+# ipu6-softisp
+
+This code adds support for the ipu6 webcams via libcamera, based on the work in
+https://copr.fedorainfracloud.org/coprs/jwrdegoede/ipu6-softisp/.
+
+It's supposed to be included in your NixOS configuration imports, and will:
+
+ - Add some patches to your kernel, which should apply on 6.7.x
+ - Add the `ipu6-camera-bins` firmware (still needed)
+ - Enable some kernel config options
+ - Add an udev rule so libcamera can do DMABUF things
+ - Override `services.pipewire.package` and
+   `services.pipewire.wireplumber.package` to use a pipewire built with a libcamera
+   with support for this webcam.
+
+Please make sure you don't have any of the `hardware.ipu6` options still
+enabled, as they use the closed-source userspace stack and will conflict.
+
+The testing instructions from
+https://copr.fedorainfracloud.org/coprs/jwrdegoede/ipu6-softisp/ still apply.
+
+`qcam` can be found in `libcamera-qcam` (pending on
+https://github.com/NixOS/nixpkgs/pull/284964 to trickle into master).
+
+Thanks to Hans de Goede for helping me bringing this up, as well as to
+puckipedia for sorting out some pipewire-related confusion.

+outputSizes, and then the adjusted configuration won't be

+DmaHeap class is useful outside the RPi pipeline handler too.

+Move dma_heaps.h and dma_heaps.cpp to common directories. Update

+Subject: [PATCH 03/25] libcamera: dma_heaps: extend DmaHeap class to support
+ system heap
+
+Add an argument to the constructor to specify dma heaps type(s)
+to use. Can be DmaHeapFlag::Cma and/or DmaHeapFlag::System.
+By default DmaHeapFlag::Cma is used. If both DmaHeapFlag::Cma and
+DmaHeapFlag::System are set, CMA heap is tried first.

+From ca3bb6ddf5307537aa05e43d3ec1ff7ffdc0efed Mon Sep 17 00:00:00 2001
+From: Hans de Goede <hdegoede@redhat.com>
+Date: Thu, 7 Dec 2023 13:30:27 +0100
+Subject: [PATCH 07/25] libcamera: software_isp: Add SwStats base class
+
+Add a virtual base class for CPU based software statistics gathering
+implementations.
+
+The idea is for the implementations to offer a configure function +
+functions to gather statistics on a line by line basis. This allows
+CPU based software debayering to call into interlace debayering and
+statistics gathering on a line by line bases while the input data
+is still hot in the cache.
+
+This base class also allows the user of an implementation to specify
+a window over which to gather statistics instead of processing the
+whole frame; and it allows the implementation to choose to only
+process 1/2, 1/4th, etc. of the lines instead of processing all
+lines (in the window) by setting y_skip_mask_ from configure().
+Skipping columns is left up the line-processing functions provided
+by the implementation.
+
+Doxygen documentation by Dennis Bonke.

+Subject: [PATCH 13/25] libcamera: software_isp: add Simple SoftwareIsp
+ implementation
+
+The implementation of SoftwareIsp handles creation of Soft IPA
+and interactions with it, so that the pipeline handler wouldn't
+need to care about the Soft IPA.

+Doxygen documentation by Dennis Bonke.

+Subject: [PATCH 14/25] libcamera: pipeline: simple: rename converterBuffers_
+ and related vars
+
+The converterBuffers_ and the converterQueue_ are not that specific
+to the Converter, and could be used by another entity doing the format
+conversion.
+
+Rename converterBuffers_, converterQueue_, and useConverter_ to
+conversionBuffers_, conversionQueue_ and useConversion_ to
+disassociate them from the Converter.

+Subject: [PATCH 15/25] libcamera: pipeline: simple: enable use of Soft ISP and
+ Soft IPA
+
+To enable the Simple Soft ISP and Soft IPA for simple pipeline handler
+configure the build with:
+  -Dpipelines=simple/simple -Dipas=simple/simple
+
+If the pipeline uses Converter, Soft ISP and Soft IPA aren't
+available.
+
+Configuring the build with just:
+  -Dpipelines=simple
+makes it to work like before - Soft ISP and Soft IPA aren't used.

++Software ISP benchmarking
++=========================
++
++The Software ISP is paricular sensitive to performance regressions
++therefor it is a good idea to always benchmark the Software ISP
++before and after making changes to it and ensure that there are
++no performance regressions.
++
++DebayerCpu class builtin benchmark
++----------------------------------
++
++The DebayerCpu class has a builtin benchmark. This benchmark
++measures the time spend on processing (collecting statistics
++and debayering) only, it does not measure the time spend on
++capturing or outputting the frames.
++
++The builtin benchmark always runs. So this can be used by simply
++running "cam" or "qcam" with a pipeline using the Software ISP.
++
++When it runs it will skip measuring the first 30 frames to
++allow the caches and the CPU temperature (turbo-ing) to warm-up
++and then it measures 30 fps and shows the total and per frame
++processing time using an info level log message:
++
++.. code-block::
++
++   INFO Debayer debayer_cpu.cpp:907 Processed 30 frames in 244317us, 8143 us/frame
++
++To get stable measurements it is advised to disable any other processes which
++may cause significant CPU usage (e.g. disable wifi, bluetooth and browsers).
++When possible it is also advisable to disable CPU turbo-ing and
++frequency-scaling.
++
++For example when benchmarking on a Lenovo ThinkPad X1 Yoga Gen 8, with
++the charger plugged in, the CPU can be fixed to run at 2 GHz using:
++
++.. code-block::
++
++   sudo x86_energy_perf_policy --turbo-enable 0
++   sudo cpupower frequency-set -d 2GHz -u 2GHz
++
++with these settings the builtin bench reports a processing time of ~7.8ms/frame
++on this laptop for FHD SGRBG10 (unpacked) bayer data.
++
++Measuring power consumption
++---------------------------
++
++Since the Software ISP is often used on mobile devices it is also
++important to measure power consumption and ensure that that does
++not regress.
++
++For example to measure power consumption on a Lenovo ThinkPad X1 Yoga Gen 8
++it needs to be running on battery and it should be configured with its
++platform-profile (/sys/firmware/acpi/platform_profile) set to balanced and
++with its default turbo and frequency-scaling behavior to match real world usage.
++
++Then start qcam to capture a FHD picture at 30 fps and position the qcam window
++so that it is fully visible. After this run the following command to monitor
++the power consumption:
++
++.. code-block::
++
++   watch -n 10 cat /sys/class/power_supply/BAT0/power_now /sys/class/hwmon/hwmon6/fan?_input
++
++Note this not only measures the power consumption in ųW it also monitors
++the speed of this laptop's 2 fans. This is important because depending on
++the ambient temperature the 2 fans may spin up while testing and this
++will cause an additional power consumption of approx. 0.5W messing up
++the measurement.
++
++After starting qcam + the watch command let the laptop sit without using
++it for 2 minutes for the readings to stabilize. Then check that the fans
++have not turned on and manually take a couple of consecutive power readings
++and avarage these.
++
++On the example Lenovo ThinkPad X1 Yoga Gen 8 laptop this results in
++a measured power consumption of approx. 13W while running qcam versus
++approx. 4-5W while setting idle with its OLED panel on.

+
+pipewire + firefox default to what looks like 640x480 if we export
+the entire supported cropping range. Hardcode 720p as minsize for now.
