+/**
+ * DOC: DPIO
+ *
+ * VLV and CHV have slightly peculiar display PHYs for driving DP/HDMI
+ * ports. DPIO is the name given to such a display PHY. These PHYs
+ * don't follow the standard programming model using direct MMIO
+ * registers, and instead their registers must be accessed trough IOSF
+ * sideband. VLV has one such PHY for driving ports B and C, and CHV
+ * adds another PHY for driving port D. Each PHY responds to specific
+ * IOSF-SB port.
+ *
+ * Each display PHY is made up of one or two channels. Each channel
+ * houses a common lane part which contains the PLL and other common
+ * logic. CH0 common lane also contains the IOSF-SB logic for the
+ * Common Register Interface (CRI) ie. the DPIO registers. CRI clock
+ * must be running when any DPIO registers are accessed.
+ *
+ * In addition to having their own registers, the PHYs are also
+ * controlled through some dedicated signals from the display
+ * controller. These include PLL reference clock enable, PLL enable,
+ * and CRI clock selection, for example.
+ *
+ * Eeach channel also has two splines (also called data lanes), and
+ * each spline is made up of one Physical Access Coding Sub-Layer
+ * (PCS) block and two TX lanes. So each channel has two PCS blocks
+ * and four TX lanes. The TX lanes are used as DP lanes or TMDS
+ * data/clock pairs depending on the output type.
+ *
+ * Additionally the PHY also contains an AUX lane with AUX blocks
+ * for each channel. This is used for DP AUX communication, but
+ * this fact isn't really relevant for the driver since AUX is
+ * controlled from the display controller side. No DPIO registers
+ * need to be accessed during AUX communication,
+ *
+ * Generally the common lane corresponds to the pipe and
+ * the spline (PCS/TX) correponds to the port.
+ *
+ * For dual channel PHY (VLV/CHV):
+ *
+ * pipe A == CMN/PLL/REF CH0
+ *
+ * pipe B == CMN/PLL/REF CH1
+ *
+ * port B == PCS/TX CH0
+ *
+ * port C == PCS/TX CH1
+ *
+ * This is especially important when we cross the streams
+ * ie. drive port B with pipe B, or port C with pipe A.
+ *
+ * For single channel PHY (CHV):
+ *
+ * pipe C == CMN/PLL/REF CH0
+ *
+ * port D == PCS/TX CH0
+ *
+ * Note: digital port B is DDI0, digital port C is DDI1,
+ * digital port D is DDI2

