Subject: Re: [PATCH v12 2/5] fs/proc/task_mmu: Implement IOCTL to get and optionally clear info about PTEs
Date: Tue, 13 Jun 2023 15:35:44 +0500 [thread overview]
Message-ID: <0e6b318a-bbf8-3701-00af-1802c6347897@collabora.com> (raw)
In-Reply-To: <9d8b5b8e-47c9-16dd-050a-45d917d73c07@collabora.com>
Hi Vineet,
It seems arc architecture supports CONFIG_TRANSPARENT_HUGEPAGE, but it
doesn't define HPAGE_SIZE. It only defines PAGE_SIZE in
include/uapi/asm/page.h? AFAIK HPAGE_SIZE must be defined when
CONFIG_TRANSPARENT_HUGEPAGE is enabled. What can be the solution here for arc?
Should I just compile out this code for arc architecture specifically?
Thanks,
Usama
