Subject: Re: [PATCH v10 09/11] x86/virt/tdx: Enable Dynamic PAMT
Date: Thu, 3 Sep 2026 08:38:36 -0700	[thread overview]
Message-ID: <9adb11c7-7e8f-4a6c-a4d6-fdcb717c41f5@intel.com> (raw)
In-Reply-To: <20260903015113.93343-10-rick.p.edgecombe@intel.com>

This patch is doing too much.

Let's just replace it with a patch that enables DPAMT when it's
supported by the module. I can apply that.

Then, we can talk about how a disable command-line knob would work.
