Subject: [PATCHSET #upstream] libata: modularize PMP support, take #1
Date: Tue, 25 Mar 2008 22:25:14 +0900 [thread overview]
Message-ID: <1206451517133-git-send-email-htejun@gmail.com> (raw)
Hello, all.
This patchset modularizes PMP support and contains the following three
patches.
mails/0001-libata-separate-PMP-support-code-from-core-code.patch
mails/0002-libata-implement-PMP-helpers.patch
mails/0003-libata-make-PMP-support-optional.patch
LLDs which support PMP don't depend on PMP. If PMP is turned on,
those LLDs support PMP, if PMP is off, they don't. The size of
libata.ko on x86_64 w all debugging options off change like the
following.
ON-DISK LOADED
+SFF+PMP 226k 157k
+SFF-PMP 204k 141k
-SFF+PMP 193k 133k
-SFF-PMP 171k 117k
Both ahci and sata_sil24 have been verified to work w/ PMP turned on
and off.
This patchset is on top of
upstream-fixes (4cde32fc4b32e96a99063af3183acdfd54c563f0)
