+ * Syscall argument mungers.
+ *
+ * The data to be munged has been explicitly copied in to the arguement area,
+ * and will be munged in place in the uu_arg[] array. Because of this, the
+ * functions all take the same arguments as their PPC equivalents, but the
+ * first argument is ignored. These mungers are for 32-bit app's syscalls,
+ * since 64-bit args are stored into the save area (which overlays the
+ * uu_args) in the order the syscall ABI calls for.
+ *
+ * The issue is that the incoming args are 32-bit, but we must expand
+ * them in place into 64-bit args, as if they were from a 64-bit process.
+ *
+ * There are several functions in this file. Each takes two parameters:
+ *
+ * void munge_XXXX( const void *regs, void *uu_args);
+ *
+ * The name of the function encodes the number and type of the parameters,
+ * as follows:
+ *
+ * w = a 32-bit value such as an int or a 32-bit ptr, that does not
+ * require sign extension. These are handled by zeroing a word
+ * of output, and copying a word from input to output.
+ *
+ * s = a 32-bit value such as a long, which must be sign-extended to
+ * a 64-bit long-long in the uu_args. These are handled by
+ * loading a word of input and sign extending it to a double,
+ * and storing two words of output.
+ *
+ * l = a 64-bit long-long. These are handled by copying two words
+ * of input to the output.
+ *
+ * For example, "munge_wls" takes a word, a long-long, and a word. This
+ * takes four words in the uu_arg[] area: the first word is in one, the
+ * long-long takes two, and the final word is in the fourth. We store six
+ * words: the low word is left in place, followed by a 0, followed by the
+ * two words of the long-long, followed by the low word and the sign extended
+ * high word of the preceeding low word.
+ *
+ * Because this is an in-place modification, we actually start at the end
+ * of uu_arg[] and work our way back to the beginning of the array.
+ *
+ * As you can see, we save a lot of code by collapsing mungers that are
+ * prefixes or suffixes of each other.

+.Sh NAME
+.Nm i386_get_ldt ,
+.Nm i386_set_ldt
+.Nd manage i386 per-process Local Descriptor Table entries
+.Sh LIBRARY
+.Lb libc
+.Sh SYNOPSIS
+.In architecture/i386/table.h
+.In i386/user_ldt.h
+.Ft int
+.Fn i386_get_ldt "int start_sel" "union ldt_entry *descs" "int num_sels"
+.Ft int
+.Fn i386_set_ldt "int start_sel" "union ldt_entry *descs" "int num_sels"
+.Sh DESCRIPTION
+The
+.Fn i386_get_ldt
+system call
+will return the list of i386 descriptors that the process has in its
+LDT.
+The
+.Fn i386_set_ldt
+system call
+will set a list of i386 descriptors for the current process in its
+LDT.
+Both routines accept a starting selector number
+.Fa start_sel ,
+an array of memory that
+will contain the descriptors to be set or returned
+.Fa descs ,
+and the number of entries to set or return
+.Fa num_sels .
+.Pp
+The argument
+.Fa descs
+can be either code_desc_t, data_desc_t or call_gate_t and are defined in
+.In architecture/i386/desc.h .
+These structures are defined by the architecture
+as disjoint bit-fields, so care must be taken in constructing them.
+.Pp
+If
+.Fa start_sel
+is
+.Em LDT_AUTO_ALLOC ,
+.Fa num_sels
+is 1 and the descriptor pointed to by
+.Fa descs
+is legal, then
+.Fn i386_set_ldt
+will allocate a descriptor and return its
+selector number.
+.Pp
+If
+.Fa num_descs
+is 1,
+.Fa start_sels
+is valid, and
+.Fa descs
+is NULL, then
+.Fn i386_set_ldt
+will free that descriptor
+(making it available to be reallocated again later).
+.Pp
+If
+.Fa num_descs
+is 0,
+.Fa start_sels
+is 0 and
+.Fa descs
+is NULL then, as a special case,
+.Fn i386_set_ldt
+will free all descriptors.
+.Sh RETURN VALUES
+Upon successful completion,
+.Fn i386_get_ldt
+returns the number of descriptors currently in the LDT.
+The
+.Fn i386_set_ldt
+system call
+returns the first selector set.
+In the case when a descriptor is allocated by the kernel, its number will
+be returned.
+Otherwise, a value of -1 is returned and the global
+variable
+.Va errno
+is set to indicate the error.
+.Sh ERRORS
+The
+.Fn i386_get_ldt
+and
+.Fn i386_set_ldt
+system calls
+will fail if:
+.Bl -tag -width Er
+.It Bq Er EINVAL
+An inappropriate value was used for
+.Fa start_sel
+or
+.Fa num_sels .
+.It Bq Er EACCES
+The caller attempted to use a descriptor that would
+circumvent protection or cause a failure.

