Greetings, I am working with the latest 2.6.7 kernel source on a ppc radstone PPC7A board and was curious if anyone was in the process or planned on porting the gt64260_eth driver to support the 2.6.x kernel.
Not being familiar with the gt64260 Ethernet device or code, I plan to take it line by line. I have attempted to use the driver from the ppc.bkbits.net 2.4 development tree and currently have only changed the dev = init_etherdev(dev, sizeof (gt_eth_priv)); to dev = alloc_etherdev(sizeof (gt_eth_priv_struct )); Shortly after, when attempting to allocate the Tx and Rx page buffers, I get an exception in the uncachedPages function. I have traced the problem to the pmd_present?(*pmd) function in va_to_pte(addr) returning 0. I dumped the values of pmd, init_mm, and pmd in the va_to_pte() and the values seemed O.K., so I commented out the pmd_present?(*pmd) check but was once again stopped by the pte_present(*pte) check. I have seen the driver operate under 2.4.26 dev tree from ppc.bkbits.net where this problem does not occur. One difference I have noticed is that during initialization of the 2.6.7 kernel, I do not get the following output. Buffer-cache hash table entries: Page-cache hash table entries: The filemap.c, where the "Page-cache " printk resides in 2.4, looks heavily reworked, so I don't suspect this is an issue? ** Sent via the linuxppc-embedded mail list.
