Linux Utils 2.22 contains an update to CMEM for 2.6.28 kernels, although it
hasn't yet been validated. Here's the output of a "diff -c" with the Linux
Utils 2.21 cmemk.c:
***************
*** 1694,1700 ****
--- 1694,1704 ----
#ifdef USE_CLASS_DEVICE
class_device_create(cmem_class, NULL, MKDEV(cmem_major, 0), NULL, "cmem");
#else
+ #if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,27)
+ device_create(cmem_class, NULL, MKDEV(cmem_major, 0), NULL, "cmem");
+ #else
device_create(cmem_class, NULL, MKDEV(cmem_major, 0), "cmem");
+ #endif // LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,27)
#endif // USE_CLASS_DEVICE
#endif // USE_CLASS_SIMPLE
#endif // USE_UDEV
I hear the DSPLink team is being pressured to provide an update for 2.6.28, but
don't know the status of that.
