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 --- scripts/mod/file2alias.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'scripts/mod') diff --git a/scripts/mod/file2alias.c b/scripts/mod/file2alias.c index 7ed6864ef65..3c22bda8fdf 100644 --- a/scripts/mod/file2alias.c +++ b/scripts/mod/file2alias.c @@ -966,6 +966,21 @@ static int do_isapnp_entry(const char *filename, } ADD_TO_DEVTABLE("isapnp", struct isapnp_device_id, do_isapnp_entry); +/* Looks like: "ipack:fNvNdN". */ +static int do_ipack_entry(const char *filename, + struct ipack_device_id *id, char *alias) +{ + id->vendor = TO_NATIVE(id->vendor); + id->device = TO_NATIVE(id->device); + strcpy(alias, "ipack:"); + ADD(alias, "f", id->format != IPACK_ANY_ID, id->format); + ADD(alias, "v", id->vendor != IPACK_ANY_ID, id->vendor); + ADD(alias, "d", id->device != IPACK_ANY_ID, id->device); + add_wildcard(alias); + return 1; +} +ADD_TO_DEVTABLE("ipack", struct ipack_device_id, do_ipack_entry); + /* * Append a match expression for a single masked hex digit. * outp points to a pointer to the character at which to append. -- cgit v1.2.3-70-g09d2
