powercap: Add Hygon Fam18h RAPL support

2021-03-18T18:42:23Z

Enable Hygon Fam18h RAPL support for the power capping framework. Signed-off-by: Pu Wen Signed-off-by: Rafael J. Wysocki

powercap/drivers/dtpm: Add the experimental label to the option description

2021-03-01T16:43:29Z

The DTPM framework will evolve in the next cycles. Let's add a temporary EXPERIMENTAL tag to the option so users will be aware the API may change over time. Signed-off-by: Daniel Lezcano Signed-off-by: Rafael J. Wysocki

powercap/drivers/dtpm: Fix root node initialization

2021-03-01T16:43:29Z

The root node is not set to NULL when the dtpm root node is removed. Consequently, it is not possible to create a new root as it is already set. Set the root node to NULL when the last node is removed. Signed-off-by: Daniel Lezcano Signed-off-by: Rafael J. Wysocki

powercap: intel_rapl: Use topology interface in rapl_init_domains()

2021-02-12T15:53:01Z

It's not a good idea to access the phys_proc_id of cpuinfo directly. Use topology_physical_package_id(cpu) instead. Signed-off-by: Yunfeng Ye [ rjw: Changelog edits ] Signed-off-by: Rafael J. Wysocki

powercap: intel_rapl: Use topology interface in rapl_add_package()

2021-02-12T15:53:01Z

It's not a good idea to access phys_proc_id and cpu_die_id directly. Use topology_physical_package_id(cpu) and topology_die_id(cpu) instead. Signed-off-by: Yunfeng Ye [ rjw: Changelog edits ] Signed-off-by: Rafael J. Wysocki

powercap/intel_rapl: add support for AlderLake Mobile

2021-01-27T18:26:47Z

Add intel_rapl support for the AlderLake Mobile platform. Signed-off-by: Zhang Rui Signed-off-by: Rafael J. Wysocki

powercap/drivers/dtpm: Fix size of object being allocated

2021-01-07T17:16:03Z

The kzalloc allocation for dtpm_cpu is currently allocating the size of the pointer and not the size of the structure. Fix this by using the correct sizeof argument. Addresses-Coverity: ("Wrong sizeof argument") Fixes: 0e8f68d7f048 ("powercap/drivers/dtpm: Add CPU energy model based support") Signed-off-by: Colin Ian King Acked-by: Daniel Lezcano Signed-off-by: Rafael J. Wysocki

powercap/drivers/dtpm: Fix an IS_ERR() vs NULL check

2021-01-07T17:13:51Z

The powercap_register_control_type() function never returns NULL, it returns error pointers on error so update this check. Fixes: a20d0ef97abf ("powercap/drivers/dtpm: Add API for dynamic thermal power management") Signed-off-by: Dan Carpenter Acked-by: Daniel Lezcano Signed-off-by: Rafael J. Wysocki

powercap/drivers/dtpm: Fix some missing unlock bugs

2021-01-07T17:13:51Z

We need to unlock on these paths before returning. Fixes: a20d0ef97abf ("powercap/drivers/dtpm: Add API for dynamic thermal power management") Signed-off-by: Dan Carpenter Acked-by: Daniel Lezcano Signed-off-by: Rafael J. Wysocki

powercap/drivers/dtpm: Fix a double shift bug

2021-01-07T17:13:51Z

The DTPM_POWER_LIMIT_FLAG is used for test_bit() etc which take a bit number so it should be bit 0. But currently it's set to BIT(0) then that is double shifted equivalent to BIT(BIT(0)). This doesn't cause a run time problem because it's done consistently.
