From b905580202f0da5ca0a6268b176b4591e347fd8d Mon Sep 17 00:00:00 2001 From: Takoroka <137927095+Takoroka@users.noreply.github.com> Date: Thu, 29 Oct 2026 05:46:59 -0400 Subject: video_core: compact the macro memo arena; download profiling counters Calls stored again with another shape leave their old record in the memo's arena; title 1 filled its 16 MiB every ~2 s and clearing it made the next ~20,000 calls interpret again. The live records are now copied to a new arena (a clear only when they alone fill three quarters of it). The memo statistics count hits on the last call's slot and compactions. With EDEN_NX2_GPU_PROFILE the GPU thread also reports how much downloaded buffer data lands on pages the native MME has DMA-read. --- src/video_core/buffer_cache/buffer_cache.h | 13 +++++++++++++ 1 file changed, 13 insertions(+) (limited to 'src/video_core/buffer_cache') diff --git a/src/video_core/buffer_cache/buffer_cache.h b/src/video_core/buffer_cache/buffer_cache.h index e2de0eede1..b909971e42 100644 --- a/src/video_core/buffer_cache/buffer_cache.h +++ b/src/video_core/buffer_cache/buffer_cache.h @@ -679,6 +679,19 @@ void BufferCache
