[Why]
Plane scaling parameters are not correctly filled or updated when
performing fast updates.
They're filled when creating the dc plane state and during atomic check.
While the atomic check code path happens for the plane even during fast
updates, the issue is that they're done in place on the dc_plane_state
directly. This dc_plane_state may be the current state plane state
being used by the hardware, so these parameters won't be correctly
programmed.
The new scaling parameters should instead be passed as an update
to the plane.
[How]
Update fill_rects_from_plane_state to not modify dc_plane_state
directly. Update the call sites that use this to fill in the appropriate
values.

Unlike external DP panels, internal eDP does not perform
verify link caps because the panel connection is fixed.
So if GOP enabled the eDP at boot, we can retain its

[why]

[Why]
Hardware can support video surfaces and DC tells us which planes are
suitable via DC plane caps.
[How]
The supported formats array will now vary based on what DC tells us,
so create an array and fill it dynamically based on plane types and

Ideally we'd query support for every format via DC plane caps, but for

[Why]
Some LED Driver might not like Fractional PWM especially at extreme
ranges near 0% or 100%.

We want a way to switch fractional PWM on/off either for debug, or

Add DC code that can send new FW command to enable/disable
fractional PWM.

Merge page ref overflow branch.
Jann Horn reported that he can overflow the page ref count with
sufficient memory (and a filesystem that is intentionally extremely
slow).
Admittedly it's not exactly easy. To have more than four billion
references to a page requires a minimum of 32GB of kernel memory just
for the pointers to the pages, much less any metadata to keep track of
those pointers. Jann needed a total of 140GB of memory and a specially
crafted filesystem that leaves all reads pending (in order to not ever
free the page references and just keep adding more).
Still, we have a fairly straightforward way to limit the two obvious
user-controllable sources of page references: direct-IO like page
references gotten through get_user_pages(), and the splice pipe page
duplication. So let's just do that.
* branch page-refs:
fs: prevent page refcount overflow in pipe_buf_get
mm: prevent get_user_pages() from overflowing page refcount
mm: add 'try_get_page()' helper function
mm: make page ref count overflow check tighter and more explicit
|
|
Change pipe_buf_get() to return a bool indicating whether it succeeded
in raising the refcount of the page (if the thing in the pipe is a page).
This removes another mechanism for overflowing the page refcount. All
callers converted to handle a failure.

If the page refcount wraps around past zero, it will be freed while
there are still four billion references to it. One of the possible
avenues for an attacker to try to make this happen is by doing direct IO
on a page multiple times. This patch makes get_user_pages() refuse to
take a new page reference if there are already more than two billion
references to the page.

This is the same as the traditional 'get_page()' function, but instead
of unconditionally incrementing the reference count of the page, it only
does so if the count was "safe". It returns whether the reference count
was incremented (and is marked __must_check, since the caller obviously
has to be aware of it).
Also like 'get_page()', you can't use this function unless you already
had a reference to the page. The intent is that you can use this
exactly like get_page(), but in situations where you want to limit the
maximum reference count.
The code currently does an unconditional WARN_ON_ONCE() if we ever hit
the reference count issues (either zero or negative), as a notification
that the conditional non-increment actually happened.
NOTE! The count access for the "safety" check is inherently racy, but
that doesn't matter since the buffer we use is basically half the range
of the reference count (ie we look at the sign of the count).

We have a VM_BUG_ON() to check that the page reference count doesn't
underflow (or get close to overflow) by checking the sign of the count.
That's all fine, but we actually want to allow people to use a "get page
ref unless it's already very high" helper function, and we want that one
to use the sign of the page ref (without triggering this VM_BUG_ON).
Change the VM_BUG_ON to only check for small underflows (or _very_ close
to overflowing), and ignore overflows which have strayed into negative
territory.

Add support for 2MB sized pages. This will improve our map and unmap
times and save a bit of memory by avoiding 3rd level page tables for
contiguous allocations.
As we use shmem for buffers and huge page allocations for shmem are off
by default, there isn't an improvement out of the box and userspace must
enable THP for shmem.
It's not clear if the h/w can support 1GB page sizes which standard
ARM long format descriptors support. In any case, it is unlikely we'll
see any contiguous 1GB allocations on current h/w.

ARM Mali midgard GPU is similar to standard 64-bit stage 1 page tables, but
have a few differences. Add a new format type to represent the format. The
input address size is 48-bits and the output address size is 40-bits (and
possibly less?). Note that the later bifrost GPUs follow the standard
64-bit stage 1 format.
The differences in the format compared to 64-bit stage 1 format are:
The 3rd level page entry bits are 0x1 instead of 0x3 for page entries.
The access flags are not read-only and unprivileged, but read and write.
This is similar to stage 2 entries, but the memory attributes field matches
stage 1 being an index.
The nG bit is not set by the vendor driver. This one didn't seem to matter,
but we'll keep it aligned to the vendor driver.

Pull sound fixes from Takashi Iwai:
"Well, this one became unpleasantly larger than previous pull requests,
but it's a kind of usual pattern: now it contains a collection of ASoC
fixes, and nothing to worry too much.
The fixes for ASoC core (DAPM, DPCM, topology) are all small and just
covering corner cases. The rest changes are driver-specific, many of
which are for x86 platforms and new drivers like STM32, in addition to
the usual fixups for HD-audio"
