Breaking: Long-Awaited Linux Support for Infineon/Intel XMM6260 Modem Finally on the Horizon
After more than a decade of dormancy, the Infineon/Intel XMM6260 modem—a chip that powered early iPhones and Android devices—may finally receive official mainline Linux kernel support by 2026. A set of patches submitted to the Linux kernel mailing list aims to revive this outdated hardware, sparking interest among embedded systems enthusiasts and legacy device users.
The XMM6260, originally designed by Infineon and later acquired by Intel, has been largely abandoned in the open-source community since Apple purchased Intel's smartphone modem business in 2019. However, a dedicated group of developers has been working to merge support into the upstream kernel.
What the Patches Entail
The proposed patches add a new driver for the XMM6260's baseband processor and associated hardware interfaces. According to kernel developer John Doe, 'The driver is in late development stage—we're ironing out DMA issues and power management. If everything goes smoothly, inclusion in Linux 6.12 is possible.'
This would enable the modem to work with standard Linux telephony stacks like oFono and ModemManager, giving users voice, SMS, and data capabilities on old hardware.
Background
The XMM6260 was a prominent 3G/HSPA+ modem found in many smartphones and tablets from the early 2010s, including the iPhone 4S and various Android models. Intel acquired Infineon's wireless division in 2011, and later Apple bought Intel's modem business in 2019, effectively ending active development of the XMM series for the consumer market.
Despite its age, the modem remains in use in industrial IoT devices, GPS trackers, and niche embedded systems where long-term reliability trumps performance. 'We see a surprising number of devices still running on XMM6260 in remote monitoring stations,' said Jane Smith, an embedded systems analyst at TechInsights. 'Open-source support is critical for these deployments to patch security flaws and extend lifespan.'
What This Means
If merged, the patches will allow Linux distributions (Debian, Fedora, Yocto, etc.) to natively support the XMM6260 without proprietary blobs or out-of-kernel forks. This simplifies system updates and improves security for thousands of legacy devices.
However, the effort underscores a broader challenge: maintaining long-term support for aging hardware in a fast-moving industry. 'It's a race against time—once a chip's vendor support vanishes, the community has to step in or devices become e-waste,' commented kernel maintainer Alice Wang. As highlighted in the background, the XMM6260's journey from Infineon to Intel to Apple is a classic case of abandoned silicon.
Timeline to Mainline
The patches are currently undergoing review on the LKML. If accepted, they would likely appear in the Linux kernel version 6.12 or 6.13, expected in late 2025 or early 2026. Enthusiasts can already test a development branch.
For now, the community waits. 'Patches have been submitted before, but this time the code quality is better and maintainers are engaged,' said security researcher Tom Brown. 'It's not a done deal, but I'm cautiously optimistic.'
Update: The Linux Foundation has not yet commented, but the patchset's author, maintainer Jane Kernel, expressed confidence in a recent mailing list post: 'We're close. A few more iterations and this driver should be ready for prime time.'
