Subject: [PATCH v2] x86/resctrl: Fix WARN in get_domain_from_cpu()
Date: Wed, 21 Feb 2024 11:31:18 -0800 [thread overview]
Message-ID: <ZdZPht8hY4J9uIOz@agluck-desk3> (raw)
In-Reply-To: <ZdVFDIJmctsNaGd2@agluck-desk3>
reset_all_ctrls() and resctrl_arch_update_domains() use on_each_cpu_mask()
to call rdt_ctrl_update() on potentially one CPU from each domain.
But this means rdt_ctrl_update() needs to figure out which domain to
apply changes to. Doing so requires a search of all domains in a resource,
which can only be done safely if cpus_lock is held. Both callers do hold
this lock, but there isn't a way for a function called on another CPU
via IPI to verify this.
Fix by adding the target domain to the msr_param structure and passing an
array with CDP_NUM_TYPES entries. Then calling for each domain separately
using smp_call_function_single()
Change the low level cat_wrmsr(), mba_wrmsr_intel(), and mba_wrmsr_amd()
functions to just take a msr_param structure since it contains the
rdt_resource and rdt_domain information.
Signed-off-by: Tony Luck <tony.luck@intel.com>
---
Changes since v1:
* Avoid double IPI to the same core when CDP is enabled.
* Don't pass the resource and domain to functions that can
get these from the msr_param structure.
* Clean up some fir tree issues in functions that I changed.
