+ * call: "cat file > /sys/class/drm/card0/device/hdcp_srm" from usermode no matter what the size is

+ * The kernel can only send PAGE_SIZE at once and since MAX_SRM_FILE(5120) > PAGE_SIZE(4096),

+ *
+ * sysfs interface doesn't tell us the size we will get so we are sending partial SRMs to psp and on
+ * the last call we will send the full SRM. PSP will fail on every call before the last.
+ *
+ * This means we don't know if the SRM is good until the last call. And because of this limitation we
+ * cannot throw errors early as it will stop the kernel from writing to sysfs
+ *
+ * Example 1:
+ * 	Good SRM size = 5096
+ * 	first call to write 4096 -> PSP fails
+ * 	Second call to write 1000 -> PSP Pass -> SRM is set

+ * Solution?:
+ * 	1: Parse the SRM? -> It is signed so we don't know the EOF
+ * 	2: We can have another sysfs that passes the size before calling set. -> simpler solution

+ *
+ * Currently when the system goes down (suspend/shutdown) the SRM is cleared from PSP. For HDCP we need

+ * -The kernel cannot write to the file systems.
+ * -So we need usermode to do this for us, which is why an interface for usermode is needed
+ *
+ *
+ *
+ * Usermode can read/write to/from PSP using the sysfs interface

 /**
- * DOC: bridge callbacks
+ * DOC: bridge operations
+ *
+ * Bridge drivers expose operations through the &drm_bridge_funcs structure.
+ * The DRM internals (atomic and CRTC helpers) use the helpers defined in
+ * drm_bridge.c to call bridge operations. Those operations are divided in
+ * three big categories to support different parts of the bridge usage.
+ *
+ * - The encoder-related operations support control of the bridges in the
+ *   chain, and are roughly counterparts to the &drm_encoder_helper_funcs
+ *   operations. They are used by the legacy CRTC and the atomic modeset
+ *   helpers to perform mode validation, fixup and setting, and enable and
+ *   disable the bridge automatically.
+ *
+ *   The enable and disable operations are split in
+ *   &drm_bridge_funcs.pre_enable, &drm_bridge_funcs.enable,
+ *   &drm_bridge_funcs.disable and &drm_bridge_funcs.post_disable to provide
+ *   finer-grained control.
+ *
+ *   Bridge drivers may implement the legacy version of those operations, or
+ *   the atomic version (prefixed with atomic\_), in which case they shall also
+ *   implement the atomic state bookkeeping operations
+ *   (&drm_bridge_funcs.atomic_duplicate_state,
+ *   &drm_bridge_funcs.atomic_destroy_state and &drm_bridge_funcs.reset).
+ *   Mixing atomic and non-atomic versions of the operations is not supported.
+ *
+ * - The bus format negotiation operations
+ *   &drm_bridge_funcs.atomic_get_output_bus_fmts and
+ *   &drm_bridge_funcs.atomic_get_input_bus_fmts allow bridge drivers to
+ *   negotiate the formats transmitted between bridges in the chain when
+ *   multiple formats are supported. Negotiation for formats is performed
+ *   transparently for display drivers by the atomic modeset helpers. Only
+ *   atomic versions of those operations exist, bridge drivers that need to
+ *   implement them shall thus also implement the atomic version of the
+ *   encoder-related operations. This feature is not supported by the legacy
+ *   CRTC helpers.
+ *
+ * - The connector-related operations support implementing a &drm_connector
+ *   based on a chain of bridges. DRM bridges traditionally create a
+ *   &drm_connector for bridges meant to be used at the end of the chain. This
+ *   puts additional burden on bridge drivers, especially for bridges that may
+ *   be used in the middle of a chain or at the end of it. Furthermore, it
+ *   requires all operations of the &drm_connector to be handled by a single
+ *   bridge, which doesn't always match the hardware architecture.
+ *
+ *   To simplify bridge drivers and make the connector implementation more
+ *   flexible, a new model allows bridges to unconditionally skip creation of
+ *   &drm_connector and instead expose &drm_bridge_funcs operations to support
+ *   an externally-implemented &drm_connector. Those operations are
+ *   &drm_bridge_funcs.detect, &drm_bridge_funcs.get_modes,
+ *   &drm_bridge_funcs.get_edid, &drm_bridge_funcs.hpd_notify,
+ *   &drm_bridge_funcs.hpd_enable and &drm_bridge_funcs.hpd_disable. When
+ *   implemented, display drivers shall create a &drm_connector instance for
+ *   each chain of bridges, and implement those connector instances based on
+ *   the bridge connector operations.
  *
- * The &drm_bridge_funcs ops are populated by the bridge driver. The DRM
- * internals (atomic and CRTC helpers) use the helpers defined in drm_bridge.c
- * These helpers call a specific &drm_bridge_funcs op for all the bridges
- * during encoder configuration.
+ *   Bridge drivers shall implement the connector-related operations for all
+ *   the features that the bridge hardware support. For instance, if a bridge
+ *   supports reading EDID, the &drm_bridge_funcs.get_edid shall be
+ *   implemented. This however doesn't mean that the DDC lines are wired to the
+ *   bridge on a particular platform, as they could also be connected to an I2C
+ *   controller of the SoC. Support for the connector-related operations on the
+ *   running platform is reported through the &drm_bridge.ops flags. Bridge
+ *   drivers shall detect which operations they can support on the platform
+ *   (usually this information is provided by ACPI or DT), and set the
+ *   &drm_bridge.ops flags for all supported operations. A flag shall only be
+ *   set if the corresponding &drm_bridge_funcs operation is implemented, but
+ *   an implemented operation doesn't necessarily imply that the corresponding
+ *   flag will be set. Display drivers shall use the &drm_bridge.ops flags to
+ *   decide which bridge to delegate a connector operation to. This mechanism
+ *   allows providing a single static const &drm_bridge_funcs instance in
+ *   bridge drivers, improving security by storing function pointers in
+ *   read-only memory.
  *
- * For detailed specification of the bridge callbacks see &drm_bridge_funcs.
+ *   In order to ease transition, bridge drivers may support both the old and
+ *   new models by making connector creation optional and implementing the
+ *   connected-related bridge operations. Connector creation is then controlled
+ *   by the flags argument to the drm_bridge_attach() function. Display drivers
+ *   that support the new model and create connectors themselves shall set the
+ *   %DRM_BRIDGE_ATTACH_NO_CONNECTOR flag, and bridge drivers shall then skip
+ *   connector creation. For intermediate bridges in the chain, the flag shall
+ *   be passed to the drm_bridge_attach() call for the downstream bridge.
+ *   Bridge drivers that implement the new model only shall return an error
+ *   from their &drm_bridge_funcs.attach handler when the
+ *   %DRM_BRIDGE_ATTACH_NO_CONNECTOR flag is not set. New display drivers
+ *   should use the new model, and convert the bridge drivers they use if
+ *   needed, in order to gradually transition to the new model.

