2017-11-30hwmon: (jc42) optionally try to disable the SMBUS timeoutPeter Rosin
With a nxp,se97 chip on an atmel sama5d31 board, the I2C adapter driver is not always capable of avoiding the 25-35 ms timeout as specified by the SMBUS protocol. This may cause silent corruption of the last bit of any transfer, e.g. a one is read instead of a zero if the sensor chip times out. This also affects the eeprom half of the nxp-se97 chip, where this silent corruption was originally noticed. Other I2C adapters probably suffer similar issues, e.g. bit-banging comes to mind as risky... The SMBUS register in the nxp chip is not a standard Jedec register, but it is not special to the nxp chips either, at least the atmel chips have the same mechanism. Therefore, do not special case this on the manufacturer, it is opt-in via the device property anyway.

2017-11-30RISC-V: Allow userspace to flush the instruction cacheAndrew Waterman
Despite RISC-V having a direct 'fence.i' instruction available to userspace (which we can't trap!), that's not actually viable when running on Linux because the kernel might schedule a process on another hart. There is no way for userspace to handle this without invoking the kernel (as it doesn't know the thread->hart mappings), so we've defined a RISC-V specific system call to flush the instruction cache. This patch adds both a system call and a VDSO entry. If possible, we'd like to avoid having the system call be considered part of the user-facing ABI and instead restrict that to the VDSO entry -- both just in general to avoid having additional user-visible ABI to maintain, and because we'd prefer that users just call the VDSO entry because there might be a better way to do this in the future (ie, one that doesn't require entering the kernel).

2017-11-30RISC-V: Flush I$ when making a dirty page executableAndrew Waterman
The RISC-V ISA allows for instruction caches that are not coherent WRT stores, even on a single hart. As a result, we need to explicitly flush the instruction cache whenever marking a dirty page as executable in order to preserve the correct system behavior. Local instruction caches aren't that scary (our implementations actually flush the cache, but RISC-V is defined to allow higher-performance implementations to exist), but RISC-V defines no way to perform an instruction cache shootdown. When explicitly asked to do so we can shoot down remote instruction caches via an IPI, but this is a bit on the slow side. Instead of requiring an IPI to all harts whenever marking a page as executable, we simply flush the currently running harts. In order to maintain correct behavior, we additionally mark every other hart as needing a deferred instruction cache which will be taken before anything runs on it.

2017-11-30drm/i915: Avoid PPS HW/SW state mismatch due to roundingImre Deak
We store a SW state of the t11_t12 timing in 100usec units but have to program it in 100msec as required by HW. The rounding used during programming means there will be a mismatch between the SW and HW states of this value triggering a "PPS state mismatch" error. Avoid this by storing the already rounded-up value in the SW state. Note that we still calculate panel_power_cycle_delay with the finer 100usec granularity to avoid any needless waits using that version of the delay.

The SoC match entries were incorrect, they should have matched on the machine name instead of the SoC family. Fix it. The result was observed on OpenPandora with OMAP3530 where the panel only had the Blue channel and Red&Green were missing. It was not observed on GTA04 with DM3730.

2017-11-30omapdrm: hdmi4: Correct the SoC revision matchingPeter Ujfalusi
I believe the intention of the commit 2c9fc9bf45f8 ("drm: omapdrm: Move FEAT_HDMI_* features to hdmi4 driver") was to identify omap4430 ES1.x, omap4430 ES2.x and other OMAP4 revisions, like omap4460. By using family=OMAP4 in the match the code will treat omap4460 ES1.x in a same way as it would treat omap4430 ES1.x This breaks HDMI audio on OMAP4460 devices (PandaES for example). Correct the match rule so we are not going to get false positive match.

The new backlight code causes a link failure when backlight support itself is disabled: drivers/gpu/drm/omapdrm/displays/panel-dpi.o: In function `panel_dpi_probe_of': panel-dpi.c:(.text+0x35c): undefined reference to `of_find_backlight_by_node' This adds a Kconfig dependency like we have for the other OMAP display targets.

2017-11-30drm/i915: Disable THP until we have a GPU read BW W/AJoonas Lahtinen
We seem to be missing some W/A for 2M pages and are getting a hit on raw GPU read bandwidths (even 30%) even though the GPU write bandwidths improve (even 10%). For now, disable THP, which is our only practical source of 2M pages until we have a W/A for the issue. v2: - Be explicit that we talk about GPU bandwidths (Eero) - s/deny/never/ because that's why (Chris) Reported-by: Valtteri Rantala <valtteri.rantala@intel.com> Fixes: b901bb89324a ("drm/i915/gemfs: enable THP") Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Matthew Auld <matthew.auld@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Valtteri Rantala <valtteri.rantala@intel.com> Cc: Eero Tamminen <eero.t.tamminen@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Matthew Auld <matthew.auld@intel.com> Tested-by: Valtteri Rantala <valtteri.rantala@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20171127091233.7001-1-joonas.lahtinen@linux.intel.com (cherry picked from commit 9987da4b5dcfc8b94b702d4bb94b30955eb73c75) Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>
