PR: 246867 Submitted by: Oskar Holmund (oskar.holmlund@ohdata.se) Differential Revision: https://reviews.freebsd.org/D25080 2020-06-18T23:31:56Z Emmanuel Vadot manu@FreeBSD.org 2020-06-18T23:31:56Z urn:sha1:a79dff004bc9964994cf58ae0ca87ae487813879 r358555: cpufreq_dt: Improve multiple opp support When looking for cpu with the same OPP starts from the root /cpus node so each instance of cpufreq_dt will now each cpu with the same operating point. Also test that the node we are testing have the property "device_type" set to be equal to "cpu". While here add more debug printfs (off by defaults). r358799: cpufreq_dt: Fix r358555 Before skipping the current cpu when trying to find the ones that have the same opp, record that this one have this opp. Reported by: mmel X-MFC-With: r358555 r358800: cpufreq: Unbreak build. 2020-03-04T20:30:11Z Emmanuel Vadot manu@FreeBSD.org 2020-03-04T20:30:11Z urn:sha1:26bf248c1be4c386a6e89f76a27e69818f4741d8 r355360: cpufreq_dt: Do not attach the device if the cpu isn't present If we boot with hw.ncpu=X (available on arm and arm64 at least) we shouldn't attach the cpufreq driver as cf_set_method will try to get the cpuid and it doesn't exists. This solves cpufreq panicing on RockChip RK3399 when booting with hw.ncpu=4 r355361: cpufreq_dt: Do not fetch again hw.ncpu MD code already set the global variable mp_ncpus according to the tunable hw.ncpu so use the global variable directly.

Typically, u-boot can set starting CPU frequency to any value. 2018-07-19T11:31:49Z Emmanuel Vadot manu@FreeBSD.org 2018-07-19T11:31:49Z urn:sha1:41a76289e601b4c6847f6f03ecf9acba75823528 Oppv2 add more flexibility on regulator value for the core voltage amongst other new thing. For now only shared opp table is supported as I don't have hardware with non-shared opp table.

For the use cases where number of elements is preferred introduce OF_getencprop_alloc_multi helper function that copies semantics of OF_getencprop_alloc prior to this change. This is to make OF_getencprop_alloc and OF_getencprop_alloc_multi function signatures consistent with OF_getencprop_alloc and OF_getencprop_alloc_multi. Functionality-wise this patch is mostly rename of OF_getencprop_alloc to OF_getencprop_alloc_multi except two calls in ofw_bus_setup_iinfo where 1 was used as a block size. 2017-11-27T14:52:40Z Pedro F.

The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. 2016-09-06T20:43:26Z Jared McNeill jmcneill@FreeBSD.org 2016-09-06T20:43:26Z urn:sha1:319336a943a5da19130b59cbaac73be19bf8a673 This driver supports two bindings: - cpufreq-dt: systems which share clock and voltage across all CPUs - arm_big_little_dt: systems which share clock and voltage across all CPUs in a single cluster Reviewed by: andrew, imp Relnotes: yes Differential Revision: https://reviews.freebsd.org/D7741 2013-02-26T18:30:47Z John Baldwin jhb@FreeBSD.org 2013-02-26T18:30:47Z urn:sha1:7ad65edee343f79be93a1ec098d38a7881609e02 southbridge and an Intel 82815_MC host bridge where the host bridge's revision is less than 5.
