Subject: [RESEND] CXL_MEM_QUERY_COMMANDS returning commands not supported by the hardware.
Date: Mon, 10 Oct 2022 13:59:25 +0100	[thread overview]
Message-ID: <20221010135925.00006e75@huawei.com> (raw)


Resent because I can't type email addresses so this didn't got to the list..

Hi All,

Noticed, whilst implementing a switch CCI mailbox version of the same...

UAPI documentation include/uapi/linux/cxl_mem.h says:

struct cxl_mem_query_commands...

Allow userspace to query the available commands supported by both the
driver, and the hardware.

Currently it seem to report all commands without checking they are in the CEL.

Easy to tell given I just added a bunch of switch commands which are
apparently supported by the type 3 devices (which would be novel).

How to fix?  Make the code do what the docs suggest, or change the
docs?

Or am I missing something?

Thanks,

Jonathan
