Between when we load the DSP and when it actually starts running put the core into a lower power state where the memory is retained but nothing is clocked. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@kernel.org>

Replace the 1ms msleep in wm_adsp2_ena with a usleep_range, as per normal guidance on delay functions. Also tighten up the delay a little as 1ms was quite generous. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@kernel.org>

Currently the DSP loading is split into two widgets, the preloader that is a snd_soc_dapm_dai_link widget which starts a thread to download the firmware, and the DSP itself which is a snd_soc_dapm_out_drv and synchronises the thread back in to the DAPM sequence. This allows the firmware download to be overlapped with the rest of the path bring up. The use of a snd_soc_dapm_dai_link widget requires the preloader to be part of the audio path in DAPM, really a supply widget is a better fit for the preloader. The preloader is something that needs to be done for the DSP to function, not a part of the audio path itself. This change makes the DSP preloader widget a supply widget, which as well as probably being a better fit will also make it much simpler to power up the preloader widget to trigger firmware download to the core independently of the audio path coming up.

Currently SYSCLK is attached to every compressed DAI as this follows the pattern of attaching clocks to the chips inputs and outputs, however, it is really the DSP that requires the clock here. As firmware download can be a significant part of the path startup time for these devices occasionally it would be desirable to download the firmware in advance of the path being brought up. To help facilitate this early firmware loading this patch attaches the SYSCLK to the DSP preloader widget. This also saves us adding a new route to SYSCLK every time a new compressed DAI is created.

As part of the work to download firmware before the audio path is brought up the DSP will be put into a low power state between downloading firmware to the core and starting it running. This will mean that the firmware ALSA controls are not accessible in the hardware during this period of time. To prepare for this change we gate access to the hardware in the ALSA control handlers on the DSP being running rather than simply booted and move the synchronisation of the control caches out of the preloader delayed work and into the main DAPM thread after the DSP will have been brought out of its low power state.

Currently the wm_adsp driver has a flag that indicates the DSP is "running", this flag is used to gate access to the hardware. However this flag is actually set in the firmware download thread after the firmware has been downloaded, but this is before the core is actually started running, so really it currently indicates that the core has been booted and is perhaps running. This patch clearly separates out the concepts of booted (firmware is downloaded) and running (code is executing on the DSP) within the wm_adsp driver.

For best performance changing the synchroniser state whilst the FLL is running should be avoided. As this has been done fairly regularly in practice rather than hard preventing this, simply improve the FLL enable sequence and give a warning if the user changes the synchroniser state.

ASoC: Fixes for v4.8 A clutch of fixes for v4.8. These are mainly driver specific, the most notable ones being those for OMAP which fix a series of issues that broke boot on some platforms there when deferred probe kicked in. There's also one core fix for an issue when unbinding a card which for some reason had managed to not manifest until recently.

This is an entirely new driver instead of yet another set of patches to sb_edac.c because: 1) Mapping from PCI devices to socket/memory controller is significantly different. Skylake scatters devices on a socket across a number of PCI buses. 2) There is an extra level of interleaving via the "mcroute" register that would be a little messy to squeeze into the old driver. 3) Validation is getting too expensive. Changes to sb_edac need to be checked against Sandy Bridge, Ivy Bridge, Haswell, Broadwell and Knights Landing.

Helge Deller authored
When building gccgo in userspace, errno.h gets parsed and the go include file sysinfo.go is generated. Since EREFUSED is defined to the same value as ECONNREFUSED, and ECONNREFUSED is defined later on in errno.h, this leads to go complaining that EREFUSED isn't defined yet. Fix this trivial problem by moving the define of EREFUSED down after ECONNREFUSED in errno.h (and clean up the indenting while touching this line).

The kernel test robot reported a usercopy failure in the new hardened sanity checks, due to a page-crossing copy of the FPU state into the task structure. This happened because the kernel test robot was testing with SLOB, which doesn't actually do the required book-keeping for slab allocations, and as a result the hardening code didn't realize that the task struct allocation was one single allocation - and the sanity checks fail. Since SLOB doesn't even claim to support hardening (and you really shouldn't use it), the straightforward solution is to just make the usercopy hardening code depend on the allocator supporting it.
