2021-04-09habanalabs: enable all IRQs for user interrupt supportOfir Bitton3-2/+74
In order to support user interrupts, driver must enable all MSI-X interrupts for any case user will trigger them. We differentiate between a valid user interrupt and a non valid one.

2021-04-09habanalabs: reset device in case of sync errorOhad Sharabi5-0/+52
As the F/wW is the first to detect out of sync event, a new event is added to notify the driver on such event. In which case the driver performs hard reset. Signed-off-by: Ohad Sharabi <osharabi@habana.ai> Reviewed-by: Oded Gabbay <ogabbay@kernel.org> Signed-off-by: Oded Gabbay <ogabbay@kernel.org>

2021-04-09habanalabs: fail reset if device is not idleOded Gabbay1-14/+12
After any reset (soft or hard) the device (the engines/QMANs) should be idle. If they are not idle, fail the reset. If it is soft-reset, the driver will try to do hard-reset automatically. If it is hard-reset, the driver will make the device non-operational. Signed-off-by: Oded Gabbay <ogabbay@kernel.org>
2021-04-09habanalabs: reset after device is actually releasedOded Gabbay1-16/+16
The device is actually released only after the refcnt of the hpriv structure is 0, which means all its contexts were closed. If we reset the device while a context is still open, there are possibilities for unexpected behavior and crashes. For example, if the process has a mapping of a register block that is now currently being reset, and the process writes/reads to that block during the reset, the device can get stuck.

2021-04-09clk: mvebu: armada-37xx-periph: Fix workaround for switching from L1 to L0Pali Rohár1-6/+39
When CPU frequency is at 250 MHz and set_rate() is called with 500 MHz (L1) quickly followed by a call with 1 GHz (L0), the CPU does not necessarily stay in L1 for at least 20ms as is required by Marvell errata. This situation happens frequently with the ondemand cpufreq governor and can be also reproduced with userspace governor. In most cases it causes CPU to crash. This change fixes the above issue and ensures that the CPU always stays in L1 for at least 20ms when switching from any state to L0.

2021-04-09cpufreq: armada-37xx: Fix the AVS value for load L1Pali Rohár1-0/+37
The original CPU voltage value for load L1 is too low for Armada 37xx SoC when base CPU frequency is 1000 or 1200 MHz. It leads to instabilities where CPU gets stuck soon after dynamic voltage scaling from load L1 to L0. Update the CPU voltage value for load L1 accordingly when base frequency is 1000 or 1200 MHz. The minimal L1 value for base CPU frequency 1000 MHz is updated from the original 1.05V to 1.108V and for 1200 MHz is updated to 1.155V. This minimal L1 value is used only in the case when it is lower than value for L0. This change fixes CPU instability issues on 1 GHz and 1.2 GHz variants of Espressobin and 1 GHz Turris Mox. Marvell previously for 1 GHz variant of Espressobin provided a patch [1] suitable only for their Marvell Linux kernel 4.4 fork which workarounded this issue. Patch forced CPU voltage value to 1.108V in all loads. But such change does not fix CPU instability issues on 1.2 GHz variants of Armada 3720 SoC. During testing we come to the conclusion that using 1.108V as minimal value for L1 load makes 1 GHz variants of Espressobin and Turris Mox boards stable. And similarly 1.155V for 1.2 GHz variant of Espressobin. These two values 1.108V and 1.155V are documented in Armada 3700 Hardware Specifications as typical initial CPU voltage values. Discussion about this issue is also at the Armbian forum [2].

Remove the .set_parent method in clk_pm_cpu_ops. This method was supposed to be needed by the armada-37xx-cpufreq driver, but was never actually called due to wrong assumptions in the cpufreq driver. After this was fixed in the cpufreq driver, this method is not needed anymore.

2021-04-09cpufreq: armada-37xx: Fix setting TBG parent for load levelsMarek Behún1-12/+23
With CPU frequency determining software [1] we have discovered that after this driver does one CPU frequency change, the base frequency of the CPU is set to the frequency of TBG-A-P clock, instead of the TBG that is parent to the CPU. This can be reproduced on EspressoBIN and Turris MOX: cd /sys/devices/system/cpu/cpufreq/policy0 echo powersave >scaling_governor echo performance >scaling_governor Running the mhz tool before this driver is loaded reports 1000 MHz, and after loading the driver and executing commands above the tool reports 800 MHz. The change of TBG clock selector is supposed to happen in function armada37xx_cpufreq_dvfs_setup. Before the function returns, it does this: parent = clk_get_parent(clk); clk_set_parent(clk, parent); The armada-37xx-periph clock driver has the .set_parent method implemented correctly for this, so if the method was actually called, this would work. But since the introduction of the common clock framework in commit b2476490ef11 ("clk: introduce the common clock..."), the clk_set_parent function checks whether the parent is actually changing, and if the requested new parent is same as the old parent (which is obviously the case for the code above), the .set_parent method is not called at all. This patch fixes this issue by filling the correct TBG clock selector directly in the armada37xx_cpufreq_dvfs_setup during the filling of other registers at the same address. But the determination of CPU TBG index cannot be done via the common clock framework, therefore we need to access the North Bridge Peripheral Clock registers directly in this driver.

2021-04-09thunderbolt: Hide authorized attribute if router does not support PCIe tunnelsMika Westerberg1-1/+14
With USB4 devices PCIe tunneling is optional so for device routers without PCIe upstream adapter it does not make much sense to expose the authorized attribute. For this reason hide it if PCIe tunneling is not supported by the device router.

In adf_create_ring, if the callee adf_init_ring() failed, the callee will free the ring->base_addr by dma_free_coherent() and return -EFAULT. Then adf_create_ring will goto err and the ring->base_addr will be freed again in adf_cleanup_ring(). My patch sets ring->base_addr to NULL after the first freed to avoid the double free.
