2023-07-27hwmon: (k10temp) Enable AMD3255 Proc to show negative temperatureBaskaran Kannan
Industrial processor i3255 supports temperatures -40 deg celcius to 105 deg Celcius. The current implementation of k10temp_read_temp rounds off any negative temperatures to '0'. To fix this, the following changes have been made. A flag 'disp_negative' is added to struct k10temp_data to support AMD i3255 processors. Flag 'disp_negative' is set if 3255 processor is found during k10temp_probe. Flag 'disp_negative' is used to determine whether to round off negative temperatures to '0' in k10temp_read_temp.

2020-12-22hwmon: (k10temp) Remove support for displaying voltage and current on Zen CPUsGuenter Roeck
Voltages and current are reported by Zen CPUs. However, the means to do so is undocumented, changes from CPU to CPU, and the raw data is not calibrated. Calibration information is available, but again not documented. This results in less than perfect user experience, up to concerns that loading the driver might possibly damage the hardware (by reporting out-of range voltages). Effectively support for reporting voltages and current is not maintainable. Drop it. Cc: Artem S.

2020-09-23hwmon: (k10temp) Take out debugfs codeGuenter Roeck
The debugfs code was intended to aid figuring out functionality of undocumented registers. Turns out that wasn't very helpful, since register locations change too much between AMD chip revisions, and the data isn't really valuable for chips where it isn't already supported. On top of that, its existence has been used as argument for providing pseudo-API debugfs functions in other drivers. So let's just take it out. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2020-03-08hwmon: (k10temp) Swap Tdie and Tctl on Family 17h CPUsGuenter Roeck
Traditionally, the temperature displayed by k10temp was Tctl. On Family 17h CPUs, Tdie was displayed instead. To reduce confusion, Tctl was added later as second temperature. This resulted in Tdie being reported as temp1_input, and Tctl as temp2_input. This is different to non-Ryzen CPUs, where Tctl is displayed as temp1_input. Swap temp1_input and temp2_input on Family 17h CPUs, such that Tctl is now reported as temp1_input and Tdie is reported as temp2_input, to align with other CPUs, streamline the code, and make it less confusing. Coincidentally, this also aligns the code with its documentation, which states that Tdie is reported as temp2_input. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2020-01-23hwmon: (k10temp) Display up to eight sets of CCD temperaturesGuenter Roeck
In HWiNFO, we see support for Tccd1, Tccd3, Tccd5, and Tccd7 temperature sensors on Zen2 based Threadripper CPUs. Checking register maps on Threadripper 3970X confirms SMN register addresses and values for those sensors. Register values observed in an idle system: 0x059950: 00000000 00000abc 00000000 00000ad8 0x059960: 00000000 00000ade 00000000 00000ae4 Under load: 0x059950: 00000000 00000c02 00000000 00000c14 0x059960: 00000000 00000c30 00000000 00000c22 More analysis shows that EPYC CPUs support up to 8 CCD temperature sensors. EPYC 7601 supports three CCD temperature sensors. Unlike Zen2 CPUs, the register space in Zen1 CPUs supports a maximum of four sensors, so only search for a maximum of four sensors on Zen1 CPUs. On top of that, in thm_10_0_sh_mask.h in the Linux kernel, we find definitions for THM_DIE{1-3}_TEMP__VALID_MASK, set to 0x00000800, as well as matching SMN addresses. This lets us conclude that bit 11 of the respective registers is a valid bit. With this assumption, the temperature offset is now 49 degrees C. This conveniently matches the documented temperature offset for Tdie, again suggesting that above registers indeed report temperatures sensor values. Assume that bit 11 is indeed a valid bit, and add support for the additional sensors. With this patch applied, output from 3970X (idle) looks as follows: k10temp-pci-00c3 Adapter: PCI adapter Tdie: +55.9°C Tctl: +55.9°C Tccd1: +39.8°C Tccd3: +43.8°C Tccd5: +43.8°C Tccd7: +44.8°C Tested-by: Michael Larabel <michael@phoronix.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2019-09-03hwmon: (k10temp) Add support for AMD family 17h, model 70h CPUsMarcel Bocu
It would seem like model 70h is behaving in the same way as model 30h, so let's just add the new F3 PCI ID to the list of compatible devices. Unlike previous Ryzen/Threadripper, Ryzen gen 3 processors do not need temperature offsets anymore. This has been reported in the press and verified on my Ryzen 3700X by checking that the idle temperature reported by k10temp is matching the temperature reported by the firmware. Vicki Pfau sent an identical patch after I checked that no-one had written this patch. I would have been happy about dropping my patch but unlike for his patch series, I had already Cc:ed the x86 people and they already reviewed the changes. Since Vicki has not answered to any email after his initial series, let's assume she is on vacation and let's avoid duplication of reviews from the maintainers and merge my series. To acknowledge Vicki's anteriority, I added her S-o-b to the patch. v2, suggested by Guenter Roeck and Brian Woods: - rename from 71h to 70h Signed-off-by: Vicki Pfau <vi@endrift.com> Signed-off-by: Marcel Bocu <marcel.p.bocu@gmail.com> Tested-by: Marcel Bocu <marcel.p.bocu@gmail.com> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Ingo Molnar <mingo@redhat.com> Cc: Borislav Petkov <bp@alien8.de> Cc: "H.

2018-12-16hwmon: (k10temp) Add Hygon Dhyana supportPu Wen
Add support for Hygon Dhyana family 18h processor for k10temp to get the temperature. As Hygon Dhyana shares the same function interface with AMD family 17h, so add Hygon PCI Vendor ID and reuse the code path of AMD.

Add support for AMD family 17h model 30h processors for k10temp. Model 30h is functionally the same as model 01h processors (as far as k10temp is concerned), just the PCI device IDs need to be updated.

2018-10-10hwmon: (k10temp) Support all Family 15h Model 6xh and Model 7xh processorsGuenter Roeck
BIOS developer guides refer to Family 15h Models 60h-6fh and Family 15h Models 70h-7fh. So far the driver only checked for Models 60h and 70h. However, there are now processors with other model numbers in the same families. Example is A10-9620P family 15h model 65h. Follow the developer guides and mask the lower 4 bit of the model number to determine the registers to use for reading temperatures and temperature limits.

2018-08-09hwmon: k10temp: Support Threadripper 2920X, 2970WX; simplify offset tableGuenter Roeck
All announced Threadripper 29xx models have a temperature offset of 27 degrees C. Simplify temperature offset table to match all 29xx Threadripper models with a single entry. Also simplify the table to match all 19xx Threadripper models with a single entry. This effectively drops entries for Threadripper 1910/1920/1950 which never saw the light of day.

The function get_raw_temp is local to the source and does not need to be in global scope, so make it static.

2018-05-21hwmon: (k10temp) Display both Tctl and TdieGuenter Roeck
On some AMD CPUs, there is a different between the die temperature (Tdie) and the reported temperature (Tctl). Tdie is the real measured temperature, and Tctl is used for fan control. Lets report both for affected CPUs. Tested-by: Gabriel Craciunescu <nix.or.die@gmail.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2018-05-13hwmon: (k10temp) Use API function to access System Management NetworkGuenter Roeck
The SMN (System Management Network) on Family 17h AMD CPUs is also accessed from other drivers, specifically EDAC. Accessing it directly is racy. On top of that, accessing the SMN through root bridge 00:00 is wrong on multi-die CPUs and may result in reading the temperature from the wrong die. Use available API functions to fix the problem. For this to work, add dependency on AMD_NB. Also change the Raven Ridge PCI device ID to point to Data Fabric Function 3, since this ID is used by the API functions to find the CPU node.
