From: Sean Paul <seanpaul@xxxxxxxxxxxx> Instead of reaching into dev->primary for debugfs_root, use the minor passed into debugfs_init. This avoids creating a debug directory under /sys/kernel/debug/debug and instead uses /sys/kernel/debug/dri/<node>/ Since we're now putting everything under */dri/<node>, there's no need to create a duplicate "debug" directory. Just put everything in the root. Changes in v2: - Remove the unnecessary "debug" directory (Stephen) Link to v1: https://patchwork.freedesktop.org/patch/msgid/20190524173231.5040-1-sean@xxxxxxxxxx Cc: Rob Clark <robdclark@xxxxxxxxxxxx> Reported-by: Stephen Boyd <swboyd@xxxxxxxxxxxx> Reviewed-by: Abhinav Kumar <abhinavk@xxxxxxxxxxxxxx> Signed-off-by: Sean Paul <seanpaul@xxxxxxxxxxxx> --- drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c | 10 +++------- 1 file changed, 3 insertions(+), 7 deletions(-) diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c index 885bf88afa3ec..ad094704610f9 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c @@ -231,18 +231,14 @@ void *dpu_debugfs_create_regset32(const char *name, umode_t mode, regset, &dpu_fops_regset32); } -static int _dpu_debugfs_init(struct dpu_kms *dpu_kms) +static int _dpu_debugfs_init(struct dpu_kms *dpu_kms, struct drm_minor *minor) { void *p = dpu_hw_util_get_log_mask_ptr(); - struct dentry *entry; + struct dentry *entry = minor->debugfs_root; if (!p) return -EINVAL; - entry = debugfs_create_dir("debug", dpu_kms->dev->primary->debugfs_root); - if (IS_ERR_OR_NULL(entry)) - return -ENODEV; - /* allow root to be NULL */ debugfs_create_x32(DPU_DEBUGFS_HWMASKNAME, 0600, entry, p); @@ -581,7 +577,7 @@ static int _dpu_kms_drm_obj_init(struct dpu_kms *dpu_kms) #ifdef CONFIG_DEBUG_FS static int dpu_kms_debugfs_init(struct msm_kms *kms, struct drm_minor *minor) { - return _dpu_debugfs_init(to_dpu_kms(kms)); + return _dpu_debugfs_init(to_dpu_kms(kms), minor); } #endif -- Sean Paul, Software Engineer, Google / Chromium OS _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
