From 060e48824720626ae71cbff2328ec91f4aab1839 Mon Sep 17 00:00:00 2001 From: Doug Ambrisko Date: Fri, 5 May 2006 16:10:45 +0000 Subject: Enhance the Linux emulation layer to make MegaRAID SAS managements tool happy. Add back in a scheme to emulate old type major/minor numbers via hooks into stat, linprocfs to return major/minors that Linux app's expect. Currently only /dev/null is always registered. Drivers can register via the Linux type shim similar to the ioctl shim but by using linux_device_register_handler/linux_device_unregister_handler functions. The structure is: struct linux_device_handler { char *bsd_driver_name; char *linux_driver_name; char *bsd_device_name; char *linux_device_name; int linux_major; int linux_minor; int linux_char_device; }; Linprocfs uses this to display the major number of the driver. The soon to be available linsysfs will use it to fill in the driver name. Linux_stat uses it to translate the major/minor into Linux type values. Note major numbers are dynamically assigned via passing in a -1 for the major number so we don't need to keep track of them. This is somewhat needed due to us switching to our devfs. MegaCli will not run until I add in the linsysfs and mfi Linux compat changes.
