Fed-up Torvalds suggests disabling AMD’s 'stupid' performance-killing fTPM RNG

> Ongoing issues with Linux and AMD's fTPM – the chip designer's firmware-based TPM – appear to be wearing on kernel overseer Linus Torvalds' nerves, who has suggested switching off the module's random number generator altogether.

> "Let's just disable the stupid fTPM hwrnd thing," Torvalds said on the open source kernel's development mailing list. "Maybe use it for the boot-time 'gather entropy from different sources,' but clearly it should not be used at runtime."

> TPMs, whether they're firmware or hardware based, are used to securely create and store cryptographic keys, certificates, and passwords. The modules also, among things, generate random numbers for software to use.

Linux Creator Expresses “Frustration” Towards AMD’s fTPM Bugs, Calls To Disable Feature [Ed: Microsoft's TPM garbage sabotaging Linux, just like UEFI 'secure boot'; it's being pushed by Microsoft incel and crackhead Matthew Garrett. Garrett openly badmouths the quality of Linux code. It's a Microsoft mole/mule, not a Linux developer. A pathological liar. Torvalds is under a malicious attack from Microsoft, but he'd never openly admit it.]

Qualcomm Iris video decoder & encoder gets Linux V4L2 driver

↺ Qualcomm Iris video decoder & encoder gets Linux V4L2 driver

> Qualcomm engineer Vikash Garodia has just pushed a commit to add “Qualcomm Iris V4L2 encoder/decoder driver” to mainline Linux enabling support for H.264, H.265, and VP9 decoding, H.264 and H.265 encoding, as well as M2M and STREAMING capabilities. The Adreno GPUs found in Qualcomm SoC have been supported by the open-source Freedreno driver for several years, but this was not the case with the IP block taking care of hardware video encoding and decoding. The latest patchset addresses this issue for “Qualcomm’s new video acceleration hardware architecture”, meaning it might not work for older Qualcomm processors.
