amd-xgbe: Fix the ECC-related bit position definitions

2017-03-30T07:44:02+00:00

[ Upstream commit f43feef4e6acde10857fcbfdede790d6b3f2c71d ] The ECC bit positions that describe whether the ECC interrupt is for Tx, Rx or descriptor memory and whether the it is a single correctable or double detected error were defined in incorrectly (reversed order). Fix the bit position definitions for these settings so that the proper ECC handling is performed. Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

amd-xgbe: Fix jumbo MTU processing on newer hardware

2017-03-30T07:44:00+00:00

[ Upstream commit 622c36f143fc9566ba49d7cec994c2da1182d9e2 ] Newer hardware does not provide a cumulative payload length when multiple descriptors are needed to handle the data. Once the MTU increases beyond the size that can be handled by a single descriptor, the SKB does not get built properly by the driver. The driver will now calculate the size of the data buffers used by the hardware. The first buffer of the first descriptor is for packet headers or packet headers and data when the headers can't be split. Subsequent descriptors in a multi-descriptor chain will not use the first buffer. The second buffer is used by all the descriptors in the chain for payload data. Based on whether the driver is processing the first, intermediate, or last descriptor it can calculate the buffer usage and build the SKB properly. Tested and verified on both old and new hardware.

amd-xgbe: Enable IRQs only if napi_complete_done() is true

2017-03-22T11:57:00+00:00

[ Upstream commit d7aba644ffdebf756e51e26a2229055211838e89 ] Depending on the hardware, the amd-xgbe driver may use disable_irq_nosync() and enable_irq() when an interrupt is received to process Rx packets. If the napi_complete_done() return value isn't checked an unbalanced enable for the IRQ could result, generating a warning stack trace. Update the driver to only enable interrupts if napi_complete_done() returns true. Reported-by: Jeremy Linton Signed-off-by: Tom Lendacky Signed-off-by: David S.

amd-xgbe: Don't overwrite SFP PHY mod_absent settings

2017-03-22T11:56:58+00:00

[ Upstream commit 2697ea5a859b83ca49511dcfd98daf42584eb3cf ] If an SFP module is not present, xgbe_phy_sfp_phy_settings() should return after applying the default settings. Currently there is no return statement and the default settings are overwritten. Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

amd-xgbe: Be sure to set MDIO modes on device (re)start

2017-03-22T11:56:58+00:00

[ Upstream commit b42c6761fd1651f564491b53016046c9ebf0b2a9 ] The MDIO register mode is set when the device is probed. But when the device is brought down and then back up, the MDIO register mode has been reset. Be sure to reset the mode during device startup and only change the mode of the address specified.

amd-xgbe: Stop the PHY before releasing interrupts

2017-03-22T11:56:58+00:00

[ Upstream commit 402168b4c2dc0734b8fbd282eff77da0275c5129 ] Some configurations require the use of the hardware's MDIO support to communicate with external PHYs. The MDIO commands indicate completion through the device interrupt. When bringing down the device the interrupts were released before stopping the external PHY, resulting in MDIO command timeouts. Move the stopping of the PHY to before the releasing of the interrupts. Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

amd-xgbe: Check xgbe_init() return code

2017-01-22T21:57:14+00:00

The xgbe_init() routine returns a return code indicating success or failure, but the return code is not checked. Add code to xgbe_init() to issue a message when failures are seen and add code to check the xgbe_init() return code. Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller

amd-xgbe: Add a hardware quirk for register definitions

2017-01-22T21:57:14+00:00

A newer version of the hardware is using the same PCI ids for the network device but has altered register definitions for determining the window settings for the indirect PCS access. Add support to check for this hardware and if found use the new register values. Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller

amd-xgbe: Fix IRQ processing when running in single IRQ mode

2017-01-06T20:34:05+00:00

When running in single IRQ mode, the additional IRQ routines were being skipped because only the XGMAC interrupt status was being checked. Update the code so that the additional IRQ routines are checked whenever an interrupt is received. Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller

clocksource: Use a plain u64 instead of cycle_t

2016-12-25T10:04:12+00:00

There is no point in having an extra type for extra confusion. u64 is unambiguous. Conversion was done with the following coccinelle script: @rem@ @@ -typedef u64 cycle_t; @fix@ typedef cycle_t; @@ -cycle_t +u64 Signed-off-by: Thomas Gleixner Cc: Peter Zijlstra Cc: John Stultz
