● Raspberry Pi OS Bullseyeは Raspberry Pi 4 Model Bで 1.8GHzの動作をサポートします

 ラズパイ4Bで 1.8GHz動作が可能 config.txtに arm_freq=1800を追加、ただし動作対象の条件有り。

 2021/11/28追記 下記のベンチマークの追試確認で、config.txtに arm_freq=1800を追加していない状態でも 1.8GHzで動作している事が確認できました。(= 何もしなくても勝手に 1.8GHz動作になる)

Raspberry Pi OS
 Debian version 11 bullseye

Bullseye - the new version of Raspberry Pi OS

Bullseye bonus: 1.8GHz Raspberry Pi 4

●ラズパイ4Bの 1.8GHzの動作対象の条件

 基板の電源部分が下記になっている事。
 ※ 「基盤」は間違いです。板 Board 「基板」です。

ラズパイ4B 8GB全部 1.8GHzの動作対象
ラズパイ4B 4GB最近のロットが 1.8GHzの動作対象
ラズパイ4B 2GB最近のロットが 1.8GHzの動作対象
ラズパイ4B 1GB全部動作対象外

●ラズパイ4Bの 1.8GHzの動作対象の確認方法(目視)

・1.8GHzの動作対象

● Raspberry Piの動作周波数を確認する方法 vcgencmd

 動作中の「その時」の動作周波数を表示します。
● Raspberry Piに負荷が有る時は 1.5GHz
$ vcgencmd measure_clock arm
frequency(48)=1500345728
※ config.txtに arm_freq=1500を追加

● Raspberry Piに負荷が無い時は 600MHz
$ vcgencmd measure_clock arm
frequency(48)=600117184

● Raspberry Piに負荷が有る時は 1.8GHz
$ vcgencmd measure_clock arm
frequency(48)=1800457088
※ config.txtに arm_freq=1800を追加
※ config.txtに arm_freq=1800を追加していない時も 1.8GHzで動作していました

$ watch vcgencmd measure_clock arm
 watchコマンドで連続で表示します(観察時に便利)


● Raspberry Pi 4Bで 1.5GHzと 1.8GHzのベンチマーク比較

 /boot/config.txtに下記の行を追加(編集)する。
$ sudo nano /boot/config.txt

# 1.5GHz動作の場合
arm_freq=1500

# 1.8GHz動作の場合
arm_freq=1800

# 2.0GHz動作の場合
arm_freq=2000

# 2.2GHz動作の場合
arm_freq=2200

 Linuxのベンチマークで標準的な UnixBenchを使います。

config.txtは未編集config.txtに arm_freq=1800を追加
1.5GHz?1.8GHzUP率(理論値 20% UP)
1 core319.0321.0UPしていないなぁ?
4 core854.8866.0UPしていないなぁ?
※ config.txtに arm_freq=1800を追加しなくても 1.8GHzで動いていた説?
 ビンゴ! config.txtに arm_freq=1800を追加していない時も 1.8GHzで動作していました!!

●正しくは下記の表

 明示的に arm_freq=1500を追加を追加して 1.5GHzでのベンチマークを測定します。
config.txtに arm_freq=1500を追加config.txtに arm_freq=1800を追加config.txtは未編集
1.5GHz1.8GHz1.8GHzUP率(理論値 20% UP)
1 core268.4319.0321.019.6% UP
4 core770.7854.8866.012.3% UP
 とりあえず、そこそこ納得のいく測定結果が得られました。

 File Copy等の I/O周りのボトルネックが有るので 4 coreの成績が CPUの動作速度に比例していないと思われる。

● Raspberry Piで円周率を 1億桁計算してみる

円周率を1億桁計算しました! ― その試行錯誤の詳しい経緯と結果 ー

 ここの内容をそのまま実行します。

sudo apt-get install libgmp3-dev

# Binary Splitting method によるChudnovsky実装
# 再帰でガーーーーッって行く感じ, 割と直感的に書きました. 以下のコードがこのエントリーの最終的なコードです. ベンチを取るときはこのコードを使用してください.
# のソースコードを入力する

● Raspberry Pi OS Bullseyeの注意事項

 Raspicam apps, the Picamera Python library, or OMXPlayerが Bullseyeでは動きません。
 Python Picamera moduleを Bullseyeで使いたい場合は raspi-configで Legacy Camera Enable/disable legacy camera supportを「有効」にします。
sudo raspi-config
 3  Interface Options
 I1 Legacy Camera Enable/disable legacy camera support

Getting started with the Camera Module
Raspberry Pi Camera Module - Operating System notice
The Python Picamera module is currently not, by default, compatible with the latest version of Raspberry Pi OS (called Bullseye).

To use the Picamera module, you will need to enable legacy support for the camera.


● Raspberry Pi OS Bullseyeは過去のアプリが使えなくなっているので Busterが Legacyとして Raspberry Pi公式が継続サポート
