From 39ee704e757268de833ffb956dda28f6aa2fa3a1 Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Thu, 31 May 2012 10:27:29 +0200 Subject: libblock: Add read-ahead task Read-ahead requests were previously executed in the context of the reading task. This blocks the reading task until the complete read with read-ahead transfer is finished. A read-ahead task is introduced to off-load the read-ahead transfer. This allows the reading task to work with the requested block more quickly. The read-ahead is triggered after two misses of ascending consecutive blocks or a read hit of a block read by the most-recent read-ahead transfer. The read-ahead feature is configurable and can be disabled. --- testsuites/libtests/block13/block13.doc | 11 +++++++++++ 1 file changed, 11 insertions(+) create mode 100644 testsuites/libtests/block13/block13.doc (limited to 'testsuites/libtests/block13/block13.doc') diff --git a/testsuites/libtests/block13/block13.doc b/testsuites/libtests/block13/block13.doc new file mode 100644 index 0000000000..04fc066ada --- /dev/null +++ b/testsuites/libtests/block13/block13.doc @@ -0,0 +1,11 @@ +This file describes the directives and concepts tested by this test set. + +test set name: block13 + +directives: + + TBD + +concepts: + + Tests the read-ahead feature of bdbuf. -- cgit v1.2.3
