If we are moving display parameters to intel_display_params.[ch] they are not dumped into GPU error dump. This patch is adding moved display parameters back to GPU error dump. Display parameters are also included in i915_capabilities v2: Add parameters to i915_capabilities as well Signed-off-by: Jouni Högander Reviewed-by: Luca Coelho --- .../drm/i915/display/intel_display_params.c | 57 +++++++++++++++++++ .../drm/i915/display/intel_display_params.h | 3 + drivers/gpu/drm/i915/i915_debugfs.c | 3 + drivers/gpu/drm/i915/i915_gpu_error.c | 3 + drivers/gpu/drm/i915/i915_gpu_error.h | 2 + 5 files changed, 68 insertions(+) diff --git a/drivers/gpu/drm/i915/display/intel_display_params.c b/drivers/gpu/drm/i915/display/intel_display_params.c index 91953ae27144..11ee73a98b5b 100644 --- a/drivers/gpu/drm/i915/display/intel_display_params.c +++ b/drivers/gpu/drm/i915/display/intel_display_params.c @@ -27,6 +27,63 @@ static struct intel_display_params intel_display_modparams __read_mostly = { * debugfs mode to 0. */ +__maybe_unused +static void _param_print_bool(struct drm_printer *p, const char *driver_name, + const char *name, bool val) +{ + drm_printf(p, "%s.%s=%s\n", driver_name, name, str_yes_no(val)); +} + +__maybe_unused +static void _param_print_int(struct drm_printer *p, const char *driver_name, + const char *name, int val) +{ + drm_printf(p, "%s.%s=%d\n", driver_name, name, val); +} + +__maybe_unused +static void _param_print_uint(struct drm_printer *p, const char *driver_name, + const char *name, unsigned int val) +{ + drm_printf(p, "%s.%s=%u\n", driver_name, name, val); +} + +__maybe_unused +static void _param_print_ulong(struct drm_printer *p, const char *driver_name, + const char *name, unsigned long val) +{ + drm_printf(p, "%s.%s=%lu\n", driver_name, name, val); +} + +__maybe_unused +static void _param_print_charp(struct drm_printer *p, const char *driver_name, + const char *name, const char *val) +{ + drm_printf(p, "%s.%s=%s\n", driver_name, name, val); +} + +#define _param_print(p, driver_name, name, val) \ + _Generic(val, \ + bool : _param_print_bool, \ + int : _param_print_int, \ + unsigned int : _param_print_uint, \ + unsigned long : _param_print_ulong, \ + char * : _param_print_charp)(p, driver_name, name, val) + +/** + * intel_display_params_dump - dump intel display modparams + * @i915: i915 device + * @p: the &drm_printer + * + * Pretty printer for i915 modparams. + */ +void intel_display_params_dump(struct drm_i915_private *i915, struct drm_printer *p) +{ +#define PRINT(T, x, ...) _param_print(p, i915->drm.driver->name, #x, i915->display.params.x); + INTEL_DISPLAY_PARAMS_FOR_EACH(PRINT); +#undef PRINT +} + __maybe_unused static void _param_dup_charp(char **valp) { *valp = kstrdup(*valp ?
