into clk-fixes
Pull Amlogic clk driver fixes from Jerome Brunet:
These are two simple fixes, yet the first one is quite important as it
solves boots hangs we've been having when FDIV2 gets disabled. This did
not show up before because this particular clock is heavily used and
only gets disabled for a very short period of time before modules (such
as ethernet or emmc) probe.
- fix boot issue with gxbb and gxl platforms
- fix racalculation error in the clk_audio_divider
* tag 'meson-clk-fixes-4.18-1' of https://github.com/BayLibre/clk-meson:
clk: meson: audio-divider is one based
clk: meson-gxbb: set fclk_div2 as CLK_IS_CRITICAL
|
|
On some systems, we come out of the bootloader with some
gates set with the clock "enabled" but the reset also
asserted.
Since 8a53fc511c5e "clk: aspeed: Prevent reset if clock is enabled"
we check that enabled bit in aspeed_clk_enabled(), and do
nothing if already set.
This breaks when the above scenario occurs, as the clock
is enabled, but the reset still needs to be lifted.
This patch fixes it by also checking the reset bit (if any)
and treating a gate in "reset" as being disabled.

Using a VMA on more than one timeline concurrently is the exception
rather than the rule (using it concurrently on multiple engines). As we
expect to only use one active tracker, store the most recently used
tracker inside the i915_vma itself and only fallback to the rbtree if
we need a second or more concurrent active trackers.
v2: Comments on how we overwrite any existing last_active cache.
v3: __list_del_entry() before list_replace_init() is confusing and, much
more important, entirely redundant.
v4: Note that both last_active and the rbtree may be simultaneously
tracking this timeline, albeit with different requests, and so the vma
may be retired twice for the same timeline.
v5: No, that list_del is required!

In the next patch, we will want to be able to use more flexible request
timelines that can hop between engines. From the vma pov, we can then
not rely on the binding of this request to an engine and so can not
ensure that different requests are ordered through a per-engine
timeline, and so we must track activity of all timelines. (We track
activity on the vma itself to prevent unbinding from HW before the HW
has finished accessing it.)
v2: Switch to a rbtree for 32b safety (since using u64 as a radixtree
index is fraught with aliasing of unsigned longs).

Handling such a late error in request construction is tricky, but to
accommodate future patches which may allocate here, we potentially could
err. To handle the error after already adjusting global state to track
the new request, we must finish and submit the request. But we don't
want to use the request as not everything is being tracked by it, so we
opt to cancel the commands inside the request.

(via kernel_read()/kernel_write(), which can e.g. be triggered via

If the GPU is irrecoverably wedged, we can not execute any requests
making testing execlists (request execution) pointless. Skip!

If the HW (or driver) doesn't support logical contexts, don't pretend we
gain anything from trying to execute GPU commands with them. At best it
reports -ENODEV, which is an unhelpful failure that we should just skip.
v2: Be more specific and check the driver/engine caps for logical (HW)
context support.

Avoid looking at the magical engines[RCS] to decide if the HW and driver
supports logical contexts, and instead record that knowledge during
initialisation.

The comment is the same as in the top-level Makefile.
Also, the comments contain typos:
- the .PHONY variable -> the PHONY variable
- se we can ... -> so we can ...
Instead of fixing the typos, just remove the duplicated comments.

The comment line for addtree says "skip if -I has no parameter".
What it actually does is "drop if -I has no parameter". For example,
if you have the compiler flag '-I foo' (a space between), it will be
converted to 'foo'. This completely changes the meaning.
What we want is, "do nothing" for -I without parameter so that
'-I foo' is kept as-is.

Update Documentation/kbuild/kconfig.txt, which mostly contains
user help for using the kernel config tools.
- Add mention of 'nconfig' embedded help text.
- Make the section on new config symbols readable.
- Correct how to find menuconfig search help.
- Add section on 'nconfig' usage.
- Mention that gconfig has multiple viewing modes/options.

Removed Kbuild documentation for INSTALL_FW_PATH.
The kbuild symbol INSTALL_FW_PATH was removed from Kbuild tools in
September 2017 (for 4.14) but the symbol was not deleted from
the kbuild documentation, so do that now.

Just using "sparc" produces a 64-bit config file.

We can simplify the encoder's get_power_domains() hook by calling it
only if the encoder is active. That way the hook can return its power
domains unconditionally without checking the active state by calling
encoder::get_hw_state(). This get_hw_state() query is in fact
redundant since it's already done by intel_modeset_readout_hw_state()
setting the encoder's crtc or leaving it NULL accordingly. Let's use
this fact to decide if the encoder is active.
While at it clarify the comment in intel_ddi_get_power_domains() about
primary vs. fake MST encoders and make sure we never do an incorrect
encoder->dig_port cast for fake MST encoders.
