[PATCH 1/7] drm/i915/hwmon: Add HWMON infrastructure

[Badal Nilawar]

From: Dale B Stimson <dale.b.stimson@intel.com>

The i915 HWMON module will be used to expose voltage, power and energy
values for dGfx. Here we set up i915 hwmon infrastructure including i915
hwmon registration, basic data structures and functions.

v2:
  - Create HWMON infra patch (Ashutosh)
  - Fixed review comments (Jani)
  - Remove "select HWMON" from i915/Kconfig (Jani)
v3: Use hwm_ prefix for static functions (Ashutosh)
v4: s/#ifdef CONFIG_HWMON/#if IS_REACHABLE(CONFIG_HWMON)/ since the former
    doesn't work if hwmon is compiled as a module (Guenter)
v5: Fixed review comments (Jani)
v6: s/kzalloc/devm_kzalloc/ (Andi)

If we are using devm_kzalloc we might as well replace all the
hwmon_device_register_with_info's (in Patch 1 and 7) with
devm_hwmon_device_register_with_info and then i915_hwmon_unregister is just
this:

void i915_hwmon_unregister(struct drm_i915_private *i915)
{
        fetch_and_zero(&i915->hwmon);
}

Even the above statement is probably not needed but might as well retain it
for sanity. So this is a simple change.

Thanks.

[PATCH 3/7] drm/i915/hwmon: Power PL1 limit and TDP setting

[Badal Nilawar]

From: Dale B Stimson <dale.b.stimson@intel.com>

Use i915 HWMON to display/modify dGfx power PL1 limit and TDP setting.

v2:
  - Fix review comments (Ashutosh)
  - Do not restore power1_max upon module unload/load sequence
    because on production systems modules are always loaded
    and not unloaded/reloaded (Ashutosh)
  - Fix review comments (Jani)
  - Remove endianness conversion (Ashutosh)
v3: Add power1_rated_max (Ashutosh)
v4:
  - Use macro HWMON_CHANNEL_INFO to define power channel (Guenter)
  - Update the date and kernel version in Documentation (Badal)
v5: Use hwm_ prefix for static functions (Ashutosh)
v6: Fix review comments (Ashutosh)
v7:
  - Define PCU_PACKAGE_POWER_SKU for DG1,DG2 and move
    PKG_PKG_TDP to intel_mchbar_regs.h (Anshuman)
  - KernelVersion: 6.2, Date: February 2023 in doc (Tvrtko)

[PATCH 3/7] drm/i915/hwmon: Power PL1 limit and TDP setting

[Badal Nilawar]

From: Dale B Stimson <dale.b.stimson@intel.com>

Use i915 HWMON to display/modify dGfx power PL1 limit and TDP setting.

v2:
  - Fix review comments (Ashutosh)
  - Do not restore power1_max upon module unload/load sequence
    because on production systems modules are always loaded
    and not unloaded/reloaded (Ashutosh)
  - Fix review comments (Jani)
  - Remove endianness conversion (Ashutosh)
v3: Add power1_rated_max (Ashutosh)
v4:
  - Use macro HWMON_CHANNEL_INFO to define power channel (Guenter)
  - Update the date and kernel version in Documentation (Badal)
v5: Use hwm_ prefix for static functions (Ashutosh)
v6: Fix review comments (Ashutosh)
v7:
  - Define PCU_PACKAGE_POWER_SKU for DG1,DG2 and move
    PKG_PKG_TDP to intel_mchbar_regs.h (Anshuman)
  - KernelVersion: 6.2, Date: February 2023 in doc (Tvrtko)

[PATCH 5/7] drm/i915/hwmon: Expose card reactive critical power

[Badal Nilawar]

From: Ashutosh Dixit <ashutosh.dixit@intel.com>

Expose the card reactive critical (I1) power. I1 is exposed as
power1_crit in microwatts (typically for client products) or as
curr1_crit in milliamperes (typically for server).

v2: Add curr1_crit functionality (Ashutosh)
v3: Use HWMON_CHANNEL_INFO to define power1_crit, curr1_crit (Badal)
v4: Use hwm_ prefix for static functions (Ashutosh)
v5: KernelVersion: 6.2, Date: February 2023 in doc (Tvrtko)

[Intel-gfx] [PATCH 5/7] drm/i915/hwmon: Expose card reactive critical power

[Badal Nilawar]

From: Ashutosh Dixit <ashutosh.dixit@intel.com>

Expose the card reactive critical (I1) power. I1 is exposed as
power1_crit in microwatts (typically for client products) or as
curr1_crit in milliamperes (typically for server).

