregistered mcast packets to pass.

Pull i2c updates from Wolfram Sang: "I2C has quite some patches for you this time. I hope it is the move to per-driver-maintainers which is now showing results. We will see. The big news is two new drivers (Nuvoton NPCM and Qualcomm CCI), larger refactoring of the Designware, Tegra, and PXA drivers, the Cadence driver supports being a slave now, and there is support to instanciate SPD eeproms for well-known cases (which will be user-visible because the i801 driver supports it), and some devm_platform_ioremap_resource() conversions which blow up the diffstat. Note that I applied the Nuvoton driver quite late, so some minor fixup patches arrived during the merge window. I chose to apply them right away because they were trivial" * 'i2c/for-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (109 commits) i2c: Drop stray comma in MODULE_AUTHOR statements i2c: npcm7xx: npcm_i2caddr[] can be static MAINTAINERS: npcm7xx: Add maintainer for Nuvoton NPCM BMC i2c: npcm7xx: Fix a couple of error codes in probe i2c: icy: Fix build with CONFIG_AMIGA_PCMCIA=n i2c: npcm7xx: Remove unnecessary parentheses i2c: npcm7xx: Add support for slave mode for Nuvoton i2c: npcm7xx: Add Nuvoton NPCM I2C controller driver dt-bindings: i2c: npcm7xx: add NPCM I2C controller i2c: pxa: don't error out if there's no pinctrl i2c: add 'single-master' property to generic bindings i2c: designware: Add Baikal-T1 System I2C support i2c: designware: Move reg-space remapping into a dedicated function i2c: designware: Retrieve quirk flags as early as possible i2c: designware: Convert driver to using regmap API i2c: designware: Discard Cherry Trail model flag i2c: designware: Add Baytrail sem config DW I2C platform dependency i2c: designware: slave: Set DW I2C core module dependency i2c: designware: Use `-y` to build multi-object modules dt-bindings: i2c: dw: Add Baikal-T1 SoC I2C controller ...

Pull more media updates from Mauro Carvalho Chehab: - a set of atomisp patches. They remove several abstraction layers, and fixes clang and gcc warnings (that were hidden via some macros that were disabling 4 or 5 types of warnings there).
