Linux 5.19 Looks Like It Will Be The Base Requirement For Intel Arc Graphics / Alchemist

Phoronix - Tue, 04/26/2022 - 19:13
While Intel launched the Arc A-Series Mobile Graphics at the end of Q1, so far at least in major US markets no laptops with these graphics are currently available. As such it's hard to assess the current Linux driver support level and with no clear communication from Intel on the matter. Intel has been working on their upstream DG2/Alchemist support for a while but it looks like with the Linux 5.19 kernel this summer is what will likely be their base version requirement for the DG2/Alchemist-based Intel GPUs...

Concerns Raised Over The "New" NTFS Linux Driver That Merged Last Year

Phoronix - Tue, 04/26/2022 - 18:25
Back in 2020 file-system driver provider Paragon Software announced they wanted to upstream their NTFS driver into the Linux kernel. This driver was previously a proprietary, commercial offering from the company but given the state of NTFS these days they wanted to upstream this driver with full read/write support and other features not found within the existing NTFS driver. Finally last year after going through many rounds of review, the new driver was merged into Linux 5.15. Sadly, less than one year later, concerns have been raised that the driver is already effectively orphaned and not being maintained...

/dev/random + /dev/urandom Unification May Be Revisited In The Future, Blocker Addressed

Phoronix - Tue, 04/26/2022 - 17:30
Originally attempted with Linux 5.18 were patches so /dev/urandom and /dev/random would behave exactly the same. That was dropped though due to not enough randomness at boot for some platforms like Arm 32-bit, Motorola m68k, Microblaze, Xtensa, and others. But then the change went in to opportunistically initialize /dev/random as a best-effort approach where it at least works nicely on x86/x86_64. The good news is that original unification effort may be re-visited in the future now that the original blocker issue has been addressed...
