| | * mm, drm/ttm: Fix vm page protection handlingThomas Hellstrom2020-01-161-7/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TTM graphics buffer objects may, transparently to user-space, move between IO and system memory. When that happens, all PTEs pointing to the old location are zapped before the move and then faulted in again if needed. When that happens, the page protection caching mode- and encryption bits may change and be different from those of struct vm_area_struct::vm_page_prot. We were using an ugly hack to set the page protection correctly. Fix that and instead export and use vmf_insert_mixed_prot() or use vmf_insert_pfn_prot(). Also get the default page protection from struct vm_area_struct::vm_page_prot rather than using vm_get_page_prot(). This way we catch modifications done by the vm system for drivers that want write-notification.

In the core, we allow clk_ops::init() to return an error code now so that we can fail clk registration if the callback does something like fail to allocate memory. We also add a new "terminate" clk_op so that things done in clk_ops::init() can be undone, e.g. free memory. We also spit out a warning now when critical clks fail to enable and we support changing clk rates and enable/disable state through debugfs when developers compile the kernel themselves. On the driver front, we get support for what seems like a lot of Qualcomm and NXP SoCs given that those vendors dominate the diffstat. There are a couple new drivers for Xilinx and Amlogic SoCs too. The updates are all small things like fixing the way glitch free muxes switch parents, avoiding div-by-zero problems, or fixing data like parent names. See the updates section below for more details. Finally, the "basic" clk types have been converted to support specifying parents with clk_hw pointers. This work includes an overhaul of the fixed-rate clk type to be more modern by using clk_hw APIs. Core: - Let clk_ops::init() return an error code - Add a clk_ops::terminate() callback to undo clk_ops::init() - Warn about critical clks that fail to enable or prepare - Support dangerous debugfs actions on clks with dead code New Drivers: - Support for Xilinx Versal platform clks - Display clk controller on qcom sc7180 - Video clk controller on qcom sc7180 - Graphics clk controller on qcom sc7180 - CPU PLLs for qcom msm8916 - Move qcom msm8974 gfx3d clk to RPM control - Display port clk support on qcom sdm845 SoCs - Global clk controller on qcom ipq6018 - Add a driver for BCLK of Freescale SAI cores - Add cam, vpe and sgx clock support for TI dra7 - Add aess clock support for TI omap5 - Enable clks for CPUfreq on Allwinner A64 SoCs - Add Amlogic meson8b DDR clock controller - Add input clocks to Amlogic meson8b controllers - Add SPIBSC (SPI FLASH) clock on Renesas RZ/A2 - i.MX8MP clk driver support Updates: - Convert gpio, fixed-factor, mux, gate, divider basic clks to hw based APIs - Detect more PRMCU variants in ux500 driver - Adjust the composite clk type to new way of describing clk parents - Fixes for clk controllers on qcom msm8998 SoCs - Fix gmac main clock for TI dra7 - Move TI dra7-atl clock header to correct location - Fix hidden node name dependency on TI clkctrl clocks - Fix Amlogic meson8b mali clock update using the glitch free mux - Fix Amlogic pll driver division by zero at init - Prepare for split of Renesas R-Car H3 ES1.x and ES2.0+ config symbols - Switch more i.MX clk drivers to clk_hw based APIs - Disable non-functional divider between pll4_audio_div and pll4_post_div on imx6q - Fix watchdog2 clock name typo in imx7ulp clock driver - Set CLK_GET_RATE_NOCACHE flag for DRAM related clocks on i.MX8M SoCs - Suppress bind attrs for i.MX8M clock driver - Add a big comment in imx8qxp-lpcg driver to tell why devm_platform_ioremap_resource() shouldn't be used for the driver - A correction on i.MX8MN usb1_ctrl parent clock setting" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (140 commits) dt/bindings: clk: fsl,plldig: Drop 'bindings' from schema id clk: ls1028a: Fix warning on clamp() usage clk: qoriq: add ls1088a hwaccel clocks support clk: ls1028a: Add clock driver for Display output interface dt/bindings: clk: Add YAML schemas for LS1028A Display Clock bindings clk: fsl-sai: new driver dt-bindings: clock: document the fsl-sai driver clk: composite: add _register_composite_pdata() variants clk: qcom: rpmh: Sort OF match table dt-bindings: fix warnings in validation of qcom,gcc.yaml dt-binding: fix compilation error of the example in qcom,gcc.yaml clk: zynqmp: Add support for clock with CLK_DIVIDER_POWER_OF_TWO flag clk: zynqmp: Fix divider calculation clk: zynqmp: Add support for get max divider clk: zynqmp: Warn user if clock user are more than allowed clk: zynqmp: Extend driver for versal dt-bindings: clock: Add bindings for versal clock driver clk: ti: clkctrl: Fix hidden dependency to node name clk: ti: add clkctrl data dra7 sgx clk: ti: omap5: Add missing AESS clock ...
| * | | clk: mux: Add support for specifying parents via DT/pointersStephen Boyd2020-01-062-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After commit fc0c209c147f ("clk: Allow parents to be specified without string names") we can use DT or direct clk_hw pointers to specify parents. Create a generic function that shouldn't be used very often to encode the multitude of ways of registering a mux clk with different parent information. Then add a bunch of wrapper macros that only pass down what needs to be passed down to the generic function to support this with less arguments. Note: the msm drm driver passes an anonymous array through the macro which seems to confuse my compiler. Adding a parenthesis around the whole thing at the call site seems to fix it but it must be wrong. Maybe it's better to split this patch and pick out the array bits there?

| * | | | drm/via: set FOLL_PIN via pin_user_pages_fast()John Hubbard2020-01-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert drm/via to use the new pin_user_pages_fast() call, which sets FOLL_PIN. Setting FOLL_PIN is now required for code that requires tracking of pinned pages, and therefore for any code that calls put_user_page(). In partial anticipation of this work, the drm/via driver was already calling put_user_page() instead of put_page(). Therefore, in order to convert from the get_user_pages()/put_page() model, to the pin_user_pages()/put_user_page() model, the only change required is to change get_user_pages() to pin_user_pages().

This allows us more reliable hotplug notification and ELD transfer without accessing HD-audio bus; it's more efficient, and more importantly, it works without waking up the runtime PM. The implementation is rather simplistic: nouveau driver provides the get_eld ops for HD-audio, and it notifies the audio hotplug via pin_eld_notify callback upon each nv50_audio_enable() and _disable() call. As the HD-audio pin assignment seems corresponding to the CRTC, the crtc->index number is passed directly as the zero-based port number. The bind and unbind callbacks handle the device-link so that it assures the PM call order.

Namely DRM_AUTH will not be a requirement for DRM_RENDER_ALLOW ioctls. Since vmwgfx does isolation for primary clients in different master realms, the DRM_AUTH can be dropped. The only place where authentication matters, is surface_reference ioctls whenever a legacy (non-prime) handle is used. For those ioctls we call vmw_surface_handle_reference(), where we explicitly check if the client is both a) master and b) unauthenticated - bailing out as result. Otherwise the usual isolation path kicks in and we're all good. v2: Reword commit message, since the isolation work has landed.

To accommodate this change, LANE_CTRL register should be read and bit wise ORed to enable non continuous clock mode. Without this change, if register is written directly, HS signalling will be disabled resulting in black screen. Changes in v1: -Update LANE_CTRL register value Changes in v2: -Changing commit message accordingly.
