2011-05-04ixgbe: improve EEPROM read/write operationsEmil Tantilov
Introduce buffered read/writes which greatly improves performance on parts with large EEPROMs. Previously reading/writing a word requires taking/releasing of synchronization semaphores which adds 10ms to each operation. The optimization is to read/write in buffers, but make sure the semaphore is not held for >500ms according to the datasheet. Since we can't read the EEPROM page size ixgbe_detect_eeprom_page_size() is used to discover the EEPROM size when needed and keeps the result in word_page_size for the rest of the run time. Use buffered reads for ethtool -e. Signed-off-by: Emil Tantilov <emil.s.tantilov@intel.com> Tested-by: Evan Swanson <evan.swanson@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2011-04-13ixgbe: DCB, misallocated packet buffer size with X540 deviceJohn Fastabend
The X540 device has a smaller packet buffer but the DCB configuration never took this into account. Under stress this can result in the DMA engine hanging and TX Unit hang occurring to reset the device. This patch reworks the packet buffer allocation routine used for DCB on 82599 and X540 devices to account for RX packet buffer sizes. This fixes the immediate hang. We should consolidate the various hardware specific routines for configuring features into a single routine. This will make it much harder to miss feature cases like this.

2010-11-16ixgbe: DCB set PFC high and low water marks per data sheet specsJohn Fastabend
Currently the high and low water marks for PFC are being set conservatively for jumbo frames. This means the RX buffers are being underutilized in the default 1500 MTU. This patch fixes this so that the water marks are set as described in the data sheet considering the MTU size. The equation used is, RTT * 1.44 + MTU * 1.44 + MTU Where RTT is the round trip time and MTU is the max frame size in KB. To avoid floating point arithmetic FC_HIGH_WATER is defined ((((RTT + MTU) * 144) + 99) / 100) + MTU This changes how the hardware field fc.low_water and fc.high_water are used. With this change they are no longer storing the actual low water and high water markers but are storing the required head room in the buffer. This simplifies the logic and we do not need to account for the size of the buffer when setting the thresholds. Testing with iperf and 16 threads showed a slight uptick in throughput over a single traffic class .1-.2Gbps and a reduction in pause frames. Without the patch a 30 second run would show ~10-15 pause frames being transmitted with the patch ~2-5 are seen. Test were run back to back with 82599. Note RXPBSIZE is in KB and low and high water marks fields are also in KB. However the FCRT* registers are 32B granularity and right shifted 5 into the register, (((rx_pbsize - water_mark) * 1024) / 32) << 5 is the most explicit conversion here we simplify (rx_pbsize - water_mark) * 32 << 5 = (rx_pbsize - water_mark) << 10 This patch updates the PFC thresholds and legacy FC thresholds.

This adds support for a new copper device for 82599, device id 0x151c. This 82599 10GBase-T device uses the PHY's internal temperature sensor to guard against over-temp conditions. In this scenario the PHY will be put in a low power mode and link will no longer be able to transmit or receive any data. When this occurs, the over-temp interrupt is latched and driver logs this error message. A HW reset or power cycle is required to clear this status.

The current code has some flaws in it when performing autonegotiation, especially on KX/KX4 links. This patch updates the code to better handle the autonegotiation states on link setup. The patch also removes a redundant link configuration call on driver load, and moves link configuration to the ->open() path.