+ * Negotiation starts by retrieving supported output bus formats on the last

+ * support transcoding into a specific output format -ENOTSUPP is returned and
+ * the next bridge element will have to try a different format. If none of the
+ * combinations worked, -ENOTSUPP is returned and the atomic modeset will fail.
+ *
+ * This implementation is relying on

+ * When &drm_bridge_funcs.atomic_get_input_bus_fmts() is not implemented,

+/**
+ * DOC: overview
+ *
+ * The DRM bridge connector helper object provides a DRM connector
+ * implementation that wraps a chain of &struct drm_bridge. The connector
+ * operations are fully implemented based on the operations of the bridges in
+ * the chain, and don't require any intervention from the display controller
+ * driver at runtime.
+ *
+ * To use the helper, display controller drivers create a bridge connector with
+ * a call to drm_bridge_connector_init(). This associates the newly created
+ * connector with the chain of bridges passed to the function and registers it
+ * with the DRM device. At that point the connector becomes fully usable, no
+ * further operation is needed.
+ *
+ * The DRM bridge connector operations are implemented based on the operations
+ * provided by the bridges in the chain. Each connector operation is delegated
+ * to the bridge closest to the connector (at the end of the chain) that
+ * provides the relevant functionality.
+ *
+ * To make use of this helper, all bridges in the chain shall report bridge
+ * operation flags (&drm_bridge->ops) and bridge output type
+ * (&drm_bridge->type), as well as the DRM_BRIDGE_ATTACH_NO_CONNECTOR attach
+ * flag (none of the bridges shall create a DRM connector directly).