+ @class IODMACommand
+ @abstract A mechanism to convert memory references to I/O bus addresses.
+ @discussion The IODMACommand is supersedes the IOMemoryCursor and greatly enhances the functionality and power of it. The command can be specified to output 64 bit physical addresses and also allows driver writers bypass mapping hardware or get addresses suitable for non-snooped DMA.
+<br><br>
+ The command is designed to be very easily subclassable. Most driver writers need to associate some DMA operations with their memory descriptor and usually use a C structure for that purpose. This structure is often kept in a linked list. This IODMACommand has built it <kern/queue.h> linkage and can be derived and 'public:' variables added, giving the developer a structure that can associate a memory descriptor with a particular dma command but will also allow the developer to generate that command and keep the state necessary for tracking it.
+<br><br>
+ It is envisaged that a pool of IODMACommands will be created at driver initialisation and each command will be kept in an IOCommandPool while not in use. However if developers wishes to maintain their own free lists that is certainly possible. See the <kern/queue.h> and <xnu/iokit/Kernel/IOCommandPool> for sample code on manipulating the command's doubly linked list entries.
+<br><br>
+ The IODMACommand can be used in a 'weak-linked' manner. To do this you must avoid using any static member functions. Use the, much slower but safe, weakWithSpecification function. On success a dma command instance will be returned. This instance can then be used to clone as many commands as is needed. Remember deriving from this class can not be done weakly, that is no weak subclassing!

+ *
+ * First, the polynomial itself and its table of feedback terms. The
+ * polynomial is
+ * X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0
+ *
+ * Note that we take it "backwards" and put the highest-order term in
+ * the lowest-order bit. The X^32 term is "implied"; the LSB is the
+ * X^31 term, etc. The X^0 term (usually shown as "+1") results in
+ * the MSB being 1
+ *
+ * Note that the usual hardware shift register implementation, which
+ * is what we're using (we're merely optimizing it by doing eight-bit
+ * chunks at a time) shifts bits into the lowest-order term. In our
+ * implementation, that means shifting towards the right. Why do we
+ * do it this way? Because the calculated CRC must be transmitted in
+ * order from highest-order term to lowest-order term. UARTs transmit
+ * characters in order from LSB to MSB. By storing the CRC this way
+ * we hand it to the UART in the order low-byte to high-byte; the UART
+ * sends each low-bit to hight-bit; and the result is transmission bit
+ * by bit from highest- to lowest-order term without requiring any bit
+ * shuffling on our part. Reception works similarly
+ *
+ * The feedback terms table consists of 256, 32-bit entries. Notes
+ *
+ * The table can be generated at runtime if desired; code to do so
+ * is shown later. It might not be obvious, but the feedback
+ * terms simply represent the results of eight shift/xor opera
+ * tions for all combinations of data and CRC register values
+ *
+ * The values must be right-shifted by eight bits by the "updcrc
+ * logic; the shift must be unsigned (bring in zeroes). On some
+ * hardware you could probably optimize the shift in assembler by
+ * using byte-swap instructions
+ * polynomial $edb88320

* Here's what to do if you want to add a new routine to the comm page:
*
- * 1. Add a definition for it's address in osfmk/ppc/cpu_capabilities.h,
+ * 1. Add a definition for it's address in osfmk/i386/cpu_capabilities.h,
* being careful to reserve room for future expansion.
*
* 2. Write one or more versions of the routine, each with it's own
* commpage_descriptor. The tricky part is getting the "special",
* "musthave", and "canthave" fields right, so that exactly one
* version of the routine is selected for every machine.
- * The source files should be in osfmk/ppc/commpage/.
+ * The source files should be in osfmk/i386/commpage/.

