+Date: Tue, 22 Nov 2022 17:32:07 +0100
+Subject: [PATCH] arm64: dts: Update cache properties for broadcom
+
+The DeviceTree Specification v0.3 specifies that the cache node
+'compatible' and 'cache-level' properties are 'required'. Cf.
+s3.8 Multi-level and Shared Cache Nodes
+The 'cache-unified' property should be present if one of the
+properties for unified cache is present ('cache-size', ...).
+
+Update the Device Trees accordingly.

+Subject: [PATCH] net: broadcom: bcm4908_enet: use build_skb()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+RX code can be more efficient with the build_skb(). Allocating actual
+SKB around eth packet buffer - right before passing it up - results in
+a better cache usage.
+
+Without RPS (echo 0 > rps_cpus) BCM4908 NAT masq performance "jumps"
+between two speeds: ~900 Mbps and 940 Mbps (it's a 4 CPUs SoC). This
+change bumps the lower speed from 905 Mb/s to 918 Mb/s (tested using
+single stream iperf 2.0.5 traffic).
+
+There are more optimizations to consider. One obvious to try is GRO
+however as BCM4908 doesn't do hw csum is may actually lower performance.
+Sometimes. Some early testing:
+
+┌─────────────────────────────────┬─────────────────────┬────────────────────┐
+│                                 │ netif_receive_skb() │ napi_gro_receive() │
+├─────────────────────────────────┼─────────────────────┼────────────────────┤
+│ netdev_alloc_skb()              │            905 Mb/s │           892 Mb/s │
+│ napi_alloc_frag() + build_skb() │            918 Mb/s │           917 Mb/s │
+└─────────────────────────────────┴─────────────────────┴────────────────────┘
+
+Another ideas:
+1. napi_build_skb()
+2. skb_copy_from_linear_data() for small packets
+
+Those need proper testing first though. That can be done later.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Broadcom's CFE loader seems to miss setting SCR_EL3.HCE which results in
+generating an UNDEF and kernel panic on the first HVC.
+
+HVC gets issued by kernels 5.12+ while booting, by kexec and KVM. Until
+someone finds a workaround we have to avoid all above.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+GPHY needs to be enabled to succesfully probe & setup switch port
+connected to it. Otherwise hardcoding PHY OUI would be required.