+ *                                               helper
+ * @crtc: CRTC whose vblank timestamp to retrieve
+ * @max_error: Desired maximum allowable error in timestamps (nanosecs)
+ *             On return contains true maximum error of timestamp
+ * @vblank_time: Pointer to time which should receive the timestamp
+ * @in_vblank_irq:
+ *     True when called from drm_crtc_handle_vblank().  Some drivers
+ *     need to apply some workarounds for gpu-specific vblank irq quirks
+ *     if flag is set.
+ *
+ * Implements calculation of exact vblank timestamps from given drm_display_mode
+ * timings and current video scanout position of a CRTC. This can be directly
+ * used as the &drm_crtc_funcs.get_vblank_timestamp implementation of a kms
+ * driver if &drm_crtc_helper_funcs.get_scanout_position is implemented.
+ *
+ * The current implementation only handles standard video modes. For double scan
+ * and interlaced modes the driver is supposed to adjust the hardware mode
+ * (taken from &drm_crtc_state.adjusted mode for atomic modeset drivers) to
+ * match the scanout position reported.
+ *
+ * Note that atomic drivers must call drm_calc_timestamping_constants() before
+ * enabling a CRTC. The atomic helpers already take care of that in
+ * drm_atomic_helper_update_legacy_modeset_state().
+ *
+ * Returns:
+ *
+ * Returns true on success, and false on failure, i.e. when no accurate
+ * timestamp could be acquired.

+ * structures); if we hit such a problem during driver load we're broken even
+ * without GuC, so there is no point in trying to fall back.
+ *
+ * Given the above, we can be in one of 4 states, with the last one implying
+ * we're committed to using the microcontroller:
+ * - Not supported: not available in HW and/or firmware not defined.
+ * - Supported: available in HW and firmware defined.

- * Save all Gunit registers that may be lost after a D3 and a subsequent

- * registers in the following way:
- * - Driver: saved/restored by the driver
- * - Punit : saved/restored by the Punit firmware
- * - No, w/o marking: no need to save/restore, since the register is R/O or
- *                    used internally by the HW in a way that doesn't depend
- *                    keeping the content across a suspend/resume.
- * - Debug : used for debugging
- *
- * We save/restore all registers marked with 'Driver', with the following
- * exceptions:
- * - Registers out of use, including also registers marked with 'Debug'.
- *   These have no effect on the driver's operation, so we don't save/restore
- *   them to reduce the overhead.
- * - Registers that are fully setup by an initialization function called from
- *   the resume path. For example many clock gating and RPS/RC6 registers.
- * - Registers that provide the right functionality with their reset defaults.
- *
- * TODO: Except for registers that based on the above 3 criteria can be safely
- * ignored, we save/restore all others, practically treating the HW context as
- * a black-box for the driver. Further investigation is needed to reduce the
- * saved/restored registers even further, by following the same 3 criteria.

+ * - Driver: saved/restored by the driver
+ * - Punit : saved/restored by the Punit firmware
+ * - No, w/o marking: no need to save/restore, since the register is R/O or
+ *                    used internally by the HW in a way that doesn't depend
+ *                    keeping the content across a suspend/resume.
+ * - Debug : used for debugging
+ *
+ * We save/restore all registers marked with 'Driver', with the following
+ * exceptions:
+ * - Registers out of use, including also registers marked with 'Debug'.
+ *   These have no effect on the driver's operation, so we don't save/restore
+ *   them to reduce the overhead.
+ * - Registers that are fully setup by an initialization function called from
+ *   the resume path. For example many clock gating and RPS/RC6 registers.
+ * - Registers that provide the right functionality with their reset defaults.
+ *
+ * TODO: Except for registers that based on the above 3 criteria can be safely
+ * ignored, we save/restore all others, practically treating the HW context as
+ * a black-box for the driver. Further investigation is needed to reduce the
+ * saved/restored registers even further, by following the same 3 criteria.

