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