v2: Add curr1_crit functionality (Ashutosh)
v3: Use HWMON_CHANNEL_INFO to define power1_crit, curr1_crit (Badal)
v4: Use hwm_ prefix for static functions (Ashutosh)
v5: KernelVersion: 6.2, Date: February 2023 in doc (Tvrtko)

[PATCH 6/7] drm/i915/hwmon: Expose power1_max_interval

[Badal Nilawar]

From: Ashutosh Dixit <ashutosh.dixit@intel.com>

Expose power1_max_interval, that is the tau corresponding to PL1. Some bit
manipulation is needed because of the format of PKG_PWR_LIM_1_TIME in
GT0_PACKAGE_RAPL_LIMIT register (1.x * power(2,y)).

v2: Update date and kernel version in Documentation (Badal)
v3: Cleaned up hwm_power1_max_interval_store() (Badal)
v4:
  - Fixed review comments (Anshuman)
  - In hwm_power1_max_interval_store() get PKG_MAX_WIN from
    pkg_power_sku when it is valid (Ashutosh)
  - KernelVersion: 6.2, Date: February 2023 in doc (Tvrtko)

[PATCH 6/7] drm/i915/hwmon: Expose power1_max_interval

[Badal Nilawar]

From: Ashutosh Dixit <ashutosh.dixit@intel.com>

Expose power1_max_interval, that is the tau corresponding to PL1. Some bit
manipulation is needed because of the format of PKG_PWR_LIM_1_TIME in
GT0_PACKAGE_RAPL_LIMIT register (1.x * power(2,y)).

v2: Update date and kernel version in Documentation (Badal)
v3: Cleaned up hwm_power1_max_interval_store() (Badal)
v4:
  - Fixed review comments (Anshuman)
  - In hwm_power1_max_interval_store() get PKG_MAX_WIN from
    pkg_power_sku when it is valid (Ashutosh)
  - KernelVersion: 6.2, Date: February 2023 in doc (Tvrtko)

I think let's change the above sentence to: "Expose power1_max_interval,
that is the tau corresponding to PL1, as a custom hwmon attribute".

This is the only custom attribute we are exposing so better to mention this
in the commit message I think.

Thanks.

[PATCH 6/7] drm/i915/hwmon: Expose power1_max_interval

[Ashutosh Dixit]

Expose power1_max_interval, that is the tau corresponding to PL1, as a
custom hwmon attribute. Some bit manipulation is needed because of the

[PATCH 6/7] drm/i915/hwmon: Expose power1_max_interval

[Ashutosh Dixit]

Expose power1_max_interval, that is the tau corresponding to PL1, as a
custom hwmon attribute. Some bit manipulation is needed because of the
format of PKG_PWR_LIM_1_TIME in
GT0_PACKAGE_RAPL_LIMIT register (1.x * power(2,y)).

v2: Update date and kernel version in Documentation (Badal)
v3: Cleaned up hwm_power1_max_interval_store() (Badal)
v4:
  - Fixed review comments (Anshuman)
  - In hwm_power1_max_interval_store() get PKG_MAX_WIN from
    pkg_power_sku when it is valid (Ashutosh)
  - KernelVersion: 6.2, Date: February 2023 in doc (Tvrtko)
v5: On some of the DGFX setups it is seen that although pkg_power_sku
    is valid the field PKG_WIN_MAX is not populated. So it is
    decided to stick to default value of PKG_WIN_MAX (Ashutosh)
v6: Change contact to intel-gfx (Rodrigo)
    Fixed variable types in hwm_power1_max_interval_store (Andi)
    Documented PKG_MAX_WIN_DEFAULT (Andi)
    Removed else in hwm_attributes_visible (Andi)

[PATCH 6/7] drm/i915/hwmon: Expose power1_max_interval

[Badal Nilawar]

From: Ashutosh Dixit <ashutosh.dixit@intel.com>

Expose power1_max_interval, that is the tau corresponding to PL1, as a
custom hwmon attribute. Some bit manipulation is needed because of the
format of PKG_PWR_LIM_1_TIME in
GT0_PACKAGE_RAPL_LIMIT register (1.x * power(2,y)).

v2: Update date and kernel version in Documentation (Badal)
v3: Cleaned up hwm_power1_max_interval_store() (Badal)
v4:
  - Fixed review comments (Anshuman)
  - In hwm_power1_max_interval_store() get PKG_MAX_WIN from
    pkg_power_sku when it is valid (Ashutosh)
  - KernelVersion: 6.2, Date: February 2023 in doc (Tvrtko)
v5: On some of the DGFX setups it is seen that although pkg_power_sku
    is valid the field PKG_WIN_MAX is not populated. So it is
    decided to stick to default value of PKG_WIN_MAX (Ashutosh)

