From 849e0ad257d259b8443c63d74e3bcc32ebf336af Mon Sep 17 00:00:00 2001 From: Jens Taprogge Date: Tue, 4 Sep 2012 17:01:13 +0200 Subject: Staging: ipack: implement ipack device table. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The modaliases look like ipack:fXvNdM, where X is the format version (8 bit) and N and M are the vendor and device ID represented as 32 bit hexadecimal numbers each. Using 32 bits allows us to define IPACK_ANY_ID as (~0) without interfering with the valid ids. The resulting modalias string for ipoctal.ko looks like this (once ipoctal provides a device table): alias: ipack:f01v000000F0d00000048* alias: ipack:f01v000000F0d0000002A* alias: ipack:f01v000000F0d00000022* (output from modinfo) Signed-off-by: Jens Taprogge Signed-off-by: Samuel Iglesias Gonsálvez Signed-off-by: Greg Kroah-Hartman --- include/linux/mod_devicetable.h | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'include/linux/mod_devicetable.h') diff --git a/include/linux/mod_devicetable.h b/include/linux/mod_devicetable.h index 6955045199b..999c4c25fbf 100644 --- a/include/linux/mod_devicetable.h +++ b/include/linux/mod_devicetable.h @@ -600,4 +600,11 @@ struct x86_cpu_id { #define X86_MODEL_ANY 0 #define X86_FEATURE_ANY 0 /* Same as FPU, you can't test for that */ +#define IPACK_ANY_ID (~0) +struct ipack_device_id { + __u8 format; /* Format version or IPACK_ANY_ID */ + __u32 vendor; /* Vendor ID or IPACK_ANY_ID */ + __u32 device; /* Device ID or IPACK_ANY_ID */ +}; + #endif /* LINUX_MOD_DEVICETABLE_H */ -- cgit v1.2.3-70-g09d2
