2019-08-21drm/amd/display: Calculate bpc based on max_requested_bpcNicholas Kazlauskas
[Why] The only place where state->max_bpc is updated on the connector is at the start of atomic check during drm_atomic_connector_check. It isn't updated when adding the connectors to the atomic state after the fact. It also doesn't necessarily reflect the right value when called in amdgpu during mode validation outside of atomic check. This can cause the wrong bpc to be used even if the max_requested_bpc is the correct value. [How] Don't rely on state->max_bpc reflecting the real bpc value and just do the min(...) based on display info bpc and max_requested_bpc.

2019-08-21drm/amdgpu/gfx9: update pg_flags after determining if gfx off is possibleAlex Deucher
We need to set certain power gating flags after we determine if the firmware version is sufficient to support gfxoff. Previously we set the pg flags in early init, but we later we might have disabled gfxoff if the firmware versions didn't support it. Move adding the additional pg flags after we determine whether or not to support gfxoff.

2019-08-21drm: kirin: Move ade drm init to kirin drm drvXu YiPing
As part of refactoring the kirin driver to better support different hardware revisions, this patch renames ade_data to kirin_drm_private, and moves crtc_init and plane_init to kirin drm drv too. Now that they are generic the functions can be shared between the kirin620 and (to be added later) kirin960 specific support code.

As part of refactoring the kirin driver to better support different hardware revisions, this patch removes the out_format field in the struct ade_crtc, which was only ever set to LDI_OUT_RGB_888. Thus this patch removes the field and instead directly uses LDI_OUT_RGB_888.

In a few functions, we pass in a struct ade_crtc, which we only use to get to the underlying struct ade_hw_ctx. Thus this patch refactors the functions to just take the struct ade_hw_ctx directly.

2019-08-21drm: kirin: Fix for hikey620 display offset problemDa Lv
The original HiKey (620) board has had a long running issue where when using a 1080p montior, the display would occasionally blink and come come back with a horizontal offset (usually also shifting the colors, depending on the value of the offset%4). After lots of analysis by HiSi developers, they found the issue was due to when running at 1080p, it was possible to hit the device memory bandwidth limits, which could cause the DSI signal to get out of sync. Unfortunately the DSI logic doesn't have the ability to automatically recover from this situation, but we can get a an LDI underflow interrupt when it happens. To then correct the issue, when we get an LDI underflow irq, we we can simply suspend and resume the display, which resets the hardware. Thus, this patch enables the ldi underflow interrupt, and initializes a workqueue that is used to suspend/resume the display to recover. Then when the irq occurs we clear it and schedule the workqueue to reset display engine.

2019-08-21drm/i915: Replace PIN_NONFAULT with calls to PIN_NOEVICTChris Wilson
When under severe stress for GTT mappable space, the LRU eviction model falls off a cliff. We spend all our time scanning the much larger non-mappable area searching for something within the mappable zone we can evict. Turn this on its head by only using the full vma for the object if it is already pinned in the mappable zone or there is sufficient *free* space to accommodate it (prioritizing speedy reuse). If there is not, immediately fall back to using small chunks (tilerow for GTT mmap, single pages for pwrite/relocation) and using random eviction before doing a full search.

2019-08-20drm/i915/tgl: disable DDICLucas De Marchi
The current SKUs added for Tiger Lake don't have DDIC hooked up, even though it is supported by the SoC. The current state for these SKUs is problematic since while enabling the combo phy, PORT_COMP_DW* return 0xFFFFFFFF, which is invalid per register definition. During initialization we check what phys are not yet enabled by reading PHY_MISC_C and try to enable it by toggling the "DE to IO Comp Pwr Down" bit. But after that any read to the PORT_COMP_DW* returns invalid results. This removes the following warning [56997.634353] Missing case (val == 4294967295) [56997.639241] WARNING: CPU: 5 PID: 768 at drivers/gpu/drm/i915/display/intel_combo_phy.c:54 cnl_get_procmon_ref_values+0xc9/0xf0 [i915] [56997.639808] Modules linked in: i915(+) prime_numbers x86_pkg_temp_thermal coretemp kvm_intel kvm irqbypass crct10dif_pclmul crc32_pclmul ghash_clmulni_intel e1000e [last unloaded: prime_numbers] [56997.639808] CPU: 5 PID: 768 Comm: insmod Tainted: G U W 5.2.0-demarchi+ #65 [56997.639808] Hardware name: Intel Corporation Tiger Lake Client Platform/TigerLake U DDR4 SODIMM RVP, BIOS TGLSFWI1.R00.2252.A03.1906270154 06/27/2019 [56997.639808] RIP: 0010:cnl_get_procmon_ref_values+0xc9/0xf0 [i915] [56997.639808] Code: 2c a0 85 c9 74 e0 81 f9 00 00 00 01 75 09 48 c7 c0 0c a4 2c a0 eb cf 48 c7 c6 3c 3a 31 a0 48 c7 c7 40 3a 31 a0 e8 6b 4d ea e0 <0f> 0b 48 c7 c0 00 a4 2c a0 eb b1 48 c7 c0 24 a4 2 c a0 eb a8 e8 be [56997.639808] RSP: 0018:ffffc9000068f8a8 EFLAGS: 00010286 [56997.639808] RAX: 0000000000000000 RBX: ffff88848fa90000 RCX: 0000000000000000 [56997.639808] RDX: ffff8884a08b5ef8 RSI: ffff8884a08a6658 RDI: 00000000ffffffff [56997.639808] RBP: 0000000000000002 R08: 0000000000000000 R09: 0000000000000000 [56997.639808] R10: 0000000000000000 R11: 0000000000000000 R12: ffff88848fa90000 [56997.639808] R13: 0000000000000000 R14: 0000000000000002 R15: 0006c00000162000 [56997.639808] FS: 00007f61ca3d12c0(0000) GS:ffff8884a0880000(0000) knlGS:0000000000000000 [56997.639808] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [56997.639808] CR2: 00007f71be6a92c0 CR3: 0000000494750006 CR4: 0000000000760ee0 [56997.639808] PKRU: 55555554 [56997.639808] Call Trace: [56997.639808] cnl_verify_procmon_ref_values+0x36/0xf0 [i915] [56997.639808] ? rcu_read_lock_sched_held+0x6f/0x80 [56997.639808] ? gen11_fwtable_read32+0x257/0x290 [i915] [56997.639808] icl_combo_phy_verify_state.part.0+0x22/0xa0 [i915] [56997.639808] intel_combo_phy_init+0x17e/0x3e0 [i915] [56997.639808] ? icl_display_core_init+0x2c/0x1a0 [i915] [56997.639808] ? _raw_spin_unlock_irqrestore+0x4c/0x60 [56997.639808] icl_display_core_init+0x34/0x1a0 [i915] [56997.639808] intel_power_domains_init_hw+0x200/0x570 [i915] [56997.639808] i915_driver_probe+0x103b/0x17e0 [i915] [56997.639808] ? printk+0x53/0x6a [56997.639808] i915_pci_probe+0x3b/0x190 [i915] We may or may not need to change the implementation to account for DDIC being available on other SKUs.