[PATCH 6/7] drm/i915/hwmon: Expose power1_max_interval

[Badal Nilawar]

From: Ashutosh Dixit <ashutosh.dixit@intel.com>

Expose power1_max_interval, that is the tau corresponding to PL1, as a
custom hwmon attribute. Some bit manipulation is needed because of the
format of PKG_PWR_LIM_1_TIME in
GT0_PACKAGE_RAPL_LIMIT register (1.x * power(2,y)).

v2: Update date and kernel version in Documentation (Badal)
v3: Cleaned up hwm_power1_max_interval_store() (Badal)
v4:
  - Fixed review comments (Anshuman)
  - In hwm_power1_max_interval_store() get PKG_MAX_WIN from
    pkg_power_sku when it is valid (Ashutosh)
  - KernelVersion: 6.2, Date: February 2023 in doc (Tvrtko)
v5: On some of the DGFX setups it is seen that although pkg_power_sku
    is valid the field PKG_WIN_MAX is not populated. So it is
    decided to stick to default value of PKG_WIN_MAX (Ashutosh)

[PATCH 6/7] drm/i915/hwmon: Expose power1_max_interval

[Badal Nilawar]

From: Ashutosh Dixit <ashutosh.dixit@intel.com>

Expose power1_max_interval, that is the tau corresponding to PL1. Some bit
manipulation is needed because of the format of PKG_PWR_LIM_1_TIME in
GT0_PACKAGE_RAPL_LIMIT register (1.x * power(2,y)).

v2: Update date and kernel version in Documentation (Badal)
v3: Cleaned up hwm_power1_max_interval_store() (Badal)

AFAIU we need to read r from PACKAGE_POWER_SKU reg untill unless it has

The platform on which I tried had an incorrect value (that is why I didn't
read it from PACKAGE_POWER_SKU) but let me investigate it some more for
other platforms and get back.

Yes this is the same _PACKAGE_POWER_SKU register so should get fixed when
we add it in Patch 3.

I checked, the value is correct on DG1/DG2 which have a valid
PACKAGE_POWER_SKU (XEHPSDV does not have a valid
PACKAGE_POWER_SKU). Therefore the one line above should be replaced with
the code below:

	if (i915_mmio_reg_valid(hwmon->rg.pkg_power_sku))
		with_intel_runtime_pm(ddat->uncore->rpm, wakeref)
			r = intel_uncore_read64(ddat->uncore, hwmon->rg.pkg_power_sku);
	else
		r = FIELD_PREP(PKG_MAX_WIN, PKG_MAX_WIN_DEFAULT);

Looks like PCU_PACKAGE_POWER_SKU for DG1/DG2 will need to be declared in

[PATCH 6/7] drm/i915/hwmon: Expose power1_max_interval

[Badal Nilawar]

From: Ashutosh Dixit <ashutosh.dixit@intel.com>

Expose power1_max_interval, that is the tau corresponding to PL1. Some bit
manipulation is needed because of the format of PKG_PWR_LIM_1_TIME in
GT0_PACKAGE_RAPL_LIMIT register (1.x * power(2,y)).

v2: Update date and kernel version in Documentation (Badal)
v3: Cleaned up hwm_power1_max_interval_store() (Badal)

[PATCH 0/7] drm/i915: Add HWMON support

[Badal Nilawar]

This series adds the HWMON support for DGFX

v2:
  - Reorganized series. Created first patch as infrastructure patch
    followed by feature patches. (Ashutosh)
  - Fixed review comments (Jani)
  - Fixed review comments (Ashutosh)

v3:
  - Fixed review comments from Guenter
  - Exposed energy inferface as standard hwmon interface (Ashutosh)
  - For power interface added entries for critical power and maintained
    standard interface for all the entries except 
    power1_max_interval
  - Extended support for XEHPSDV (Ashutosh)

[PATCH 6/7] drm/i915/hwmon: Expose power1_max_interval

[Badal Nilawar]

From: Ashutosh Dixit <ashutosh.dixit@intel.com>

Expose power1_max_interval, that is the tau corresponding to PL1. Some bit
manipulation is needed because of the format of PKG_PWR_LIM_1_TIME in
GT0_PACKAGE_RAPL_LIMIT register (1.x * power(2,y)).

v2: Update date and kernel version in Documentation (Badal)
