** Description changed: [Impact] Starting in resolute, the patches from the PREEMPT_RT patchset will be applied to generic so they can be inherited by derivative kernels and flavors that need real-time. This set of patches will be filtered to only ones that apply where we support real-time, including amd64 and arm64. [Fix] For kernel 7.0, the upstream PREEMPT_RT patchset 7.0-rc1-rt1 has been - released. These patches will be applied to resolute:linux (but with + released. + + https://lore.kernel.org/linux-rt- + users/[email protected]/T/ + + These patches will be applied to resolute:linux (but with CONFIG_PREEMPT_RT disabled there) and inherited by other kernels. These patches include the following: UBUNTU: Real-time patchset 7.0-rc1-rt1 UBUNTU: SAUCE: sysfs: Add /sys/kernel/realtime entry UBUNTU: SAUCE: Revert "drm/i915: Depend on !PREEMPT_RT." UBUNTU: SAUCE: drm/i915: Consider RCU read section as atomic. UBUNTU: SAUCE: drm/i915/guc: Consider also RCU depth in busy loop. UBUNTU: SAUCE: drm/i915: Drop the irqs_disabled() check UBUNTU: SAUCE: drm/i915/gt: Use spin_lock_irq() instead of local_irq_disable() + spin_lock() UBUNTU: SAUCE: drm/i915: Disable tracing points on PREEMPT_RT UBUNTU: SAUCE: drm/i915: Don't disable interrupts on PREEMPT_RT during atomic updates UBUNTU: SAUCE: drm/i915: Use preempt_disable/enable_rt() where recommended UBUNTU: SAUCE: Reapply "serial: 8250: Revert "drop lockdep annotation from serial8250_clear_IER()"" UBUNTU: SAUCE: Reapply "serial: 8250: Switch to nbcon console" [Test Case] Compile and boot test [Where things could go wrong] These patches primarily apply to the 8250 serial driver and Intel i915 drm driver, so they may cause minor performance differences in these drivers even when PREEMPT_RT is disabled.