+ * Copyright (C) 2020 Linus Walleij <linus.walleij@linaro.org>
+ * Based on code by Robert Teather (C) 2012 Samsung
+ *
+ * This display driver (and I refer to the physical component NT35510,
+ * not this Linux kernel software driver) can handle:
+ * 480x864, 480x854, 480x800, 480x720 and 480x640 pixel displays.
+ * It has 480x840x24bit SRAM embedded for storing a frame.
+ * When powered on the display is by default in 480x800 mode.
+ *
+ * The actual panels using this component have different names, but
+ * the code needed to set up and configure the panel will be similar,
+ * so they should all use the NT35510 driver with appropriate configuration
+ * per-panel, e.g. for physical size.
+ *
+ * This driver is for the DSI interface to panels using the NT35510.
+ *
+ * The NT35510 can also use an RGB (DPI) interface combined with an
+ * I2C or SPI interface for setting up the NT35510. If this is needed
+ * this panel driver should be refactored to also support that use
+ * case.

+ * 0x03FF being the highest voltage.
+ *
+ * Each value must be strictly higher than the previous value forming

  * FIFO Synchronization Registers
  *
- *  This explains the relationship between the various FIFO
- *  sync-related registers in IOSpace and in FIFO space.
- *
  *  SVGA_REG_SYNC --
  *
- *       The SYNC register can be used in two different ways by the guest:
- *
- *         1. If the guest wishes to fully sync (drain) the FIFO,
- *            it will write once to SYNC then poll on the BUSY
- *            register. The FIFO is sync'ed once BUSY is zero.
- *
- *         2. If the guest wants to asynchronously wake up the host,
- *            it will write once to SYNC without polling on BUSY.
- *            Ideally it will do this after some new commands have
- *            been placed in the FIFO, and after reading a zero
- *            from SVGA_FIFO_BUSY.
- *
- *       (1) is the original behaviour that SYNC was designed to
- *       support.  Originally, a write to SYNC would implicitly
- *       trigger a read from BUSY. This causes us to synchronously
- *       process the FIFO.
- *
- *       This behaviour has since been changed so that writing SYNC
- *       will *not* implicitly cause a read from BUSY. Instead, it
- *       makes a channel call which asynchronously wakes up the MKS
- *       thread.
- *
- *       New guests can use this new behaviour to implement (2)
- *       efficiently. This lets guests get the host's attention
- *       without waiting for the MKS to poll, which gives us much
- *       better CPU utilization on SMP hosts and on UP hosts while
- *       we're blocked on the host GPU.
- *
- *       Old guests shouldn't notice the behaviour change. SYNC was
- *       never guaranteed to process the entire FIFO, since it was
- *       bounded to a particular number of CPU cycles. Old guests will
- *       still loop on the BUSY register until the FIFO is empty.
- *
- *       Writing to SYNC currently has the following side-effects:
- *
- *         - Sets SVGA_REG_BUSY to TRUE (in the monitor)
- *         - Asynchronously wakes up the MKS thread for FIFO processing
- *         - The value written to SYNC is recorded as a "reason", for
- *           stats purposes.
- *
- *       If SVGA_FIFO_BUSY is available, drivers are advised to only
- *       write to SYNC if SVGA_FIFO_BUSY is FALSE. Drivers should set
- *       SVGA_FIFO_BUSY to TRUE after writing to SYNC. The MKS will
- *       eventually set SVGA_FIFO_BUSY on its own, but this approach
- *       lets the driver avoid sending multiple asynchronous wakeup
- *       messages to the MKS thread.
+ *       The SYNC register can be used by the guest driver to signal to the
+ *       device that the guest driver is waiting for previously submitted
+ *       commands to complete.
+ *
+ *       When the guest driver writes to the SYNC register, the device sets
+ *       the BUSY register to TRUE, and starts processing the submitted commands
+ *       (if it was not already doing so).  When all previously submitted
+ *       commands are finished and the device is idle again, it sets the BUSY
+ *       register back to FALSE.  (If the guest driver submits new commands
+ *       after writing the SYNC register, the new commands are not guaranteed
+ *       to have been procesesd.)
+ *
+ *       When guest drivers are submitting commands using the FIFO, the device
+ *       periodically polls to check for new FIFO commands when idle, which may
+ *       introduce a delay in command processing.  If the guest-driver wants
+ *       the commands to be processed quickly (which it typically does), it
