For example, use 'struct mdp5_smp *' everywhere instead of 'void *', but only declare it as 'struct mdp5_smp;' in common headers, so the struct body is still private. The accomplishes the desired modularity while still letting the compiler provide some type checking for us. Signed-off-by: -

MDP5 currently support one single CRTC with its private pipe. This change allows the configuration of multiple CRTCs with the possibility to attach several public planes to these CRTCs. Signed-off-by:

The hardware configuration modification from a version to another is quite consequent. Introducing a configuration module (mdp5_cfg) may make things more clear and easier to access when a new hardware version comes up. Signed-off-by:

The Shared Memory Pool (SMP) has its own limitation, features and state. Some examples are: - the number of Memory Macro Block (MMB) and their size - the number of lines that can be fetched - the state of MMB currently allocated - the computation of number of blocks required per plane - client IDs ... In order to avoid private data to be overwritten by other modules, let's make these private to the SMP module. Some of these depend on the hardware configuration, let's add them to the mdp5_config struct. In some hw configurations, some MMBs are statically tied to RGB pipes and cannot be re-allocated dynamically. This change introduces the concept of MMB static usage and makes sure that dynamic MMB requests are dimensioned accordingly. A note on passing a pipe pointer, instead of client IDs: Client IDs are SMP-related information. Passing PIPE information to SMP lets SMP module to find out which SMP client(s) are used. This allows the SMP module to access the PIPE pointer, which can be used for FIFO watermark configuration. By the way, even though REG_MDP5_PIPE_REQPRIO_FIFO_WM_* registers are part of the PIPE registers, their functionality is to reflect the behavior of the SMP block. These registers access is now restricted to the SMP module. Signed-off-by:

A left-over from prior to component framework. The original intent was to deal with hdmi getting unloaded before the master component, but that isn't really going to work anyways. These days with the component framework taking care to unload the master component first, we don't have to worry about this. Signed-off-by: -

The core clock rate depends on the hw configuration. Once we have read the hardware revision, we can set the core clock to its maximum value. Before then, the clock is set at a rate supported by all MDP5 revisions. Signed-off-by:

For mdp5, the irqs of hdmi/eDP/dsi0/dsi1 blocks get routed through the mdp block. In order to decouple hdmi/eDP/etc, register an irq domain in mdp5. When hdmi/dsi/etc are used with mdp4, they can directly setup their irqs in their DT nodes as normal. When used with mdp5, instead set the mdp device as the interrupt-parent, as in: mdp: qcom,mdss_mdp@fd900000 { compatible = "qcom,mdss_mdp"; interrupt-controller; #interrupt-cells = <1>; ... }; hdmi: qcom,hdmi_tx@fd922100 { compatible = "qcom,hdmi-tx-8074"; interrupt-parent = <&mdp>; interrupts = <8 0>; /* MDP5_HW_INTR_STATUS.INTR_HDMI */ ... }; There is a slight awkwardness, in that we cannot disable child irqs at the mdp level, they can only be cleared in the child block. So you must not use threaded irq handlers in the child. I'm not sure if there is a better way to deal with that. Signed-off-by: -

It happens on occasion that developers of generic user-space applications abuse the dumb buffer API to get hold of drm buffers that they can both mmap() and use for GPU acceleration, using the assumptions that dumb buffers and buffers available for GPU are a) The same type and can be aribtrarily type-casted. b) fully coherent. This patch makes the most widely used drivers warn nicely when that happens, the next step will be to fail. v2: Move drmP.h changes to drm_gem.h. Fix Radeon dumb mmap breakage. Signed-off-by:

The cursor_set2 hook provides the cursor hotspot position within the cursor image. When the hotspot position changes, we can adjust the cursor position such that the hotspot doesn't move on the screen. This prevents the cursor from appearing to intermittently jump around on the screen when the position of the hotspot within the cursor image changes. Reviewed-by:
