Subject: Re: [PATCH v5 0/4] add support for self monitoring
Date: Thu, 16 Feb 2023 20:56:55 +0000	[thread overview]
Message-ID: <Y+6Yl7IIjWng4cfw@C02GF04TMD6V> (raw)
In-Reply-To: <20230110234642.1188550-1-tduszynski@marvell.com>

PMU is kind of MSR. Precisely , that's MSR per core. 
All MSR reading will lead to IPI(Please reference the kernel
implementation of MSR driver). The IPI will disturb the DPDK application
because the userspace/kernel context switch, which has impact to the
tail latency.
