From e144abe6a55d7c837cc9deda0c2757549bd4ce14 Mon Sep 17 00:00:00 2001 From: Janne Grunau Date: Sun, 3 Nov 2024 11:17:56 +0100 Subject: [PATCH] pmgr: Fix false positive u8 pmgr ID detection on modern SoCs The id1 field used on oder SoCs is not constant 0 for all devices on t8122. Instead just compare the id1 fields of the two first devices. Fixes "pmgr: Failed to find parent #36 for IOA0\n" errors in pmgr_init(). Fixes: fb59dc03ca9a ("pmgr: Fix struct for older SoCs") Signed-off-by: Janne Grunau --- src/pmgr.c | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/src/pmgr.c b/src/pmgr.c index 5808fcd8c..d78bc8e6b 100644 --- a/src/pmgr.c +++ b/src/pmgr.c @@ -374,13 +374,15 @@ int pmgr_init(void) printf("pmgr: Cleaning up device states...\n"); + // detect whether u8 or u16 PMGR IDs are used by comparing the IDs of the + // first 2 devices + if (pmgr_devices_len >= 2) + pmgr_u8id = pmgr_devices[0].id1 != pmgr_devices[1].id1; + for (u8 die = 0; die < pmgr_dies; ++die) { for (size_t i = 0; i < pmgr_devices_len; ++i) { const struct pmgr_device *device = &pmgr_devices[i]; - if (device->id1) - pmgr_u8id = true; - if ((device->flags & PMGR_FLAG_VIRTUAL)) continue;
