Below are the conditions result in NvRmMemHandle creation - 1) VA: RO and Attr: RW - Don't create NvMap Handle 2) VA: RO and Attr: RO - Create NvMap Handle and set dma_buf_fd as RO 3) VA: RW and Attr: RO - Create NvMap Handle and set dma_buf_fd as RO 4) Mixed VA: RO + RW and Attr: RO - Create NvMap Handle with dma_buf_fd as RO for the whole buffer 5) Mixed VA: RO + RW and Attr: RW - Don't Create NvMap Handle If few pages of the buffer is set as RO and rest as RW, multiple vma are created and vma->end and vma->start doesn't differ by the buffer size, passed to create handle from VA. Hence remove the check. Anyway the check is done in get_user_pages. The change sets dma_buf_fd as RW/RO so that other process should fetch the access permission just by reading f_mode of dma_buf_fd.

* therm-fan-est: Add support for Tmargin to drive fanmkarthik2020-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Why? Tmargin method of fan control allows multiple groups of therma-fan-est devices temperatures to be considered for the fan control algorithm/fan curve. The limitation of the existing max temp algorithm in therm-fan-est driver is that devices with different fan curves cannot be accomodated in the driver. In case, there are multple fan curves, the device which has the steepest curve wins the algoritm. Hence, taking the temperatures as a reference from their respective critical temperatures and using that value to drive the fan will help in accomodating both the devices' fan curves. How? * Calculate the effective crit temp of all the thermal zones during probe. * In the polling cycles, calculate the effective temperatures of the individual groups and use the tmargin formula to calculate the current temperature. * Since the Tmargin temp trip values are in reverse order, we need to use the reverse order in the pwm-fan dt profile. * The hysterysis is subtracted from the temp in cooling scenario to avoid frequent switching at trip temps. Since the tmargin trip values are taken in the decending order, hysterysis temps in dt should be given as negative values.

There is no tachometer rpm read back to check if the thermal performance is as expected. This change aims to add the rpm offsets necessary to maintain the desired fan rpm. How? A new work queue is added which gets the pwm fan rpm and checks the same for a rpm diff tolerance value. In case the tolerance value is exceeded, the next pwm corresponding to the next rpm ramp index is written to the pwm controller.

* thermal: Kernel driver for OC event handlingMantravadi Karthik2020-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Why? In case of an OC(Over Current) event in Tegra SOC, BPMP gets an interrupt indicating the same. However, there is no indication to ccplex and userspace about the same. This driver provides the interface between BPMP OC implementation and userspace. How? Once there is an EDP OC interrupt to BPMP, BPMP writes to a Shared mailbox register dedicated for BPMP and CCPLEX communication for EDP OC. Once the interrupt is received, Kernel reads the OC status registers to realize the state of the EDP OC HW. The kernel driver provides interfaces for Userspace to poll for the status/interrupts count.
