What size would you suggest for a ram_console allocation? I saw that the G1 is using 128k... That seems sufficient... Any reason why I should use more or less? Thanks Rob Stoddard

Hi Robert, It sounds like you need to register your new driver in the board file. For example, for the TMobile G1, you would edit the file arch/arm/mach-msm/board-trout.c and add a platform_device struct with name="ram_console" and add it to the list of platform devices in: static struct platform_device *devices[] __initdata = { ... }; Mike On Mon, Jan 5, 2009 at 2:47 PM, Dan Egnor <eg...@google.com> wrote: [+android-kernel], who can probably help you here.

I have written a driver which causes a kernel panic because my company requires functionality for testing "exceptional" behavior of all types, including (especially) kernel panics. Unfortunately, when I panic the phone, the /proc/last_kmsg file that contains the reason for the panic and other debug data does not appear. I have found that the ram_console driver (android/kernel/drivers/android/ram_console.c) is responsible for creating this file. This driver is a platform_driver, about which there's little information on the net. This driver initializes using the following code: static struct platform_driver ram_console_driver = { .probe = ram_console_driver_probe, .driver = { .name = "ram_console", }, }; static int __init ram_console_module_init(void) { int err; err = platform_driver_register(&ram_console_driver); return err; } The init function given above runs, however the probe function is never called. I am wondering what's necessary to make this probe function happen? Is it only called when the ram_console survives from the last run?
