| * | | altera tse: Error-Bit on tx-avalon-stream always set.Andreas Oetken2015-04-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Error-Bit on the avalon streaming interface of the tx-dma-channel was always set. In SGMII configurations this leads to error-symbols on the PCS and packet-rejection on the receiver side (e.g. SGMII/1000Base-X connected switch). This only applies to the tse-configuration with MSGDMA. This issue was detected and fixed on a custom board with a direct connection to a Marvell switch in SGMII-PHY-Mode. (incl. custom patches for SGMII-PCS). According to the datasheet if ff_tx_err (avalon-streaming) is set it is forwarded to gm_tx_err. As a result the PCS is forwarding the error by sending a "/V/"-caracter. Signed-off-by: Andreas Oetken <ennoerlangen@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

So the non-failing requirement is too strong without any obvious reason. Drop __GFP_NOFAIL and reorganize the code to have the failure paths easier. The same applies to _c4iw_write_mem_dma_aligned which uses __GFP_NOFAIL and then checks the return value and returns -ENOMEM on failure. This doesn't make any sense what so ever. Either the allocation cannot fail or it can. del_filter_wr seems to be safe as well because the filter entry is not marked as pending and the return value is propagated up the stack up to c4iw_destroy_listen.

Mitch provides a fix for i40e, where VFs were gone and the associated VSI's had been removed and the rings were not stopped, which in some circumstances cased memory corruption or DMAR errors. So stop all the rings associated with each VF before releasing its resources. Also cleaned up a poorly indented piece of code. Fixes VF link state, where VF devices were assuming link is up unless told otherwise, which means that VFs instantiated on a PF with no link, would report the wrong state. Anjali adds support to add Flow director Sideband rules for a VF from it's PF. Fixes a recently discovered hardware issue, where after a VFLR hardware might be indicating to us a reset completion little too early, so wait another 10 msec for cache to be cleaned up. Jesse enables the user to dump the internal hardware state for better debugging by allowing a bash script to acquire information about the internal hardware state. The data output to the kernel log is collected by the script and can then be sent to Intel. Also fixed a possible failure path to allocate memory that was found by smatch.

Even though the VFs were gone, and the associated VSIs were removed, the rings were not stopped, and in some circumstances the hardware would continue to access the memory formerly used by the rings, causing memory corruption or DMAR errors, both of which would lead to general malaise of the kernel. To relieve this condition, explicitly stop all the rings associated with each VF before releasing its resources.

This switches the driver into using atomic assignments instead of the spinlock mechanisms previously employed. Based on initial patch from Yuval Mintz & Ariel Elior I basically added softirq starvation avoidance, and mixture of atomic operations, plain writes and barriers. Note this slightly reduces the overhead for this driver when no busy_poll sockets are in use.

That's fine, but that only works once. The timer is started in relative mode, so the expiry value gets overwritten with the absolut expiry time (now + expiry). So once the timer expired, a new call to hrtimer_start_expires results in an immidiately expired timer, because the expiry value is already in the past. Use the proper mechanisms to (re)start the timer in the intended way. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: "David S.

These can be accessed via the arch-specific {ld,st}_le{16,32}() inlines in arch/powerpc/include/asm/swab.h. However, gcc is perfectly capable of generating the byte-reversing load/store instructions when using the normal, generic cpu_to_le*() and le*_to_cpu() functions eaning the arch-specific functions don't have much point. Worse the "le" in the names of the arch specific functions is now misleading, because they always generate byte-reversing forms, but some ppc machines can now run a little-endian kernel. To start getting rid of the arch-specific forms, this patch removes them from all the old Power Macintosh drivers, replacing them with the generic byteswappers.

This is due to the difficulty in performing this operation, since it is a FIFO which makes updating anything other than head or tail very difficult. To fix this, modify validate_msg_size to ensure that we error out later when trying to transmit the message that could be oversized. This will generally be a rare condition, as it requires the FIFO to include a message larger than the max_size negotiated during mailbox connect. Note that max_size is always smaller than rx.size so it should be safe to use here. Also, update the update_max_size function header comment to clearly indicate that it does not drop all oversized messages, but only those at the head of the FIFO.

This ensures that we continually check the mailbox, as well as handle other tasks while the device is down.

This flow is necessary as it prevents the PF<->SM mailbox from being flooded by the VF messages, which normally trigger a message to the PF. This helps prevent the case where we see a PF mailbox timeout.
