Message-Id: <20250514130727.67734-1-aishwarya.tcv@arm.com> Date: Wed, 14 May 2025 14:07:27 +0100 From: Aishwarya <aishwarya.tcv@....com> To: jeremy.linton@....com Cc: jmeurin@...gle.com, lenb@...nel.org, linux-acpi@...r.kernel.org, linux-kernel@...r.kernel.org, mheyne@...zon.de, rafael@...nel.org, stable@...r.kernel.org, sudeep.holla@....com, yangyicong@...ilicon.com, ryan.roberts@....com Subject: Re: [PATCH] ACPI: PPTT: Fix processor subtable walk Hi Jeremy, Thanks for providing this fix. We've tested applying the patch on top of v6.15-rc6 and would like to confirm that commit 7ab4f0e37a0f4207e742a8de69be03984db6ebf0 was indeed the root cause of a severe performance regression observed on Graviton3 bare-metal systems during the 6.15 development cycle. After applying the patch, all regressions were fully resolved. The degradation began in v6.15-rc2 and persisted through rc6. Through bisection, we identified the above commit as introducing incorrect handling in ACPI PPTT parsing. This likely caused malformed CPU topology and broken scheduling domains. As further evidence, we observed the following warning in the kernel logs during affected runs. This was with: Linux version 6.15.0-rc6 [ 0.511191] ------------[ cut here ]------------ [ 0.511193] WARNING: CPU: 0 PID: 1 at kernel/sched/topology.c:2411 build_sched_domains+0x674/0x1204 [ 0.511201] Modules linked in: [ 0.511205] CPU: 0 UID: 0 PID: 1 Comm: swapper/0 Tainted: G S 6.15.0-rc6 #1 PREEMPT [ 0.511209] Tainted: [S]=CPU_OUT_OF_SPEC [ 0.511211] pstate: 01400009 (nzcv daif +PAN -UAO -TCO +DIT -SSBS BTYPE=--) [ 0.511214] pc : build_sched_domains+0x674/0x1204 [ 0.511217] lr : build_sched_domains+0x354/0x1204 [ 0.511220] sp : ffff80008021bce0 [ 0.511222] x29: ffff80008021bd60 x28: ffff00010253e300 x27: ffff000100b74440 [ 0.511226] x26: ffffdd63645167f8 x25: ffffdd636373aee8 x24: 0000000000001297 [ 0.511229] x23: ffffdd6364aa4518 x22: 000000000000003f x21: 0000000000000000 [ 0.511233] x20: ffffdd63644fb030 x19: ffff0001014e9270 x18: ffffffffff435f00 [ 0.511236] x17: 4d52415120646574 x16: 6365746968637261 x15: 0000000000000001 [ 0.511239] x14: 0000000000000000 x13: 0000000000000318 x12: 0000000000002000 [ 0.511243] x11: ffff00815ff0e154 x10: ffffdd6364aa4518 x9 : ffffdd6364aa4510 [ 0.511246] x8 : ffffdd6364aa8780 x7 : 0000000000000002 x6 : 7fffffffffffffff [ 0.511249] x5 : ffffffffffffffff x4 : 0000000000000002 x3 : 0000000000000001 [ 0.511252] x2 : 0000000000000040 x1 : ffffdd6364aa8788 x0 : 0000000000000001 [ 0.511256] Call trace: [ 0.511258] build_sched_domains+0x674/0x1204 (P) [ 0.511262] sched_init_domains+0xc8/0x104 [ 0.511267] sched_init_smp+0x40/0xc0 [ 0.511270] kernel_init_freeable+0x100/0x28c [ 0.511273] kernel_init+0x20/0x1d8 [ 0.511277] ret_from_fork+0x10/0x20 [ 0.511281] ---[ end trace 0000000000000000 ]--- Based on this, we believe the truncation of the PPTT was confusing the scheduler about the system's CPU topology. This likely explains the observed regressions. Example impact (`pts/pgbench` with 100 clients / 1000 scale): - TPS dropped by up to -98.8% - Latency increased by over +8200% Other workloads affected: - mmtests/sysbench-thread showed ~+600% increase in latency - mmtests/stressng-* (get, wait, vm-splice) regressed by -90%+ - pts/memtier and nginx throughput dropped by ~98% We’ve shared the full benchmark results in the thread below to support these findings. +------------------------------------+----------------------------------------------------------+-----------------+--------------+----------------------------+ | Benchmark |