+ * the copy engine has the following characteristics
+ * - copyio handles copies to/from user or kernel space
+ * - copypv deals with physical or virtual addresses
+ *
+ * implementation details as follows
+ * - a cache of up to NCOPY_WINDOWS is maintained per thread for
+ * access of user virutal space
+ * - the window size is determined by the amount of virtual space
+ * that can be mapped by a single page table
+ * - the mapping is done by copying the page table pointer from
+ * the user's directory entry corresponding to the window's
+ * address in user space to the directory entry corresponding
+ * to the window slot in the kernel's address space
+ * - the set of mappings is preserved across context switches,
+ * so the copy can run with pre-emption enabled
+ * - there is a gdt entry set up to anchor the kernel window on
+ * each processor
+ * - the copies are done using the selector corresponding to the
+ * gdt entry
+ * - the addresses corresponding to the user virtual address are
+ * relative to the beginning of the window being used to map
+ * that region... thus the thread can be pre-empted and switched
+ * to a different processor while in the midst of a copy
+ * - the window caches must be invalidated if the pmap changes out
+ * from under the thread... this can happen during vfork/exec...
+ * inval_copy_windows is the invalidation routine to be used
+ * - the copyio engine has 4 different states associated with it
+ * that allows for lazy tlb flushes and the ability to avoid
+ * a flush all together if we've just come from user space
+ * the 4 states are as follows...
+ *
+ * WINDOWS_OPENED - set by copyio to indicate to the context
+ * switch code that it is necessary to do a tlbflush after
+ * switching the windows since we're in the middle of a copy
+ *
+ * WINDOWS_CLOSED - set by copyio to indicate that it's done
+ * using the windows, so that the context switch code need
+ * not do the tlbflush... instead it will set the state to...
+ *
+ * WINDOWS_DIRTY - set by the context switch code to indicate
+ * to the copy engine that it is responsible for doing a
+ * tlbflush before using the windows again... it's also
+ * set by the inval_copy_windows routine to indicate the
+ * same responsibility.
+ *
+ * WINDOWS_CLEAN - set by the return to user path to indicate
+ * that a tlbflush has happened and that there is no need
+ * for copyio to do another when it is entered next...
+ *
+ * - a window for mapping single physical pages is provided for copypv
+ * - this window is maintained across context switches and has the
+ * same characteristics as the user space windows w/r to pre-emption

-/*
-* TLB Coherence Code (TLB "shootdown" code)
-*
-* Threads that belong to the same task share the same address space and
-* hence share a pmap. However, they may run on distinct cpus and thus
-* have distinct TLBs that cache page table entries. In order to guarantee
-* the TLBs are consistent, whenever a pmap is changed, all threads that
-* are active in that pmap must have their TLB updated. To keep track of
-* this information, the set of cpus that are currently using a pmap is
-* maintained within each pmap structure (cpus_using). Pmap_activate() and
-* pmap_deactivate add and remove, respectively, a cpu from this set.
-* Since the TLBs are not addressable over the bus, each processor must
-* flush its own TLB; a processor that needs to invalidate another TLB
-* needs to interrupt the processor that owns that TLB to signal the
-* update.
-*
-* Whenever a pmap is updated, the lock on that pmap is locked, and all
-* cpus using the pmap are signaled to invalidate. All threads that need
-* to activate a pmap must wait for the lock to clear to await any updates
-* in progress before using the pmap. They must ACQUIRE the lock to add
-* their cpu to the cpus_using set. An implicit assumption made
-* throughout the TLB code is that all kernel code that runs at or higher
-* than splvm blocks out update interrupts, and that such code does not
-* touch pageable pages.
-*
-* A shootdown interrupt serves another function besides signaling a
-* processor to invalidate. The interrupt routine (pmap_update_interrupt)
-* waits for the both the pmap lock (and the kernel pmap lock) to clear,
-* preventing user code from making implicit pmap updates while the
-* sending processor is performing its update. (This could happen via a
-* user data write reference that turns on the modify bit in the page
-* table). It must wait for any kernel updates that may have started
-* concurrently with a user pmap update because the IPC code
-* changes mappings.
-* Spinning on the VALUES of the locks is sufficient (rather than
-* having to acquire the locks) because any updates that occur subsequent
-* to finding the lock unlocked will be signaled via another interrupt.
-* (This assumes the interrupt is cleared before the low level interrupt code
-* calls pmap_update_interrupt()).
-*
-* The signaling processor must wait for any implicit updates in progress
-* to terminate before continuing with its update. Thus it must wait for an
-* acknowledgement of the interrupt from each processor for which such
-* references could be made. For maintaining this information, a set
-* cpus_active is used. A cpu is in this set if and only if it can
-* use a pmap. When pmap_update_interrupt() is entered, a cpu is removed from
-* this set; when all such cpus are removed, it is safe to update.
-*
-* Before attempting to acquire the update lock on a pmap, a cpu (A) must
-* be at least at the priority of the interprocessor interrupt
-* (splip<=splvm). Otherwise, A could grab a lock and be interrupted by a
-* kernel update; it would spin forever in pmap_update_interrupt() trying
-* to acquire the user pmap lock it had already acquired. Furthermore A
-* must remove itself from cpus_active. Otherwise, another cpu holding
-* the lock (B) could be in the process of sending an update signal to A,
-* and thus be waiting for A to remove itself from cpus_active. If A is
-* spinning on the lock at priority this will never happen and a deadlock
-* will result.

