959314c438ca broke behavior at least on GA107GLM RTX A1000 on Thinkpad P16, which has GPU in dock. unplugging dock freezes GUI on KDE5 Plasma, plugging dock freezes GUI on GNOME.
As a workaround avoid setting value on NOUVEAU_GETPARAM_HAS_VMA_TILEMODE for nv177. Signed-off-by: Petr Vorel <[email protected]> --- Hi all, obviously this is not a solution (that's why RFC and I don't set Fixes: 959314c438ca), but it documents that hardware is unusable with 959314c438ca. FYI we are going to not set getparam->value for NOUVEAU_GETPARAM_HAS_VMA_TILEMODE for any GPU on openSUSE Tumbleweed. https://bugzilla.suse.com/show_bug.cgi?id=1198108 Kind regards, Petr drivers/gpu/drm/nouveau/nouveau_abi16.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/nouveau/nouveau_abi16.c b/drivers/gpu/drm/nouveau/nouveau_abi16.c index a3ba07fc48a08..fefaf7287723c 100644 --- a/drivers/gpu/drm/nouveau/nouveau_abi16.c +++ b/drivers/gpu/drm/nouveau/nouveau_abi16.c @@ -323,7 +323,12 @@ nouveau_abi16_ioctl_getparam(ABI16_IOCTL_ARGS) break; } case NOUVEAU_GETPARAM_HAS_VMA_TILEMODE: - getparam->value = 1; + if (drm->client.device.info.chipset != 0x177) { + getparam->value = 1; + } else { + NV_PRINTK(dbg, cli, "Ignoring NOUVEAU_GETPARAM_HAS_VMA_TILEMODE for 0x%x\n", + drm->client.device.info.chipset); + } break; default: NV_PRINTK(dbg, cli, "unknown parameter %lld\n", getparam->param); -- 2.51.0
