In order for hibernation to reliably work we need to properly turn off the SDMA block, sadly after numerous attemps i haven't not found proper sequence for clean and full shutdown. So simply reset both SDMA block, this makes hibernation works reliably on sea island GPU family (CI) Hibernation and suspend to ram were tested (several times) on : Bonaire Hawaii Mullins Kaveri Kabini Cc: stable@vger.kernel.org Signed-off-by:

In order for hibernation to reliably work we need to cleanup more thoroughly the compute ring. Hibernation is different from suspend resume as when we resume from hibernation the hardware is first fully initialize by regular kernel then freeze callback happens (which correspond to a suspend inside the radeon kernel driver) and turn off each of the block. It turns out we were not cleanly shutting down the compute ring. This patch fix that. Hibernation and suspend to ram were tested (several times) on : Bonaire Hawaii Mullins Kaveri Kabini Changed since v1: - Factor the ring stop logic into a function taking ring as arg.

On the MacBook Pro, power of the gpu is cut by a gmux chip. Sometimes the gpu gets stuck in powersaving mode and refuses to wake up ("Refused to change power state, currently in D3"). Inserting a delay between setting the gpu to D3hot and cutting the power seems to help (most of the time). This issue and its (partial) remediation by the patch was observed with an Nvidia GT650M (NVE7 / GK107). Signed-off-by:Lukas Wunner <lukas@wunner.de> Signed-off-by:

I've only seen this once, and I failed to capture the lockdep backtrace, but I did some investigations. If we are calling into the MST layer from EDID probing, we have the mode_config mutex held, if during that EDID probing, the MST hub goes away, then we can get a deadlock where the connector destruction function in the driver tries to retake the mode config mutex. This offloads connector destruction to a workqueue, and avoid the subsequenct lock ordering issue. Acked-by:

If we are doing an MST transaction and we've gotten HPD and we lookup the device from the incoming msg, we should take the mgr lock around it, so that mst_primary and mstb->ports are valid. Reviewed-by:

This validates the mst_primary under the lock, and then calls into the check and send function. This makes the code a lot easier to understand the locking rules in. Signed-off-by:

Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next Summary: . Add atomic feature support - Exynos also now supports atomic feature. However, it doesn't guarantee atomic operation yet, and is required for more cleanups. This time we just modified for Exynos drm driver to use atomic interfaces instead of legacy ones. Next time, we will enhance Exynos drm driver to support the atomic operation. . Add iommu support - This is a patch series according to below Exynos iommu integration work with DT and dma-mapping subsystem, http://lwn.net/Articles/607626/ . Consolidate Exynos drm driver initialization. - This patch sereis resolves the issue that only the first compoments was bound when happened deferred probing for other pipelines and also makes the driver to be more cleanned up by moving the dispered codes for registering kms drivers to one place. . Add new MIC, DECON drivers, and MIPI-DSI support for Exynos5433. - Add MIC(Mobile image compressor) driver. MIC is a new IP for Exynos5433 and later, which is used to transfer frame data to MIPI-DSI controller compressing the data to reduce memory bandwidth. - Add DECON driver for Exynos5433 SoC. This IP is a dislay controller similar to Exynos7's one but this controller has much different registers from Exynos7's ones so this driver has been implemented separately. We will implement a helper modules for FIMD and two DECON controllers to remove duplicated codes later. - Add Exynos5433 SoC support to MIPI-DSI driver, and device tree relevant patches. * 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos: (50 commits) ARM: dts: rename the clock of MIPI DSI 'pll_clk' to 'sclk_mipi' drm/exynos: dsi: do not set TE GPIO direction by input drm/exynos: dsi: add support for MIC driver as a bridge drm/exynos: dsi: add support for Exynos5433 drm/exynos: dsi: make use of array for clock access drm/exynos: dsi: make use of driver data for static values drm/exynos: dsi: add macros for register access drm/exynos: dsi: rename pll_clk to sclk_clk drm/exynos: mic: add MIC driver of: add helper for getting endpoint node of specific identifiers drm/exynos: add Exynos5433 decon driver drm/exynos: fix the input prompt of Exynos7 DECON drm/exynos: add drm_iommu_attach_device_if_possible() drm/exynos: Add the dependency for DRM_EXYNOS to DPI/DSI/DP drm/exynos: remove the dependency of DP driver for ARCH_EXYNOS drm/exynos: do not wait for vblank at atomic operation drm/exynos: Remove unused vma field of exynos_drm_gem_obj drm/exynos: fimd: fix page fault issue with iommu drm/exynos: iommu: improve a check for non-iommu dma_ops drm/exynos: iommu: detach from default dma-mapping domain on init ...

This patch renames pll_clk to sclk_clk. The clock referenced by pll_clk is actually not the pll input clock for dsi. The pll input clock comes from the board's oscillator directly. But for the backward compatibility, the old clock name "pll_clk" is also OK. Signed-off-by:

MIC(Mobile image compressor) is newly added IP in Exynos5433. MIC resides between decon and mipi dsim, and compresses frame data by 50%. With dsi, not display port, to send frame data to the panel, the bandwidth is not enough. That is why this compressor is introduced. Signed-off-by:

When there are multiple ports or multiple endpoints in a port, they have to be distinguished by the value of reg property. It is common. The drivers can get the specific endpoint in the specific port via this function. Now the drivers have to implement this code in themselves or have to force the order of dt nodes to get the right node. Signed-off-by:
