This patch adds support for software clock gating to UVD 5 and UVD 6 blocks with a preliminary commented out hardware gating routine. Currently hardware gating does not work so it's not activated. Signed-off-by:

The values of all but the RADEON_HPD_NONE members of the radeon_hpd_id enum transform 1:1 into bit positions within the 'enabled' bitset as assembled by evergreen_hpd_init(): enabled |= 1 << radeon_connector->hpd.hpd; However, if ->hpd.hpd happens to equal RADEON_HPD_NONE == 0xff, UBSAN reports UBSAN: Undefined behaviour in drivers/gpu/drm/radeon/evergreen.c:1867:16 shift exponent 255 is too large for 32-bit type 'int' [...] Call Trace: [<ffffffff818c4d35>] dump_stack+0xbc/0x117 [<ffffffff818c4c79>] ? _atomic_dec_and_lock+0x169/0x169 [<ffffffff819411bb>] ubsan_epilogue+0xd/0x4e [<ffffffff81941cbc>] __ubsan_handle_shift_out_of_bounds+0x1fb/0x254 [<ffffffffa0ba7f2e>] ? atom_execute_table+0x3e/0x50 [radeon] [<ffffffff81941ac1>] ? __ubsan_handle_load_invalid_value+0x158/0x158 [<ffffffffa0b87700>] ? radeon_get_pll_use_mask+0x130/0x130 [radeon] [<ffffffff81219930>] ? wake_up_klogd_work_func+0x60/0x60 [<ffffffff8121a35e>] ? vprintk_default+0x3e/0x60 [<ffffffffa0c603c4>] evergreen_hpd_init+0x274/0x2d0 [radeon] [<ffffffffa0c603c4>] ? evergreen_hpd_init+0x274/0x2d0 [radeon] [<ffffffffa0bd196e>] radeon_modeset_init+0x8ce/0x18d0 [radeon] [<ffffffffa0b71d86>] radeon_driver_load_kms+0x186/0x350 [radeon] [<ffffffffa03b6b16>] drm_dev_register+0xc6/0x100 [drm] [<ffffffffa03bc8c4>] drm_get_pci_dev+0xe4/0x490 [drm] [<ffffffff814b83f0>] ? kfree+0x220/0x370 [<ffffffffa0b687c2>] radeon_pci_probe+0x112/0x140 [radeon] [...] ===================================================================== radeon 0000:01:00.0: No connectors reported connected with modes At least on x86, there should be no user-visible impact as there 1 << 0xff == 1 << (0xff & 31) == 1 << 31 holds and 31 > RADEON_MAX_HPD_PINS.

this is to fix fatal page fault error that occured if: job is signaled/released after its timeout work is already put to the global queue (in this case the cancel_delayed_work will return false), which will lead to NX-protection error page fault during job_timeout_func. Signed-off-by:

for those jobs submitted through scheduler, do not free it immediately after scheduled, instead free it in global workqueue by its sched fence signaling callback function. v2: call uf's bo_undef after job_run() call job's sync free after job_run() no static inline __amdgpu_job_free() anymore, just use kfree(job) to replace it.

This match the exact same control flow as existing code. It just use goto instead of multiple levels of if/else. It also clarify early initialization failures by clearing rdev->has_vce doing so does not change end result from hardware point of view, it only avoids printing more error messages down the line and thus only the original error is reported.

This adds very rudimentary TCON (timing controller for raw LCD displays) support to enable the bypass mode in order to use the DCU controller on Freescale/NXP Vybrid SoC's. Additionally the register clock and pixel clock has been separated, but are currently still enabled and disabled pairwise. Other than that, fixes and cleanups accross the driver. * 'for-next' of http://git.agner.ch/git/linux-drm-fsl-dcu: drm/fsl-dcu: increment version and date drm/fsl-dcu: implement lastclose callback drm/fsl-dcu: disable output polling on driver unload drm/fsl-dcu: deallocate fbdev CMA on unload drm/fsl-dcu: use variable name dev for struct drm_device drm/fsl-dcu: handle missing panel gracefully drm/fsl-dcu: detach panel on destroy drm/layerscape: reduce excessive stack usage drm/fsl-dcu: add TCON driver drm/fsl-dcu: use common clock framework for pixel clock divider drm/fsl-dcu: add extra clock for pixel clock drm/fsl-dcu: disable clock on initialization failure and remove

Merge tag 'sun4i-drm-for-4.7' of https://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux into drm-next Allwinner DRM driver for 4.7 This pull request introduces the sun4i driver, meant to be used on the older Allwinner SoCs (A10, A13, A20, A23, A31 and A33). It currently supports only the A13, which has one of the simplest video pipeline. Support for other video components and SoCs will be added eventually. It supports only a RGB or composite output. It doesn't do HDMI, VGA, LVDS or power management yet, but that will come in time as well. * tag 'sun4i-drm-for-4.7' of https://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux: MAINTAINERS: Add a maintainer for the Allwinner DRM driver drm: sun4i: tv: Add NTSC output standard drm: sun4i: tv: Add PAL output standard drm: sun4i: Add composite output drm: sun4i: Add RGB output drm: Add Allwinner A10 Display Engine support drm: sun4i: Add DT bindings documentation drm: fb: Add seq_file definition
