Subject: What is the maximum size in ramdisk_size boot parameter?
Date: Tue, 07 Sep 2004 21:05:39 +0900 [thread overview]
Message-ID: <chk86k$smh$1@sea.gmane.org> (raw)
Hello,
I am trying to boot my laptop via PXE and I still am in the middle of nowhere...
So, while trying to cram more and more stuff on a ramdisk, I started seeing "strange behaviour" and this got me thinking, is there a limit to ramdisk_size boot parameter??
Looking at drivers/block/rd.c (on 2.6.8.1) I couldn't find anything like that...
So is there any intrinsic upper limit, apart from the total RAM size?
And what happens if I say ramdisk_size=10240 (10MB) and I load only 1MB image into it.
Will the "unused" memory be freed? i.e. is the size dynamically allocated (<docs) and the ramdisk_size is only the upper bound?
Kalin.
