But per spec the komeda HW only has three input clks: - ACLK: used for AXI masters, APB slave and most pipeline processing - PXCLK for pipeline 0: output pixel clock for pipeline 0 - PXCLK for pipeline 1: output pixel clock for pipeline 1 So one ACLK is enough, no need to split it to three mclk/pclk/axiclk.

2019-06-13drm: Add helpers to kick off self refresh mode in driversSean Paul1-0/+9
This patch adds a new drm helper library to help drivers implement self refresh. Drivers choosing to use it will register crtcs and will receive callbacks when it's time to enter or exit self refresh mode. In its current form, it has a timer which will trigger after a driver-specified amount of inactivity. When the timer triggers, the helpers will submit a new atomic commit to shut the refreshing pipe off. On the next atomic commit, the drm core will revert the self refresh state and bring everything back up to be actively driven. From the driver's perspective, this works like a regular disable/enable cycle. The driver need only check the 'self_refresh_active' state in crtc_state. It should initiate self refresh mode on the panel and enter an off or low-power state. Changes in v2: - s/psr/self_refresh/ (Daniel) - integrated the psr exit into the commit that wakes it up (Jose/Daniel) - made the psr state per-crtc (Jose/Daniel) Changes in v3: - Remove the self_refresh_(active|changed) from connector state (Daniel) - Simplify loop in drm_self_refresh_helper_alter_state (Daniel) - Improve self_refresh_aware comment (Daniel) - s/self_refresh_state/self_refresh_data/ (Daniel) Changes in v4: - Move docbook location below panel (Daniel) - Improve docbook with references and more detailed explanation (Daniel) - Instead of register/unregister, use init/cleanup (Daniel) Changes in v5: - Resolved conflict in drm_atomic_helper.c #include block - Resolved conflict in rst with HDCP helper docs Changes in v6: - Fix include ordering, clean up forward declarations (Sam) Link to v1: https://patchwork.freedesktop.org/patch/msgid/20190228210939.83386-2-sean@poorly.run Link to v2: https://patchwork.freedesktop.org/patch/msgid/20190326204509.96515-1-sean@poorly.run Link to v3: https://patchwork.freedesktop.org/patch/msgid/20190502194956.218441-6-sean@poorly.run Link to v4: https://patchwork.freedesktop.org/patch/msgid/20190508160920.144739-6-sean@poorly.run Link to v5: https://patchwork.freedesktop.org/patch/msgid/20190611160844.257498-6-sean@poorly.run Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Jose Souza <jose.souza@intel.com> Cc: Zain Wang <wzz@rock-chips.com> Cc: Tomasz Figa <tfiga@chromium.org> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Sam Ravnborg <sam@ravnborg.org> Tested-by: Heiko Stuebner <heiko@sntech.de> Reviewed-by: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Sean Paul <seanpaul@chromium.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190612145026.191846-1-sean@poorly.run
2019-06-13arm64/sve: Fix missing SVE/FPSIMD endianness conversionsDave Martin1-0/+16
The in-memory representation of SVE and FPSIMD registers is different: the FPSIMD V-registers are stored as single 128-bit host-endian values, whereas SVE registers are stored in an endianness-invariant byte order. This means that the two representations differ when running on a big-endian host. But we blindly copy data from one representation to another when converting between the two, resulting in the register contents being unintentionally byteswapped in certain situations. Currently this can be triggered by the first SVE instruction after a syscall, for example (though the potential trigger points may vary in future). So, fix the conversion functions fpsimd_to_sve(), sve_to_fpsimd() and sve_sync_from_fpsimd_zeropad() to swab where appropriate. There is no common swahl128() or swab128() that we could use here. Maybe it would be worth making this generic, but for now add a simple local hack. Since the byte order differences are exposed in ABI, also clarify the documentation.

2019-06-05dt-bindings: drm/bridge/synopsys: dw-hdmi: Add "unwedge" for ddc busDouglas Anderson1-0/+7
In certain situations it was seen that we could wedge up the DDC bus on the HDMI adapter on rk3288. The only way to unwedge was to mux one of the pins over to GPIO output-driven-low temporarily and then quickly mux back. Full details can be found in the patch ("drm/bridge/synopsys: dw-hdmi: Add "unwedge" for ddc bus"). Since unwedge requires remuxing the pins, we first need to add to the bindings so that we can specify what state the pins should be in for unwedging.

2019-06-04drm/fb-helper: Remove drm_fb_helper_crtcNoralf Trønnes2-0/+6
struct drm_fb_helper_crtc is now just a wrapper around drm_mode_set so use that directly instead and attach it as a modeset array onto drm_client_dev. drm_fb_helper will use this array to store its modesets which means it will always initialize a drm_client, but it will not register the client (callbacks) unless it's the generic fbdev emulation. Code will later be moved to drm_client, so add code there in a new file drm_client_modeset.c with MIT license to match drm_fb_helper.c. The modeset connector array size is hardcoded for the cloned case to avoid having to pass in a value from the driver. A value of 8 is chosen to err on the safe side. This means that the max connector argument for drm_fb_helper_init() and drm_fb_helper_fbdev_setup() isn't used anymore, a todo entry for this is added. In pan_display_atomic() restore_fbdev_mode_force() is used instead of restore_fbdev_mode_atomic() because that one will later become internal to drm_client_modeset.

2019-06-01mm, memcg: consider subtrees in memory.eventsChris Down1-0/+9
memory.stat and other files already consider subtrees in their output, and we should too in order to not present an inconsistent interface. The current situation is fairly confusing, because people interacting with cgroups expect hierarchical behaviour in the vein of memory.stat, cgroup.events, and other files. For example, this causes confusion when debugging reclaim events under low, as currently these always read "0" at non-leaf memcg nodes, which frequently causes people to misdiagnose breach behaviour. The same confusion applies to other counters in this file when debugging issues. Aggregation is done at write time instead of at read-time since these counters aren't hot (unlike memory.stat which is per-page, so it does it at read time), and it makes sense to bundle this with the file notifications. After this patch, events are propagated up the hierarchy: [root@ktst ~]# cat /sys/fs/cgroup/system.slice/memory.events low 0 high 0 max 0 oom 0 oom_kill 0 [root@ktst ~]# systemd-run -p MemoryMax=1 true Running as unit: run-r251162a189fb4562b9dabfdc9b0422f5.service [root@ktst ~]# cat /sys/fs/cgroup/system.slice/memory.events low 0 high 0 max 7 oom 1 oom_kill 1 As this is a change in behaviour, this can be reverted to the old behaviour by mounting with the `memory_localevents' flag set. However, we use the new behaviour by default as there's a lack of evidence that there are any current users of memory.events that would find this change undesirable. akpm: this is a behaviour change, so Cc:stable. THis is so that forthcoming distros which use cgroup v2 are more likely to pick up the revised behaviour.
