** Summary changed: - [SRU] Bump unmatched CPU clock rate to 1.5GHz + [SRU] Bump unmatched CPU clock rate to 1.2 GHz
** Description changed: [Impact] - Bump unmatched CPU clock rate to 1.5GHz + Bump SiFive Unmatched CPU clock rate from 1.0 GHz to 1.2 GHz as used by + upstream U-Boot. - Multiple users report that running unmatched at 1.5GHz is stable, and - gives one performance. - - Lets bump clock speed to 1.5GHz in u-boot and kernel. + This is the maximum frequency that according to SiFive is stable on all + boards. [Test Plan] * System with these patches boots, operates normally without - overheating. CPU clock speed is increased to 1.5GHz. + overheating. CPU clock speed is increased form 1.0 GHz to 1.2 GHz. [Where problems could occur] - * Overheating, instability, panics. + * Overheating, instability, panics. (Should not occur according to the + board vendor) [Other Info] - * wgrant & multiple forum users report this configuration to be stable + * wgrant & multiple SiFive forum users report even 1.5 GHz to be stable ** Tags added: riscv64 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1941622 Title: [SRU] Bump unmatched CPU clock rate to 1.2 GHz To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/u-boot/+bug/1941622/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
