From: Maarten Lankhorst Date: Mon, 12 Jun 2017 10:21:15 +0000 (+0200) Subject: drm/i915: Pass atomic state to backlight enable/disable/set callbacks. X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7d025e0804f2cbeafeba2f5b8effa6361d7db8e4;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Pass atomic state to backlight enable/disable/set callbacks. Pass crtc_state to the enable callback, and connector_state to all callbacks. This will eliminate the need to guess for the correct pipe in these callbacks. The crtc state is required for pch_enable_backlight to obtain the correct cpu_transcoder. intel_dp_aux_backlight's setup function is called before hw readout, so crtc_state and connector_state->best_encoder are NULL in the enable() and set() callbacks. This fixes the following series of warns from intel_get_pipe_from_connector: [ 219.968428] ------------[ cut here ]------------ [ 219.968481] WARNING: CPU: 3 PID: 2457 at drivers/gpu/drm/i915/intel_display.c:13881 intel_get_pipe_from_connector+0x62/0x90 [i915] [ 219.968483] WARN_ON(!drm_modeset_is_locked(&dev->mode_config.connection_mutex)) [ 219.968485] Modules linked in: nls_iso8859_1 snd_hda_codec_hdmi snd_hda_codec_realtek snd_hda_codec_generic snd_hda_intel snd_hda_codec snd_hda_core snd_hwdep snd_pcm intel_rapl x86_pkg_temp_thermal coretemp kvm_intel snd_seq_midi snd_seq_midi_event kvm snd_rawmidi irqbypass crct10dif_pclmul crc32_pclmul ghash_clmulni_intel pcbc snd_seq snd_seq_device serio_raw snd_timer aesni_intel aes_x86_64 crypto_simd glue_helper cryptd lpc_ich snd mei_me shpchp soundcore mei rfkill_gpio mac_hid intel_pmc_ipc parport_pc ppdev lp parport ip_tables x_tables autofs4 hid_generic usbhid igb ahci i915 xhci_pci dca xhci_hcd ptp sdhci_pci sdhci libahci pps_core i2c_hid hid video [ 219.968573] CPU: 3 PID: 2457 Comm: kworker/u8:3 Tainted: G W 4.10.0-tip-201703010159+ #2 [ 219.968575] Hardware name: Intel Corp.
