These are the Top of the Rack 1U/2U/4U systems, equipped with Mellanox Comex card and with the switch board with Mellanox Spectrum-3 device. This class of devices can be equipped with two PS units for 1U/2U or with four PS units for 4U systems.

| * | | | | platform/mellanox: mlxreg-hotplug: Add support for new capability registerVadim Pasternak2020-01-131-0/+14

Such components could be for example the number of power units and interrupts related to these units. The motivation is to avoid adding a new code in the future in order to distinct between the systems type supported different number of the components like power supplies, FANs, ASICs, line cards.

It introduces more reset causes, which can be monitored after the reboots. - Setting and removing system VPD (EEPROM) hardware write protection. It allows to access VPD during production cycle and prevents VPD corruption on system in field. - Voltage regulator devices configuration update status and version. It allows to monitor configuration update status and current active version for such sort of devices. - PCIe ASIC reset disable - when set ASIC will go down upon PCIe root complex reset, otherwise ASIC will stay up during PCIe root complex reset. - System configuration Ids to provide system static topology identification, like system's static I2C topology, number and type of FPGA devices within the system and so on. Add the existing attribute for "iio" bank selection for system type "msn21xx". All the above attributes are exposed through "sysfs" by "mlxreg-io" driver.

Here uncore frequency controls RING/LLC(last-level cache) clocks. But MSR control is not always possible from the user space, so this driver provides a sysfs interface to set max and min frequency limits. This MSR 620H is a die scoped in multi-die system or package scoped in non multi-die systems. When this driver is loaded, a new directory is created under /sys/devices/system/cpu. For example on a two package Skylake server: $cd /sys/devices/system/cpu/intel_uncore_frequency $ls package_00_die_00 package_01_die_00 $ls package_00_die_00 max_freq_khz min_freq_khz initial_max_freq_khz initial_min_freq_khz $grep . * max_freq_khz:2400000 min_freq_khz:1200000 initial_max_freq_khz:2400000 initial_min_freq_khz:1200000 Here, initial_max_freq_khz and initial_min_freq_khz are read only attributes to show power up or initial values of max and min frequencies respectively. Other attributes are read-write, so that users can modify. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

Refusing to load leaves the fan at the BIOS default setting, which is "Off". The CPU's thermal throttling should protect the system from damage, but not-loading is really not the best fallback in this case. This commit fixes this by re-setting module-parameter values to their defaults if they are out of range, instead of failing the probe with -EINVAL.

Rx and Tx both take the console and tmfifo spinlock but in different order which causes potential deadlock. The fix is to use different tmfifo spinlock for Rx and Tx since they protect different resources and it's safe to split the lock.

The names and number of these IPs might differ from its previous platforms. The number of PCH IPs per platform is calculated based on PPFEAR_NUM_ENTRIES defined, where each entry represents a bucket (8 bits). The platform can support 'n' entries, but not necessarily all 'n * 8' IPs. Create platform dependent bitmap structures to specify the exact number, names of IPs while reusing the existing IPs. The changes in this patch are preparatory to accommodate future SoCs that might reuse the CNL/ICL PCH IPs, and to reflect the exact number of IPs with its names.

But when the last element is a termination marker, the comma could be harmful. Any new entries must be added before the terminator (and the comma would prevent the compiler from issuing a warning about an entry after the terminator).

The CPU's thermal throttling should protect the system from damage, but not-loading is really not the best fallback in this case. This commit fixes this by re-setting module-parameter values to their defaults if they are out of range, instead of failing the probe with -EINVAL.
