Roman Li 739f35f027 drm/amd/display: Fix HPD after gpu reset ... commit 4de141b8b1 upstream. [Why] DC is not using amdgpu_irq_get/put to manage the HPD interrupt refcounts. So when amdgpu_irq_gpu_reset_resume_helper() reprograms all of the IRQs, HPD gets disabled. [How] Use amdgpu_irq_get/put() for HPD init/fini in DM in order to sync refcounts Cc: Mario Limonciello <mario.limonciello@amd.com> Cc: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Mario Limonciello <mario.limonciello@amd.com> Reviewed-by: Aurabindo Pillai <aurabindo.pillai@amd.com> Signed-off-by: Roman Li <Roman.Li@amd.com> Signed-off-by: Zaeem Mohamed <zaeem.mohamed@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> (cherry picked from commit f3dde2ff7f) Cc: stable@vger.kernel.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		History 2025-03-07 16:45:45 +01:00
