samsung smdk2440 ethernet driver

Hi, everyone I have a question about the ethernet driver of SMDK2440(ARM920T) board. I'm reading the kernel 2.6.26 now. The ethernet device in the SMDK2440 schematic from SAMSUNG is CS8900. However, the ethernet driver of SMDK2440 in kernel 2.6.26 is DM9000. Is there any reason why kernel 2.6.26

paing_init() in setup_arch() of ARM920T

Hi, everyone When "mem" option is not defined in command line and memory tag is not transferred by bootloader, how is meminfo structure in /arch/arm/kernel/setup.c set ? When is meminfo structure in /arch/arm/kernel/setup.c set to data of memory banks before it is sent as a argument in paging_ini

Re: Firing timers

hrtimer, is triggered based on softirq mechanism. and it can be triggered whether interrupt is enabled or disabled - two different modes. checkout kernel/hrtimer.c. within u can find the function enqueue_hrtimer(), which shows how the hrtimer can be enqueued into a red black tree. so similar

Re: How to make USB to work dynamically

Hi All, Udev (dynamic device management)is the best tool to achieve loading and unloading of device driver automatically. You need to write down an rule to support loading and unloading of driver in rules.d file. Sanjeev sharma On Thu, Jun 25, 2009 at 2:08 PM, Peter Chen wrote: > Hi, > > In our

Firing timers

Hi, I'm a student that want to study the kernel code. I have a simple question: If I set an hrtimer, I think that when it expires it raise a timer interrupt. What is the sequence of functions called at this point (in a recent kernel for example 2.6.29)? How I can know which is the timer expired? Th

Hi, In our platform, we use udev to implement that host/slave problem. Best Regards, Peter Chen On Thu, 2009-06-25 at 12:46 +0530, Arjun Joshi wrote: > Hi Greg, > > I am trying to make USB work dynamically on an OMAP board which has a > USB OTG controller. The board has a mini-AB receptacle.

Re: How to make USB to work dynamically

Hi Greg, I am trying to make USB work dynamically on an OMAP board which has a USB OTG controller. The board has a mini-AB receptacle. My target is that whenever I insert a mini-B cable the gadget related kernel modules must be loaded automatically so that my board works as mass storage devi
