Device Drivers for System on Chip (SOC)












0















I want to read the GPS data from my android phone inside the kernel space. I want to write a device driver for my GPS and request data through it. But unlike external devices I could not find the Vendor Id and device Id of the GPS hardware or the SOC on which it is installed. Can someone help me with how to collect the details required for writing the driver?



Thanks.

          You already have found one of many problems with SOC and device drivers. Therefore another approach is used in the linux kernel: Platform driver and Platform devices. You wont need any Vendor IDs and such stuff.


          I recommend you to read some tutorials and get started with it:

          Readme: https://www.kernel.org/doc/Documentation/driver-model/platform.txt

          Code example for CAN: https://github.com/torvalds/linux/tree/master/drivers/net/can/ifi_canfd

          Disscussion about difference: What is the difference between a Linux platform driver and normal device driver?



          Sadly I am not able to answer your questions on how to get those id's.

                    For other uses, see Quarantine (disambiguation). Signal flag "Lima" called the "Yellow Jack" which when flown in harbor means ship is under quarantine. A simple yellow flag (also called the "Yellow Jack") had historically been used to signal quarantine (it stands for Q among signal flags), but now indicates the opposite, as a signal of a ship free of disease that requests boarding and inspection. A quarantine is used to separate and restrict the movement of people; it is 'a restraint upon the activities or communication of persons or the transport of goods designed to prevent the spread of disease or pests', for a certain period of time. [1] This is often used in connection to disease and illness, such as those who may possibly have been exposed to a communicable disease. [2] The term is often erroneously used to mean medical isolation, which is "to separate ill persons who have a communicable disease from those who are healthy...