- * Basically, it is a register that counts at a fixed rate and can be
- * programmed to generate an interrupt every N counts. The count rate is
- * clknum counts per sec (see pit.h), historically 1193167=14.318MHz/12
- * but the more accurate value is 1193182=14.31818MHz/12. [14.31818 MHz being
- * the master crystal oscillator reference frequency since the very first PC.]
- * Various constants are computed based on this value, and we calculate
- * them at init time for execution efficiency. To obtain sufficient
- * accuracy, some of the calculation are most easily done in floating
- * point and then converted to int.
+ * tsc_to_nanoseconds:

- *
- * The theory here is that we know how many TSCs-per-sec the processor runs at.
- * Normally to convert this to nanoseconds you would multiply the current

- * Instead, we create this quant constant and it becomes the numerator,

- * user space as the numer and pass 0xFFFFFFFF (RTC_FAST_DENOM) as the denom to
- * convert raw counts * to nanos. The difference is so small as to be

* Nanotime/mach_absolutime_time
* -----------------------------
- * The timestamp counter (tsc) - which counts cpu clock cycles and can be read
- * efficient by the kernel and in userspace - is the reference for all timing.
- * However, the cpu clock rate is not only platform-dependent but can change
- * (speed-step) dynamically. Hence tsc is converted into nanoseconds which is
- * identical to mach_absolute_time. The conversion to tsc to nanoseconds is
- * encapsulated by nanotime.
+ * The timestamp counter (TSC) - which counts cpu clock cycles and can be read
+ * efficiently by the kernel and in userspace - is the reference for all timing.
+ * The cpu clock rate is platform-dependent and may stop or be reset when the
+ * processor is napped/slept. As a result, nanotime is the software abstraction
+ * used to maintain a monotonic clock, adjusted from an outside reference as needed.
*
* The kernel maintains nanotime information recording:
- * - the current ratio of tsc to nanoseconds
+ * - the ratio of tsc to nanoseconds
* with this ratio expressed as a 32-bit scale and shift
* (power of 2 divider);
- * - the tsc (step_tsc) and nanotime (step_ns) at which the current
- * ratio (clock speed) began.
- * So a tsc value can be converted to nanotime by:
+ * - { tsc_base, ns_base } pair of corresponding timestamps.
*
- * nanotime = (((tsc - step_tsc)*scale) >> shift) + step_ns
+ * The tuple {tsc_base, ns_base, scale, shift} is exported in the commpage
+ * for the userspace nanotime routine to read.
*
- * In general, (tsc - step_tsc) is a 64-bit quantity with the scaling
- * involving a 96-bit intermediate value. However, by saving the converted
- * values at each tick (or at any intervening speed-step) - base_tsc and
- * base_ns - we can perform conversions relative to these and be assured that
- * (tsc - tick_tsc) is 32-bits. Hence:
- *
- * fast_nanotime = (((tsc - base_tsc)*scale) >> shift) + base_ns
- *
- * The tuple {base_tsc, base_ns, scale, shift} is exported in the commpage
- * for the userspace nanotime routine to read. A duplicate check_tsc is
- * appended so that the consistency of the read can be verified. Note that
- * this scheme is essential for MP systems in which the commpage is updated
- * by the master cpu but may be read concurrently by other cpus.
- *
+ * All of the routines which update the nanotime data are non-reentrant. This must
+ * be guaranteed by the caller.

+ * getting the encrypted data from its backing VM object, itself backed by
