From eafc4894d0a6a773970b40dd092dbc0771ed39b5 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 14 Oct 2016 14:44:28 +0100 Subject: [PATCH] drm/i915: Add a sunset clause to GPU hang logging If the kernel is old, more than a few releases old, chances are that the user is using an old kernel for a good reason, despite there being GPU hangs. After 180days since driver release stop suggesting that they should send those reports upstream. [Since Daniel acked this I expect he will pick up the dim patch to automatically update the DRIVER_TIMESTAMP everytime we tag a new release.] Signed-off-by: Chris Wilson Cc: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/20161014134428.29582-1-chris@chris-wilson.co.uk Acked-by: Daniel Vetter Reviewed-by: Joonas Lahtinen --- drivers/gpu/drm/i915/i915_drv.h | 1 + drivers/gpu/drm/i915/i915_gpu_error.c | 5 ++++- 2 files changed, 5 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h index b339c916f7a9..c278c5af6174 100644 --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -71,6 +71,7 @@ #define DRIVER_NAME "i915" #define DRIVER_DESC "Intel Graphics" #define DRIVER_DATE "20161010" +#define DRIVER_TIMESTAMP 1476452087 #undef WARN_ON /* Many gcc seem to no see through this and fall over :( */ diff --git a/drivers/gpu/drm/i915/i915_gpu_error.c b/drivers/gpu/drm/i915/i915_gpu_error.c index a8ce358850d1..242b9a927899 100644 --- a/drivers/gpu/drm/i915/i915_gpu_error.c +++ b/drivers/gpu/drm/i915/i915_gpu_error.c @@ -1541,6 +1541,8 @@ static int capture(void *data) return 0; } +#define DAY_AS_SECONDS(x) (24 * 60 * 60 * (x)) + /** * i915_capture_error_state - capture an error record for later analysis * @dev: drm device @@ -1593,7 +1595,8 @@ void i915_capture_error_state(struct drm_i915_private *dev_priv, return; } - if (!warned) { + if (!warned && + ktime_get_real_seconds() - DRIVER_TIMESTAMP < DAY_AS_SECONDS(180)) { DRM_INFO("GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.\n"); DRM_INFO("Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel\n"); DRM_INFO("drm/i915 developers can then reassign to the right component if it's not a kernel issue.\n"); -- 2.45.2
