From 7d88261d01100e46a5160319b94b1e79b5eb1117 Mon Sep 17 00:00:00 2001 From: Arthur Hanson Rasmusson Date: Thu, 5 Nov 2026 10:34:40 -0500 Subject: vgsp-gr: capture the full 4K-word GL draw window, emit SET_SHADER_EXCEPTIONS as immd13, and base the SPH region on the bound program's shadow page - SVC_GR_PUSH_WORDS / GSP_PHYS_GR_RAW_WORDS raised 2048 -> 4096: the beef full-frame push is 12288 B / 3072 words, so the 2048-word capture tail failed the 3D mark (raw_ok=0 fit_ok=0) and the launch fell back to a 239-word stub, losing the real 2115-word draw. Now '3D stream chunked window=1429 words -> 4 chunk(s)'. - SET_SHADER_EXCEPTIONS (0x1528) is emitted as the client's immd13 (0x8000054a) and skipped when the window already carries it; the remaining 0x1528 in the log is the client's own benign write. - sema_gl_sph_region_bind (default 1): the SPH region base is the first bound program's relocated shadow page, not the forced 0x1500000 pool base; r1484 latched the fetched SPHs (0,019a0f00,019a0200,0,0,019a0000) with ds=86040646 (region mismatch), r1485 uses base 0x19b0000 bind 0x19b0900 and the DS accepts (ds=80000000). - r1484/r1485: the screen now shows gear-class pixels (xwd bbox spanning the 800x600 window, multicolor); GUEST-WIT shows RT0 page 0 written. The remaining wall is the MME draw macro 0xf1 / pc 513 poison on the first calls+window launch after the arming hold is released. --- kernel/gsp_sema_service.c | 16 ++++++++++++++-- 1 file changed, 14 insertions(+), 2 deletions(-) (limited to 'kernel/gsp_sema_service.c') diff --git a/kernel/gsp_sema_service.c b/kernel/gsp_sema_service.c index 18d5e78..327a932 100644 --- a/kernel/gsp_sema_service.c +++ b/kernel/gsp_sema_service.c @@ -7420,8 +7420,20 @@ static struct svc_fwd_cand svc_fwd_cand; * (CONT-44: zero src=stream captures on the client channel).
