Subject: [RFC 0/5] ARC: handle DSP presence in HW
Date: Fri, 27 Dec 2019 21:03:42 +0300	[thread overview]
Message-ID: <20191227180347.3579-1-Eugeniy.Paltsev@synopsys.com> (raw)

Arc processors may have DSP extension which is optional.
In this patch series we:
* Handle issues caused by DSP extension presence in HW
* Add optional support for DSP-enabled applications in
  userspace (with optional AGU extension support)
* Do minor cleanups

Eugeniy Paltsev (5):
  ARC: pt_regs: remove hardcoded registers offset
  ARC: add helpers to sanitize config options
  ARC: handle DSP presence in HW
  ARC: add support for DSP-enabled userspace applications
  ARC: allow userspace DSP applications to use AGU extensions
