staging: prefix header search paths with $(srctree)/

2019-02-04T11:30:27+00:00

Currently, the Kbuild core manipulates header search paths in a crazy
way [1].

To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.

Having whitespaces after -I does not matter since commit 48f6e3cf5bc6
("kbuild: do not drop -I without parameter").

staging: vchiq: Fix local event signalling

2019-01-15T15:31:09+00:00

Prior to the recent event reworking (see Fixes), thread synchronisation
was implemented using completions, the worker thread being woken with
a call to complete(). The replacement uses waitqueues, which are more
like condition variables in that the waiting thread is only woken if
the condition is true.

When the VPU signals the ARM, it first sets the event's fired flag to
indicate which event is being signalled, but the places in the
ARM-side code where the worker thread is being woken -
remote_event_signal_local via request_poll - did not do so as it
wasn't previously necessary, and since the armed flag was being
cleared this lead to a deadlock.

cross-tree: phase out dma_zalloc_coherent()

2019-01-08T12:58:37+00:00

We already need to zero out memory for dma_alloc_coherent(), as such
using dma_zalloc_coherent() is superflous. Phase it out.

This change was generated with the following Coccinelle SmPL patch:

@ replace_dma_zalloc_coherent @
expression dev, size, data, handle, flags;
@@

-dma_zalloc_coherent(dev, size, handle, flags)
+dma_alloc_coherent(dev, size, handle, flags)
