Subject: [PATCH AUTOSEL 5.8 03/53] MIPS: Loongson64: Do not override watch and ejtag feature
Date: Mon, 7 Sep 2020 12:31:29 -0400 [thread overview]
Message-ID: <20200907163220.1280412-3-sashal@kernel.org> (raw)
In-Reply-To: <20200907163220.1280412-1-sashal@kernel.org>
From: Jiaxun Yang <jiaxun.yang@flygoat.com>
[ Upstream commit 433c1ca0d441ee0b88fdd83c84ee6d6d43080dcd ]
Do not override ejtag feature to 0 as Loongson 3A1000+ do have ejtag.
For watch, as KVM emulated CPU doesn't have watch feature, we should
not enable it unconditionally.
