Linux 6.4 release – Main changes, Arm, RISC-V and MIPS architectures

Linux 6.4 release

Linux 6.4 has just been released by Linus Torvalds on the Linux Kernel Mailing List (LKML): Hmm. Final week of 6.4 is done, and we’ve mainly got some netfilter fixes, some mm reverts, and a few tracing updates. There’s random small changes elsewhere: the usual architecture noise, a number of selftest updates, some filesystem fixes (btrfs, ksmb), etc. Most of the stuff in my mailbox the last week has been about upcoming things for 6.5, and I already have 15 pull requests pending. I appreciate all you proactive people. But that’s for tomorrow. Today we’re all busy build-testing the newest kernel release, and checking that it’s all good. Right? Released around two months ago, Linux 6.3 brought us AMD’s “automatic IBRS” Spectre defense mechanism, additional progress on the Rust front with User-mode Linux support (on x86-64 systems only), the NFS filesystem (both the client and server sides) gained support for […]

Broadcom unveils 2nd generation WiFi 7 chipsets: BCM6765, BCM47722, BCM4390

Broadcom WiFi 7 Gen2: BCM6765, BCM47722, BCM4390

Broadcom has announced its second generation WiFi 7 chipsets: the BCM6765 residential WiFi 7 access point chip, the BCM47722 enterprise WiFi 7 access point chip with dual IoT radios that support simultaneous operation for Bluetooth Low Energy (BLE), Zigbee, Thread, and Matter protocols, and the BCM4390 low-power Wi-Fi 7, Bluetooth, and 802.15.4 combo chip designed for use in mobile devices. This follows the introduction of Broadcom’s first WiFi 7 chipsets in April 2022 with residential and enterprise WiFi 7 access point chips, and a WiFi 7 client chip, but the second generation access point chipsets support 320 MHz 2-stream Wi-Fi operation and add extra features, and the BCM4390 optimized costs bringing WiFi 7 to lower-prices phones and devices. BCM6765 residential Wi-Fi access point chip highlights: CPU – Quad-core ARMv8 CPU with 10Gbps Ethernet PHY WiFi 7 Dual 2×2 tri-band (2.4, 5, and 6 GHz) capable radios that support simultaneous operation […]

Realtek WiFi 7 and WiFi 6 roadmap for routers and clients

Realtek Testbed WiFi 7

We’ve just written about Realtek 5 Gbps Ethernet chips, but the company also has some roadmaps for WiFi 6 and WiFi 7 router chips, and a WiFi 7 client module demonstrated at COMPUTEX 2023. The company’s roadmap include five WiFi 7 router solutions: WiFi 7 BE6500 router with a Realtek 8198DS dual Arm core processor @ 1.2 GHz with an RTL8952AR 2×2 MIMO 5 GHz and 6 GHz chip, RTL8902A 2×2 2.4 GHz chip, and an RTL8221B 2.5GbE PHY WiFi 7 BE9400 router with a Realtek 8198DS dual Arm core processor @ 1.2 GHz with an RTL8952AR 2×2 MIMO 5 GHz chip, RTL8902A 2×2 2.4 GHz chip, an RTL8934AR 4×4 MIMO 6 GHz chip, and an RTL8221B 2.5GbE PHY WiFi 7 BE3400 router with a Realtek 8198DS dual Arm core processor @ 1.2 GHz with an RTL8952AR 2×2 MIMO 5 GHz chip, and an RTL8221B 2.5GbE PHY WiFi 7 BE6400 […]

Linux 6.3 release – Notable changes, Arm, RISC-V and MIPS architectures

Linux 6.3 release

Linux Torvalds has just announced the release of Linux 6.3 on the Linux Kernel Mailing List (LKML): It’s been a calm release this time around, and the last week was really no different. So here we are, right on schedule, with the 6.3 release out and ready for your enjoyment. That doesn’t mean that something nasty couldn’t have been lurking all these weeks, of course, but let’s just take things at face value and hope it all means that everything is fine, and it really was a nice controlled release cycle. It happens. This also obviously means the merge window for 6.4 will open tomorrow. I already have two dozen pull requests waiting for me to start doing my pulls, and I appreciate it. I expect I’ll have even more when I wake up tomorrow. But in the meantime, let’s enjoy (and test) the 6.3 release. As always, the shortlog […]

$700 Netgear RS700 WiFi 7 router supports up to 19Gbps (combined) speed

Netgear RS700 WiFi 7 router

Netgear “Nighthawk” RS700 is the first WiFi 7 (802.11be) router from the company, with the tri-band router being rated “BE19000” meaning it can deliver a combined ~19Gbps link rate using all three bands. The router is based on the Broadcom BCM67263 Arm processor and with that kind of wireless bandwidth it comes with two 10GbE ports one WAN port to connect to the internet, and one LAN port to connect to the local networks plus four extra Gigabit Ethernet ports, and a USB 3.0 port for network storage.

Linux 6.2 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 6.2 release

Linux 6.2 has just been released with Linus Torvalds making the announcement on LKML as usual: So here we are, right on (the extended) schedule, with 6.2 out. Nothing unexpected happened last week, with just a random selection of small fixes spread all over, with nothing really standing out. The shortlog is tiny and appended below, you can scroll through it if you’re bored. Wed have a couple of small things that Thorsten was tracking on the regression side, but I wasn’t going to apply any last-minute patches that weren’t actively pushed by maintainers, so they will have to show up for stable. Nothing seemed even remotely worth trying to delay things for. And this obviously means that the 6.3 merge window will open tomorrow, and I already have 30+ pull requests queued up, which I really appreciate. I like how people have started to take the whole “ready for […]
