* scsi: hisi_sas: add v2 hw internal abort timeout workaroundJohn Garry2017-04-111-0/+1
| | | | | | | | | | | | | | | | | This patch is a workaround for a SoC bug where an internal abort command may timeout. In v2 hw, the channel should become idle in order to finish abort process. If the target side has been sending HOLD, host side channel failed to complete the frame to send, and can not enter the idle state. Then internal abort command will timeout. As this issue is only in v2 hw, we deal with it in the hw layer. Our workaround solution is: If abort is not finished within a certain period of time, we will check HOLD status. If HOLD has been sending, we will send break command. Signed-off-by: John Garry <john.garry@huawei.com> Signed-off-by: Xiaofei Tan <tanxiaofei@huawei.com> Signed-off-by: Martin K.

* scsi: hisi_sas: workaround a SoC SATA IO processing bugXiaofei Tan2017-04-111-0/+2
| | | | | | | | | | | | | | | | | | | | | | | This patch provides a workaround a SoC bug where SATA IPTTs for different devices may conflict. The workaround solution requests the following: 1. SATA device id must be even and not equal to SAS IPTT. 2. SATA device can not share the same IPTT with other SAS or SATA device. Besides we shall consider IPTT value 0 is reserved for another SoC bug (STP device open link at firstly after SAS controller reset). To sum up, the solution is: Each SATA device uses independent and continuous 32 even IPTT from 64 to 4094, then v2 hw can only support 63 SATA devices. All SAS device(SSP/SMP devices) share odd IPTT value from 1 to 4095.

* scsi: hisi_sas: workaround STP link SoC bugXiaofei Tan2017-04-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | After resetting the controller, the process of scanning SATA disks attached to an expander may fail occasionally. The issue is that the controller can't close the STP link created by target if the max link time is 0. To workaround this issue, we reject STP link after resetting the controller, and change the corresponding PHY to accept STP link only after receiving data. We do this check in cq interrupt handler. In order not to reduce efficiency, we use an variable to control whether we should check and change PHY to accept STP link. The function phys_reject_stp_links_v2_hw() should be called after resetting the controller. The solution of another SoC bug "SATA IO timeout", that also uses the same register to control STP link, is not effective before the PHY accepts STP link.

* scsi: hisi_sas: remove hisi_sas_port_deformed()John Garry2017-03-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | Currently when a root PHY is deformed from a asd_sas_port we try to release the slots in the LLDD, and fail. Regardless, it is not right to release this early. This patch removes the deformed function. As it was before, port deformation is still done in hisi_sas_phy_down(). It would be nice to actually remove the hisi_sas_port_{de}formed() pair, however we cannot as we need to know the asd_sas_port index libsas has associated with an asd_sas_phy. The hw does actually generate a port id for a PHY, but this seems to a random number, so ignored for this purpose. This patch also changes the code to link slots to the hisi_sas_device, and not hisi_sas_port.

| | | | | | | | | | | | | | | Currently the all the slot processing for the completion queue is done in ISR context. It is judged that the slot processing can take a long time, especially when a SATA NCQ completes (upto 32 slots). So, as a solution, defer the bulk of the ISR processing to tasklet context.

* scsi: hisi_sas: alloc queue id of slot according to device idXiang Chen2016-11-251-2/+2
| | | | | | | | | | | | | | | | | | | | | Currently slots are allocated from queues in a round-robin fashion. This causes a problem for internal commands in device mode. For this mode, we should ensure that the internal abort command is the last command seen in the host for that device. We can only ensure this when we place the internal abort command after the preceding commands for device that in the same queue, as there is no order in which the host will select a queue to execute the next command. This queue restriction makes supporting scsi mq more tricky in the future, but should not be a blocker. Note: Even though v1 hw does not support internal abort, the allocation method is chosen to be the same for consistency.

| | | | | | | | | | | | | | | | | | | The hip06 D03 and hip07 D05 boards have different reference clock frequencies for the SAS controller. Register PHY_CTRL needs to be programmed differently according to this frequency, so add support for this. The default register setting in PHY_CTRL is for 50MHz, so only update this register when the refclk frequency is 66MHz. For ACPI we expect the _RST handler to set the correct value for PHY_CTRL (we're forced to take different approach for DT and ACPI as ACPI does not support fixed-clock device).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add main code for internal abort functionality. The internal abort features allows the host controller to abort commands which are still active in the controller but have not yet been sent to the slave device. Typically a command only spends a relatively short time in the controller when compared to the amount of the time after it is sent to the slave device. Two modes of internal abort are supported: - device - individual command For device, when the internal abort is issued all commands in the host for that device are aborted. For a single command, only that command is aborted if it is still in the host. In HW the internal abort command is executed similar to any other sort of command, like SSP.
