Perhaps some of the module_param_named(,,int,) should be bool Also, are all of the various permissions appropriate? $ git grep module_param_named drivers/gpu/drm/radeon/ drivers/gpu/drm/radeon/radeon_drv.c:module_param_named(no_wb, radeon_no_wb, int, 0444); drivers/gpu/drm/radeon/radeon_drv.c:module_param_named(modeset, radeon_modeset, int, 0400); drivers/gpu/drm/radeon/radeon_drv.c:module_param_named(dynclks, radeon_dynclks, int, 0444); drivers/gpu/drm/radeon/radeon_drv.c:module_param_named(r4xx_atom, radeon_r4xx_atom, int, 0444); drivers/gpu/drm/radeon/radeon_drv.c:module_param_named(vramlimit, radeon_vram_limit, int, 0600); drivers/gpu/drm/radeon/radeon_drv.c:module_param_named(agpmode, radeon_agpmode, int, 0444); drivers/gpu/drm/radeon/radeon_drv.c:module_param_named(gartsize, radeon_gart_size, int, 0600); drivers/gpu/drm/radeon/radeon_drv.c:module_param_named(benchmark, radeon_benchmarking, int, 0444); drivers/gpu/drm/radeon/radeon_drv.c:module_param_named(test, radeon_testing, int, 0444); drivers/gpu/drm/radeon/radeon_drv.c:module_param_named(connector_table, radeon_connector_table, int, 0444); drivers/gpu/drm/radeon/radeon_drv.c:module_param_named(tv, radeon_tv, int, 0444); drivers/gpu/drm/radeon/radeon_drv.c:module_param_named(audio, radeon_audio, int, 0444); drivers/gpu/drm/radeon/radeon_drv.c:module_param_named(disp_priority, radeon_disp_priority, int, 0444); drivers/gpu/drm/radeon/radeon_drv.c:module_param_named(hw_i2c, radeon_hw_i2c, int, 0444); drivers/gpu/drm/radeon/radeon_drv.c:module_param_named(pcie_gen2, radeon_pcie_gen2, int, 0444); drivers/gpu/drm/radeon/radeon_drv.c:module_param_named(msi, radeon_msi, int, 0444); drivers/gpu/drm/radeon/radeon_drv.c:module_param_named(lockup_timeout, radeon_lockup_timeout, int, 0444);
