Where the value printed is an offset (whose range will always fit) the cast uses a 32-bit type, otherwise, where it is a host memory address, the pointer is output directly with %p. Also the remaining `0x' prefix is dropped for consistency across these messages. Tested with both 32-bit and 64-bit compilation, as well as at the run time (with the debug messages affected enabled).

* | amd-xgbe: Base AXI DMA cache settings on device treeLendacky, Thomas2014-07-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default cache operations for ARM64 were changed during 3.15. To use coherent operations a "dma-coherent" device tree property is required. If that property is not present in the device tree node then the non-coherent operations are assigned for the device. Add support to the amd-xgbe driver to assign the AXI DMA cache settings based on whether the "dma-coherent" property is present in the device node. If present, use settings that work with the caches. If not present, use settings that do not look at the caches. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* | amd-xgbe: Performance enhancementsLendacky, Thomas2014-07-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch provides some general performance enhancements for the driver: - Modify the default coalescing settings (reduce usec, increase frames) - Change the AXI burst length to 256 bytes (default was 16 bytes which was smaller than a cache line) - Change the AXI cache settings to write-back/write-allocate which allocate cache entries for received packets during the DMA since the packet will be processed soon afterwards - Combine ioread/iowrite when disabling both the Tx and Rx interrupts - Change to processing the Tx/Rx channels in pairs - Only recycle the Rx descriptors when a threshold of dirty descriptors is reached Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S.

* | amd-xgbe: Call netif_napi_del on ndo_stop operationLendacky, Thomas2014-07-08
| | | | | | | | | | | | | | | | | | | | | | | | Currently the napi context is added using netif_napi_add each time the ndo_open operation is called. However, there is not a corresponding netif_napi_del call during the ndo_stop operation. If the device ndo_open operation was called more than once an infinite loop occurs during module unload.

| | | | | | | | | | | | | | | | | | | | | | When initializing the MTL interrupts the interrupt status register is written to instead of the interrupt enable register. Since no MTL interrupts are being enabled and the default state is for MTL interrupts to be disabled this did not cause a problem, but needs to be fixed to target the correct register.

* | amd-xgbe: Fix debugfs compatibility change with kstrtouintLendacky, Thomas2014-07-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The initial change from sscanf to kstrtouint broke backward compatbility by using a base of "0" in the kstrtouint call. This allowed for entering decimal, hexadecimal or octal as input where previously the sscanf always interpreted the input as hexadecimal. Additionally, -EIO was returned on error prior to this change and now it is whatever the error value that is returned by kstrtouint. Change the base value of the kstrtouint from 0 to 16 and return -EIO on error. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Reported-by: Joe Perches <joe@perches.com> Signed-off-by: David S.

* | amd-xgbe: Change destination address filtering supportLendacky, Thomas2014-06-26
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently the driver makes use of the additional mac address registers in the hardware to provide perfect filtering. The hardware can also have a set of hash table registers that can be used for imperfect filtering. By using imperfect filtering the additional mac address registers can be used for layer 2 filtering support. Use the hash table registers if the device has them.

* | amd-xgbe: Add support for VLAN filteringLendacky, Thomas2014-06-26
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for (imperfect) filtering of VLAN tag ids using a 16-bit filter hash table. When VLANs are added, a 4-bit hash is calculated with the result indicating the bit in the hash table to set. This table is used by the hardware to drop packets with a VLAN id that does not hash to a set bit in the table. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S.

No longer will we need protocol aware firewall filtering modules, it can all live in userspace. At the core of nftables is a, for lack of a better term, virtual machine that executes byte codes to inspect packet or metadata (arriving interface index, etc.) and make verdict decisions. Besides support for loading packet contents and comparing them, the interpreter supports lookups in various datastructures as fundamental operations. For example sets are supports, and therefore one could create a set of whitelist IP address entries which have ACCEPT verdicts attached to them, and use the appropriate byte codes to do such lookups. Since the interpreted code is composed in userspace, userspace can do things like optimize things before giving it to the kernel. Another major improvement is the capability of atomically updating portions of the ruleset. In the existing netfilter implementation, one has to update the entire rule set in order to make a change and this is very expensive. Userspace tools exist to create nftables rules using existing netfilter rule sets, but both kernel implementations will need to co-exist for quite some time as we transition from the old to the new stuff. Kudos to Patrick McHardy, Pablo Neira Ayuso, and others who have worked so hard on this. 2) Daniel Borkmann and Hannes Frederic Sowa made several improvements to our pseudo-random number generator, mostly used for things like UDP port randomization and netfitler, amongst other things. In particular the taus88 generater is updated to taus113, and test cases are added. 3) Support 64-bit rates in HTB and TBF schedulers, from Eric Dumazet and Yang Yingliang. 4) Add support for new 577xx tigon3 chips to tg3 driver, from Nithin Sujir. 5) Fix two fatal flaws in TCP dynamic right sizing, from Eric Dumazet, Neal Cardwell, and Yuchung Cheng. 6) Allow IP_TOS and IP_TTL to be specified in sendmsg() ancillary control message data, much like other socket option attributes. From Francesco Fusco. 7) Allow applications to specify a cap on the rate computed automatically by the kernel for pacing flows, via a new SO_MAX_PACING_RATE socket option. From Eric Dumazet. 8) Make the initial autotuned send buffer sizing in TCP more closely reflect actual needs, from Eric Dumazet. 9) Currently early socket demux only happens for TCP sockets, but we can do it for connected UDP sockets too. Implementation from Shawn Bohrer. 10) Refactor inet socket demux with the goal of improving hash demux performance for listening sockets. With the main goals being able to use RCU lookups on even request sockets, and eliminating the listening lock contention. From Eric Dumazet. 11) The bonding layer has many demuxes in it's fast path, and an RCU conversion was started back in 3.11, several changes here extend the RCU usage to even more locations. From Ding Tianhong and Wang Yufen, based upon suggestions by Nikolay Aleksandrov and Veaceslav Falico. 12) Allow stackability of segmentation offloads to, in particular, allow segmentation offloading over tunnels. From Eric Dumazet. 13) Significantly improve the handling of secret keys we input into the various hash functions in the inet hashtables, TCP fast open, as well as syncookies. From Hannes Frederic Sowa. The key fundamental operation is "net_get_random_once()" which uses static keys. Hannes even extended this to ipv4/ipv6 fragmentation handling and our generic flow dissector. 14) The generic driver layer takes care now to set the driver data to NULL on device removal, so it's no longer necessary for drivers to explicitly set it to NULL any more. Many drivers have been cleaned up in this way, from Jingoo Han. 15) Add a BPF based packet scheduler classifier, from Daniel Borkmann. 16) Improve CRC32 interfaces and generic SKB checksum iterators so that SCTP's checksumming can more cleanly be handled. Also from Daniel Borkmann. 17) Add a new PMTU discovery mode, IP_PMTUDISC_INTERFACE, which forces using the interface MTU value. This helps avoid PMTU attacks, particularly on DNS servers. From Hannes Frederic Sowa. 18) Use generic XPS for transmit queue steering rather than internal (re-)implementation in virtio-net.

| * amd/7990: Remove extern from function prototypesJoe Perches2013-09-24
| | | | | | | | | | | | | | | | | | | | | | | | There are a mix of function prototypes with and without extern in the kernel sources. Standardize on not using extern for function prototypes. Function prototypes don't need to be written with extern. extern is assumed by the compiler. Its use is as unnecessary as using auto to declare automatic/local variables in a block.
