lcd-splc780d-4bitmode-board.h Board-specific LCD info for these boards:
Avnet AV110 (XT-AV110)
Xilinx ML605 (XT-ML605)
Xilinx KC705 (XT-KC705)
Interface between board-independent driver and board-specific header.
This is used by a board-independent SPLC780D LCD controller (4 bit mode)
driver to obtain board-specific information about LCD displays on the board,
such as the controller register base address and spacing (a function of how
the address lines are connected on the board) and length of the visible window
of the display (a function of the LCD panel the controller drives).
The driver doesnot refer directly to the board-specific header, which therefore is not
constrained to use macro names consistent with other boards.
!! Must not contain any board-specific macro names (only controller specific) !!
Included at compile-time via an include path specific to the board.
The listed boards contain a single MYTech MOC-16216B-B display driven by
a Sunplus SPLC870D controller.

This is used by board-support-packages with one or more LCD displays that use
a SPLC780D controller in 4 bit mode. A BSP provides a base address for each

Note that LCD display operation is almost totally independent of the LCD

may limit the number of characters of the controller's RAM buffer that are
actually visible at one time. The length of the display's visible window
is not specifified in this controller-specific header, but comes to the
driver from the board-specific "display.h" header.

Bit fields and their values in the instruction register.
These fields are NOT orthogonal - they overlap!
Thus only one field may be written at a time, determined by the
most-significant 1 bit in the pattern (the field selector).
All less significant bits are part of the value of the selected field.
The fields and their values are grouped together to emphasize this format.
Field selector macro names end in '_' (implying something more needs

A single bit field (eg. SPCL780D_INST_HOME) need not have a value.

* System call like services offered by the simulator host.

* The following prototypes describe intrinsic functions
* corresponding to TIE instructions. Some TIE instructions
* may produce multiple results (designated as "out" operands
* in the iclass section) or may have operands used as both
* inputs and outputs (designated as "inout"). However, the C
* and C++ languages do not provide syntax that can express
* the in/out/inout constraints of TIE intrinsics.
* Nevertheless, the compiler understands these constraints
* and will check that the intrinsic functions are used
* correctly. To improve the readability of these prototypes,
* the "out" and "inout" parameters are marked accordingly
* with comments.

Xilinx ML605 (XT-ML605)
Xilinx KC705 (XT-KC705)
Interface between board-independent driver and board-specific header.
This is used by a board-independent 16550 UART driver to obtain board-specific
information about 1 instance of the 16550 UART on the board, such as the device
register base address and spacing (a function of how the address lines are
connected on the board) and the frequency of the UART clock. The driver does
not refer directly to the board-specific header, which therefore is not
constrained to use macro names consistent with other boards.
!! Must not contain any board-specific macro names (only UART specific). !!
Included at compile-time via an include path specific to the board.
These boards contain a single 16550 UART implemented on the FPGA.
Their clock frequency comes from the board's core clock (not its own crystal)
which depends on the core config so is not a constant. Obtained via the BSP.

Mutexes can be normal or recursive. For a normal mutex, a core

deadlock. For a recursive mutex, a core will succeed in acquiring a
mutex it already holds, and must release it as many times as it
acquired it.

// Coprocessor state handling:
// The coprocessor state save area is allocated on the thread stack. The stack
// must be sized appropriately. Threads that do not use coprocessors need not
// allocate the storage area.
//
// Along with the save area for each coprocessor, two bitmasks with flags per
// coprocessor (laid out as in the CPENABLE reg) help manage context switching
// coprocessors as efficiently as possible:
//
// XT_CPENABLE
// The contents of a non-running thread's CPENABLE register.
// It represents the coprocessors owned (and whose state is still needed)
// by the thread. When a thread is preempted, its CPENABLE is saved here.
// When a thread solicits a context switch, its CPENABLE is cleared - the
// compiler has saved the (caller-saved) coprocessor state if needed.
// When a non-running thread loses ownership of a CP, its bit is cleared.
// When a thread runs, it's XT_CPENABLE is loaded into the CPENABLE reg.
// Avoids coprocessor exceptions when no change of ownership is needed.
//
// XT_CPSTORED
// A bitmask with the same layout as CPENABLE, a bit per coprocessor.
// Indicates whether the state of each coprocessor is saved in the state
// save area. When a thread enters the kernel, only the state of coprocs
// still enabled in CPENABLE is saved. When the coprocessor exception
// handler assigns ownership of a coprocessor to a thread, it restores
// the saved state only if this bit is set, and clears this bit.
//
// XT_CP_CS_ST
// A bitmask with the same layout as CPENABLE, a bit per co-processor.
// Indicates whether callee-saved state is saved in the state save area.
// Callee-saved state is saved by itself on a solicited context switch,
// and restored when needed by the coprocessor exception handler.
// Unsolicited switches will cause the entire coprocessor to be saved
// when necessary.
//
// XT_NCP_ASA
// Pointer to aligned save area for non-CP state. This is always filled
// in, even if there is no non-CP state to be saved. If there is no state
// to be saved then no space is actually allocated and this pointer is
// not used.
//
// XT_CP_ASA
// Pointer to aligned save area for coprocessor state. This is filled in
// only if coprocessor state is to be saved for the thread. Allows it to be
// aligned more than the overall save area (which might be stack-aligned
// or TCB-aligned). Especially relevant for Xtensa cores configured with a

/*
One thing I noticed is different between my initial idea of stack
assignments to RTC threads, when comparing to interrupts, is that I
expected each RTC thread priority to have its own stack, whereas
interrupts of different priorities share an interrupt stack.
It's not really a difference in memory usage, because when assigning
multiple priorities to a stack, you have to add-up worst-case for
all priorities. One possible functional difference is that with
separate stacks per priority, it's possible to dynamically change
the priority of an RTC thread (while it's running). Not sure how
valuable that might be -- changing priority is useful with priority
inheritance, to avoid priority inversion, but I don't know how often
an RTC thread might acquire a lock (it couldn't block on acquiring a
lock in the usual sense -- it could get queued waiting and be restarted
when it becomes available, or use try_lock instead of lock).

* to use for multiple processor configurations (eg. the Flash might contain
* the Ethernet card's address, endianness-independent application data, etc).
* That is, byte sequences written in Flash by a core of a given endianness
* will be byte-swapped when seen by a core of the other endianness.

lcd-splc780d-board.h Board-specific LCD info on Avnet AV60 (XT-AV60) board.
Interface between board-independent driver and board-specific header.
This is used by a board-independent SPLC780D LCD controller driver to obtain
board-specific information about LCD displays on the board, such as the
controller register base address and spacing (a function of how the address
lines are connected on the board) and length of the visible window of the
display (a function of the LCD panel the controller drives). The driver does
not refer directly to the board-specific header, which therefore is not
constrained to use macro names consistent with other boards.
!! Must not contain any board-specific macro names (only controller specific) !!
Included at compile-time via an include path specific to the board.
The XT-AV60 board contains a single MYTech MOC-16216B-B display driven by
a Sunplus SPLC870D controller.

xtbsp.h Xtensa Board Support Package API
This API defines a minimal set of board-support functions that every supported
Xtensa board is expected to provide in the board-support-package (BSP) library
associated with the board-specific LSP. Only basic board functions are provided
in this board-independent API. API functions not applicable to a board must be
stubbed in its BSP library. More complex operations must use a board-specific
interface. Functions are grouped by type of peripheral device.
