Subject: [PATCH] THE LINUX/I386 BOOT PROTOCOL - Breaking the 256 limit (ping)
Date: Sat, 26 Aug 2006 02:57:49 +0300 [thread overview]
Message-ID: <44EF8E7D.5060905@gmail.com> (raw)
In-Reply-To: <44D27F22.4080205@zytor.com>
Extending the kernel parameters to a 2048 bytes for
boot protocol >=2.02 of i386, ia64 and x86_64 architectures for
linux-2.6.18-rc4-mm2.
Current implementation allows the kernel to receive up to
255 characters from the bootloader. In current environment,
the command-line is used in order to specify many values,
including suspend/resume, module arguments, splash, initramfs
and more. 255 characters are not enough anymore.
