Subject: [PATCH 1/2] mm/ptdump: Split note_page() into level specific callbacks
Date: Mon, 17 Mar 2025 11:48:17 +0530 [thread overview]
Message-ID: <20250317061818.16244-2-anshuman.khandual@arm.com> (raw)
In-Reply-To: <20250317061818.16244-1-anshuman.khandual@arm.com>
Last argument passed down in note_page() is u64 assuming pxd_val() returned
value (all page table levels) is 64 bit - which might not be the case going
ahead when D128 page tables is enabled on arm64 platform. Besides pxd_val()
is very platform specific and its type should not be assumed in generic MM.
Split note_page() into individual page table level specific callbacks which
accepts corresponding pxd_t argument instead and then subscribing platforms
just derive pxd_val() from the entries as required and proceed as earlier.
Also add a note_page_flush() callback for flushing the last page table page
that was being handled earlier via level = -1.