+ igdbg: i915 kernel driver tool
+
+Content:
+ 1. Introduction
+ 2. Implementation overview
+ 3. Command summary
+ 4. Command details
+ 5. Reference
+
+
+1. Introduction
+
+igdbg is a standalone user mode tool that can run on a Linux system with
+proper configuration. The primary purpose of this tool is to learn and
+understand i915 GPU driver which is in linux kernel "drivers/gpu/drm/i915"
+folder. It might be also helpful for developers to check or dump GPU states.
+
+The tool must be invoked by root. Usage:
+ igdbg [ -v -d <device name> -c <command> ]
+
+ <device name> is the device that the tool uses to access GPU resources,
+ by default it is /dev/mem
+ <command> is the command to be executed. Without it, the tool enters
+ into interactive mode so that user can type a command later
+
+The tool till now is only tested on a GEN8 based Android device. It only
+adds a few device IDs in the support list, thus it might not work or might
+get different result on other devices.
+
+2. Implementation overview
+
+The tool opens /dev/mem to "mmap" device memory. The memory includes GPU
+mmio space, gtt space and frame buffer. It is the way that the tool dumps
+registers/gtt and frame buffer content. There are some GPU resources that
+are in system memory including PPGTT tables, ring buffers, etc. For them,
+the tool uses "read/write" to access them.
+
+There are two Linux kernel configurations that may forbid "mmap" and
+"read/write" on /dev/mem: CONFIG_X86_PAT and CONFIG_STRICT_DEVMEM. PAT can
+be flagged on or off by "nopat" kernel boot parameter. Check bellow table
+if there are some problems to run the tool:
+
+CONFIG_STRICT_DEVMEM | Y | N
+---------------------+---------------------+-------------------------
+ Allow "mmap" | Usually it is Yes, but may get issue on some
+ on device memory? | systems. Try to add "nopat" if it is the case
+---------------------+---------------------+-------------------------
+ Allow "read/write" | No | Yes
+ on system RAM? | |
+---------------------+---------------------+-------------------------
+
+Sub-folder linux/imem.c is a kernel module of char device. It derives from linux
+kernel "driver/char/mem.c". The difference is that it removes the restrictions
+of CONFIG_STRICT_DEVMEM. When load it into kernel, it registers a char device
+with major number 999. The tool can use this char device instead of /dev/mem to
+"mmap" and "read/write" by command line parameter "-d <device name>". It is for the
+people that don't want to rebuild the kernel to disable STRICT_DEVMEM configuration.
+
+3. Command summary
+
+As mentioned above, "mmap" is used to access mmio/gtt space and frame buffer
+content, and "read/write" is used to access the resources in system memory. From
+this perspective, there are two types of commands:
+
+A. Commands that are supported by "mmap" /dev/mem
+
+ Command | Introduction
+-----------+---------------------------------------------------
+ regread | Read a register
+-----------+---------------------------------------------------
+ regwrite | Write a register
+-----------+---------------------------------------------------
+ dumpgtt | Dump GGTT mappings
+-----------+---------------------------------------------------
+ stolen | Dump stolen memory mappings
+-----------+---------------------------------------------------
+ dumpfb | Dump frame buffer
+-----------+---------------------------------------------------
+ dumpfbl | Dump frame buffer with a fence register,
+ | thus it is linear mode
+-----------+---------------------------------------------------
+ fillfb | Fill frame buffer
+-----------+---------------------------------------------------
+ fillfbl | Fill frame buffer with a fence register,
+ | thus it is linear mode
+-----------+---------------------------------------------------
+ irq | Sample IRQ status
+-----------+---------------------------------------------------
+ cstatus | Sample execlist context status
+-----------+---------------------------------------------------
+
+B. Commands that are supported by "read/write" /dev/mem
+
+ Command | Introduction
+-----------+---------------------------------------------------
+ dumpstat | Dump context stat
+-----------+---------------------------------------------------
+ dumppgtt | Dump PPGTT mappins
+-----------+---------------------------------------------------
+ dumpring | Dump ring buffer and the chained batch buffer
+-----------+---------------------------------------------------
+
+4. Command details
+
+4.1 regread/regwrite
+
+regread <register address>
+regwrite <register address> <register value>
+
+4.2 dumpgtt
+
+GTT table usually shares the PCI BAR0 with mmio space. It locates at the
+half bottom of the space. The real memory behind it actually resides in
+system RAM whose address can be read out from a register
+
+ dumpgtt <offset> <size>
+
+Example:
+ igdbg -c "dumpgtt 2<<20 40<<10"
+
+>>>>>>
+GTT size = 4096K (Can map 2048M memory), location at 0x7c900000 (1993M)
+-----------------------------002M FB------------------------------

+
+Since the onscreen frame buffer is X-tile that the sub-tile block is 512x8,
+the first 512 bytes from "dumpfb" and "dumpfbl" is same, but then the following
+bytes will be different (start from 0x0ac8f200).
+
+Similarly, use command:
+ igdbg -c "fillfb 0xac8f000 4096 0xff"
+ igdbg -c "fillfbl 0xac8f000 4096 0xff"
+
+They will visually display the difference on screen. The first one will display

+The driver may use two engines (thus two rings) for one task, e.g. in above example, the
+encoding uses "render ring" and "bsd ring", and driver may use the same batch buffer for
+the two rings. If the dump is at frame boundary, the instructions in the batch buffer of
+render ring may be overwritten by the instructions of bsd, thus they may be lost and can
+not dump correctly.
