Subject: Re: [PATCH net-next v8 01/15] ibmveth: Add MQ RX hypercall wrappers and call definitions
Date: Tue, 10 Nov 2026 23:57:45 +0000 [thread overview]
Message-ID: <sashiko-outbox-207971@kernel.org> (raw)
In-Reply-To: <20261109235556.60604-2-mmc@linux.ibm.com>
> Single-queue ibmveth only needs h_register_logical_lan() plus legacy
> buffer add/free calls. MQ RX uses per-queue handles, so the driver must
> also be able to register/deregister subordinate queues and post
> buffers against a specific queue handle.

> Add the PHYP call IDs for:
>
> H_REG_LOGICAL_LAN_QUEUE (0x49C)
> H_ADD_LOGICAL_LAN_BUFFERS_QUEUE (0x4A0)
> H_FREE_LOGICAL_LAN_QUEUE (0x4A8)
>
> as defined in PAPR 11.20.00. The gaps at 0x498 (reserved) and 0x4A4
> (reserved for H_FREE_LOGICAL_LAN_BUFFER_QUEUE) are intentional; this
> series tears queues down with H_FREE_LOGICAL_LAN_QUEUE and does not add
