Subject: [PATCH v0 1/1] common/cnxk: fix DPI mailbox structure
Date: Wed, 15 Jan 2025 18:06:54 +0530 [thread overview]
Message-ID: <20250115123654.1490937-1-vattunuru@marvell.com> (raw)
From: Vamsi Attunuru <vattunuru@marvell.com>
In the existing DPI mailbox structure, one of the fields
spans a 64-bit boundary, making it appear unusual and
complicatng extraction using bit operations.
Patch enlarges csize fields to ensure that mailbox fields
are correctly positioned.
Fixes: b6e395692b6d ("common/cnxk: add DPI DMA support")