+ *       should write SYNC after each batch of commands is committed to the
+ *       FIFO to immediately wake up the device.  For even better performance,
+ *       the guest can use the SVGA_FIFO_BUSY register to avoid these extra
+ *       SYNC writes if the device is already active, using the technique known
+ *       as "Ringing the Doorbell" (described below).  (Note that command
+ *       buffer submission implicitly wakes up the device, and so doesn't
+ *       suffer from this problem.)
+ *
+ *       The SYNC register can also be used in combination with BUSY to
+ *       synchronously ensure that all SVGA commands are processed (with both
+ *       the FIFO and command-buffers).  To do this, the guest driver should
+ *       write to SYNC, and then loop reading BUSY until BUSY returns FALSE.
+ *       This technique is known as a "Legacy Sync".
  *
  *  SVGA_REG_BUSY --
  *
  *       This register is set to TRUE when SVGA_REG_SYNC is written,
- *       and it reads as FALSE when the FIFO has been completely
- *       drained.
- *
- *       Every read from this register causes us to synchronously
- *       process FIFO commands. There is no guarantee as to how many
- *       commands each read will process.
+ *       and is set back to FALSE when the device has finished processing
+ *       all commands and is idle again.
  *
- *       CPU time spent processing FIFO commands will be billed to
- *       the guest.
+ *       Every read from the BUSY reigster will block for an undefined
+ *       amount of time (normally until the device finishes some interesting
+ *       work unit), or the device is idle.
  *
- *       New drivers should avoid using this register unless they
- *       need to guarantee that the FIFO is completely drained. It
- *       is overkill for performing a sync-to-fence. Older drivers
- *       will use this register for any type of synchronization.
+ *       Guest drivers can also do a partial Legacy Sync to check for some
+ *       particular condition, for instance by stopping early when a fence
+ *       passes before BUSY has been set back to FALSE.  This is particularly
+ *       useful if the guest-driver knows that it is blocked waiting on the
+ *       device, because it will yield CPU time back to the host.
  *
  *  SVGA_FIFO_BUSY --
  *
- *       This register is a fast way for the guest driver to check
- *       whether the FIFO is already being processed. It reads and
- *       writes at normal RAM speeds, with no monitor intervention.
- *
- *       If this register reads as TRUE, the host is guaranteeing that
- *       any new commands written into the FIFO will be noticed before
- *       the MKS goes back to sleep.
+ *       The SVGA_FIFO_BUSY register is a fast way for the guest driver to check
+ *       whether the device is actively processing FIFO commands before writing
+ *       the more expensive SYNC register.
  *
- *       If this register reads as FALSE, no such guarantee can be
- *       made.
+ *       If this register reads as TRUE, the device is actively processing
+ *       FIFO commands.
  *
- *       The guest should use this register to quickly determine
- *       whether or not it needs to wake up the host. If the guest
- *       just wrote a command or group of commands that it would like
- *       the host to begin processing, it should:
+ *       If this register reads as FALSE, the device may not be actively
+ *       processing commands, and the guest driver should try
+ *       "Ringing the Doorbell".
  *
- *         1. Read SVGA_FIFO_BUSY. If it reads as TRUE, no further
- *            action is necessary.
+ *       To Ring the Doorbell, the guest should:
  *
- *         2. Write TRUE to SVGA_FIFO_BUSY. This informs future guest
- *            code that we've already sent a SYNC to the host and we
- *            don't need to send a duplicate.
+ *       1. Have already written their batch of commands into the FIFO.
+ *       2. Check if the SVGA_FIFO_BUSY register is available by reading
+ *          SVGA_FIFO_MIN.
+ *       3. Read SVGA_FIFO_BUSY.  If it reads as TRUE, the device is actively
+ *          processing FIFO commands, and no further action is necessary.
+ *       4. If SVGA_FIFO_BUSY was FALSE, write TRUE to SVGA_REG_SYNC.
  *
- *         3. Write a reason to SVGA_REG_SYNC. This will send an
- *            asynchronous wakeup to the MKS thread.
+ *       For maximum performance, this procedure should be followed after
+ *       every meaningful batch of commands has been written into the FIFO.
+ *       (Normally when the underlying application signals it's finished a
+ *       meaningful work unit by calling Flush.)
