    text
    copied!<p>I need to modify a kernel module located in Linux 3.2.0. Within <code>drivers/staging/bcm</code>, the driver should support the device id <code>198F:015E</code>, instead in the <code>InterfaceInit.h</code> file, it was mentioned as <code>198F:15E</code>, I changed that to <code>015E</code> but still, after successful compilation, the new device id's are not being picked up by the kernel.</p> <p>Here is the output of <code>modinfo</code>:</p> <pre><code>filename: &lt;somewhere/&gt;bcm_wimax.ko license: GPL version: 5.2.45 description: Beceem Communications Inc. WiMAX driver srcversion: D6016018ABCFFD16AF31D22 alias: usb:v19D2p0007d*dc*dsc*dp*ic*isc*ip* alias: usb:v0489pE017d*dc*dsc*dp*ic*isc*ip* alias: usb:v19D2p0132d*dc*dsc*dp*ic*isc*ip* alias: usb:v198FpBCCDd*dc*dsc*dp*ic*isc*ip* alias: usb:v198Fp0220d*dc*dsc*dp*ic*isc*ip* alias: usb:v198Fp0210d*dc*dsc*dp*ic*isc*ip* alias: usb:v198Fp0300d*dc*dsc*dp*ic*isc*ip* depends: vermagic: 3.2.0-26-generic-pae SMP mod_unload modversions 686 parm: debug:Debug level (0=none,...,16=all) (uint) </code></pre> <p>My <code>198F:015E</code> is still not appearing! Strangely after beginning the compilation, I can see a file called bcm_wimax.mod.c getting generated inside the module source folder. Inside that, I found out the <code>modinfo</code> alias thing. Which looks like:</p> <pre class="lang-c prettyprint-override"><code> #include &lt;linux/module.h&gt; #include &lt;linux/vermagic.h&gt; #include &lt;linux/compiler.h&gt; MODULE_INFO(vermagic, VERMAGIC_STRING); struct module __this_module __attribute__((section(".gnu.linkonce.this_module"))) = { .name = KBUILD_MODNAME, .init = init_module, #ifdef CONFIG_MODULE_UNLOAD .exit = cleanup_module, #endif .arch = MODULE_ARCH_INIT, }; MODULE_INFO(staging, "Y"); static const struct modversion_info ____versions[] __used __attribute__((section("__versions"))) = { }; static const char __module_depends[] __used __attribute__((section(".modinfo"))) = "depends="; MODULE_ALIAS("usb:v198Fp0300d*dc*dsc*dp*ic*isc*ip*"); MODULE_ALIAS("usb:v198Fp0210d*dc*dsc*dp*ic*isc*ip*"); MODULE_ALIAS("usb:v198Fp0220d*dc*dsc*dp*ic*isc*ip*"); MODULE_ALIAS("usb:v198FpBCCDd*dc*dsc*dp*ic*isc*ip*"); MODULE_ALIAS("usb:v19D2p0132d*dc*dsc*dp*ic*isc*ip*"); MODULE_ALIAS("usb:v0489pE017d*dc*dsc*dp*ic*isc*ip*"); MODULE_ALIAS("usb:v19D2p0007d*dc*dsc*dp*ic*isc*ip*"); MODULE_INFO(srcversion, "D6016018ABCFFD16AF31D22"); </code></pre> <p>But I tried to modify <code>bcm_wimax.mod.c</code> but after compiling, the file got reverted back to it's original condition, removing my edits. How can I get to add my <code>198f:015e</code> to the module alias section?</p>
