I wondered the same thing, but a quick search showed that "LG UltraPC 17U70P" is " LG Ultra PC 17” Lightweight & High Performance Laptop Intel® 11th Gen Core® i7, NVIDIA® GeForce® GTX™ 1650Ti Graphics, Windows 11 Home, 16GB RAM, 512GB SSD, Silver" So I don't think so. > > > Cc: ofenfisch@googlemail.com > > Cc: wse@tuxedocomputers.com > > Cc: adam.niederer@gmail.com > > Cc: adrian@freund.io > > Cc: jirislaby@kernel.org > > Tested-by: Renjith.Pananchikkal@amd.com > > Tested-by: anson.tsao@amd.com > > Tested-by: Richard.Gong@amd.com > > Tested-by: Chuanhong Guo <gch981213@gmail.com> > > Reported-by: evilsnoo@proton.me > > Closes: https://bugzilla.kernel.org/show_bug.cgi?id=217394 > > Reported-by: ruinairas1992@gmail.com > > Closes: https://bugzilla.kernel.org/show_bug.cgi?id=217406 > > Fixes: 9946e39fe8d0 ("ACPI: resource: skip IRQ override on AMD Zen > platforms") > > Signed-off-by: Mario Limonciello <mario.limonciello@amd.com> > > --- > > v1->v2: > > * Rebase on 71a485624c4c ("ACPI: resource: Add IRQ override quirk for LG > UltraPC 17U70P") > > * Pick up tag > > --- > > drivers/acpi/resource.c | 154 +++++++++++++++++----------------------- > > 1 file changed, 65 insertions(+), 89 deletions(-) > > > > diff --git a/drivers/acpi/resource.c b/drivers/acpi/resource.c > > index 0800a9d77558..c6ac87e01e1c 100644 > > --- a/drivers/acpi/resource.c > > +++ b/drivers/acpi/resource.c > > @@ -470,52 +470,6 @@ static const struct dmi_system_id asus_laptop[] = { > > { } > > };

Hey, I have tested 6.4-rc3 and this breaks the integrated trackpad on my MAINGEAR Vector Pro 2 15" 6900H model (MG-VCP2-15A3070T), but the keyboard still works (the trackpad worked and keyboard did not before I submitted my ACPI override). I'll send over an acpidump directly as well.

But for reference: here it was discussed too: https://bugzilla.kernel.org/show_bug.cgi?id=216698 Note that TF did eventually provide a fixed BIOS, but most likely not all vendors ship that BIOS and/or all users are aware that this fix exists.

commit 9946e39fe8d0 ("ACPI: resource: skip IRQ override on AMD Zen platforms") attempted to overhaul the override logic so it didn't apply on X86 AMD Zen systems. This was intentional so that systems would prefer DSDT values instead of default MADT value for IRQ 1 on Ryzen 6000 systems which use ActiveLow for IRQ1. This turned out to be a bad assumption because several vendors seem to add Interrupt Source Override but don't fix the DSDT. A pile of quirks was collecting that proved this wasn't sustaintable. Adjust the logic so that only IRQ1 is overridden in Ryzen 6000 case. This effectively reverts the following commits: commit 17bb7046e7ce ("ACPI: resource: Do IRQ override on all TongFang GMxRGxx") commit f3cb9b740869 ("ACPI: resource: do IRQ override on Lenovo 14ALC7") commit bfcdf58380b1 ("ACPI: resource: do IRQ override on LENOVO IdeaPad") commit 7592b79ba4a9 ("ACPI: resource: do IRQ override on XMG Core 15") Cc: ofenfisch@googlemail.com Cc: wse@tuxedocomputers.com Cc: adam.niederer@gmail.com Cc: adrian@freund.io Cc: jirislaby@kernel.org Tested-by: Renjith.Pananchikkal@amd.com Tested-by: anson.tsao@amd.com Tested-by: Richard.Gong@amd.com Tested-by: Chuanhong Guo <gch981213@gmail.com> Reported-by: evilsnoo@proton.me Closes: https://bugzilla.kernel.org/show_bug.cgi?id=217394 Reported-by: ruinairas1992@gmail.com Closes: https://bugzilla.kernel.org/show_bug.cgi?id=217406 Fixes: 9946e39fe8d0 ("ACPI: resource: skip IRQ override on AMD Zen platforms") Signed-off-by: Mario Limonciello <mario.limonciello@amd.com> --- v1->v2: * Rebase on 71a485624c4c ("ACPI: resource: Add IRQ override quirk for LG UltraPC 17U70P") * Pick up tag --- drivers/acpi/resource.c | 154 +++++++++++++++++----------------------- 1 file changed, 65 insertions(+), 89 deletions(-) base-commit: c554eee18c9a440bd2dd5a363b0f79325717f0bf
