From: Fredrik Noring <noring@nocrew.org> To: linux-mips@vger.kernel.org Subject: [PATCH 044/120] MIPS: PS2: ROM: Sysfs module to inspect ROM files Date: Sun, 1 Sep 2019 17:53:42 +0200 Message-ID: <db87261b1911924dcfcce59ad1840f72caff30d7.1567326213.git.noring@nocrew.org> (raw) In-Reply-To: <cover.1567326213.git.noring@nocrew.org> The ROM sysfs module gives information on the ROM file names, sizes, and addresses. For example, listing all files of ROM0: # cat /sys/rom/rom0/file/*/name | column RESET VBLANK RMRESET MCSERV XSIFCMD ROMDIR IOMAN OSDVER PADMAN XCDVDMAN EXTINFO MODLOAD - CDVDMAN XCDVDFSV ROMVER ROMDRV IOPBOOT CDVDFSV XFILEIO SBIN ADDDRV OSDCNF FILEIO XSIO2MAN LOGO STDIO - CLEARSPU XMTAPMAN IOPBTCONF SIFMAN TBIN UDNL XMCMAN ... Viewing for example the contents of the ROM file ROMVER using /dev/mem: # grep -l ROMVER /sys/rom/rom0/file/*/name /sys/rom/rom0/file/3/name # cd /sys/rom/rom0/file/3 # dd if=/dev/mem bs=$(cat size) iflag=skip_bytes \ skip=$(( $(cat data) )) count=1 status=none 0170EC20030227 For convenience, the ROMVER file is also available directly in sysfs: # ls /sys/rom/rom0/version date number region type # cat /sys/rom/rom0/version/* 2003-02-27 0x0170 Europe CEX The CEX type indicates that it is a retail machine, as opposed to for example DEX that would be a debug machine.
