The value of the _r_e_q_u_e_s_t parameter determines the meaning of the remaining arguments. In the descriptions below, _a_r_g_1, _a_r_g_2, and _a_r_g_3 refer to parameters following the _r_e_q_u_e_s_t argument. The following requests are currently supported: SSSSGGGGIIII____SSSSYYYYSSSSIIIIDDDD Returns an identifier for the given system. This identifier is guaranteed to be unique within the Silicon Graphics product family. The argument _a_r_g_1 for this _r_e_q_u_e_s_t should be a pointer to a character buffer of MMMMAAAAXXXXSSSSYYYYSSSSIIIIDDDDSSSSIIIIZZZZEEEE characters. SSSSGGGGIIII____RRRRDDDDNNNNAAAAMMMMEEEE Returns the process name for the process id specified in _a_r_g_1. The arguments _a_r_g_2 and _a_r_g_3 give the address and length, respectively, of the buffer which will receive the name string. This name corresponds to the name in the _CCCC_OOOO_MMMM_MMMM_AAAA_NNNN_DDDD column of _p_s(1) for the given process. The returned string will be null-terminated unless the caller's buffer is too small, in which case the string is simply truncated at the size of the buffer. The return value gives the number of bytes copied to the buffer, which will be the minimum of the size of the buffer and the size of the field in the user structure that contains the process name. Note that this means that the returned length will typically be greater than the actual length of the name string (in the sense of _s_t_r_l_e_n(3)). SSSSGGGGIIII____RRRRDDDDUUUUBBBBLLLLKKKK Was an obsolete feature and has been discontinued. Users are directed to the process filesystem (see _p_r_o_c(4).) to obtain information about a process.

SSSSGGGGIIII____TTTTUUUUNNNNEEEE This request allows the superuser to redefine tunable variables to more accurately reflect system use. The argument _a_r_g_1 is a buffer pointer which specifies a group name of the tunable variable. The argument _a_r_g_2 is a buffer pointer which holds the address of the tunable variable. _a_r_g_3 should be a buffer containing the tune value. _s_y_s_t_u_n_e(1M) is the preferred way to change these variables. This system call is only supported for 64 bit programs when running on 64 bit kernels. PPPPaaaaggggeeee 1111 ssssyyyyssssssssggggiiii((((2222)))) ssssyyyyssssssssggggiiii((((2222)))) SSSSGGGGIIII____IIIIDDDDBBBBGGGG Used internally for kernel debugging. SSSSGGGGIIII____IIIINNNNVVVVEEEENNNNTTTT Returns information about the hardware inventory of the system.

If _a_r_g_1 is SSSSGGGGIIII____IIIINNNNVVVV____RRRREEEEAAAADDDD then _a_r_g_3 bytes worth of inventory records are read into the buffer specified by _a_r_g_2. Applications should use _g_e_t_i_n_v_e_n_t(3) to access this information; this internal interface may change. SSSSGGGGIIII____SSSSEEEETTTTLLLLEEEEDDDD If _a_r_g_1 is 1, turn on an LED on the machine. 0 turns it off. This is only available on some SGI computers. SSSSGGGGIIII____SSSSEEEETTTTNNNNVVVVRRRRAAAAMMMM Sets nvram variable with given value. Nvram variables are subset of IRIS PROM Monitor environment variables, which are saved in EEPROM, and the values of which are preserved over power cycle. _a_r_g_1 is a buffer pointer which specifies a name of nvram variable. _a_r_g_2 is a buffer pointer which holds the value of the nvram variable. Both buffers pointed by _a_r_g_1 and _a_r_g_2 must be at least 128 bytes long. SSSSGGGGIIII____GGGGEEEETTTTNNNNVVVVRRRRAAAAMMMM Retrieve values of the IRIS PROM Monitor environment variables. (see _s_g_i_k_o_p_t(2)). _a_r_g_1 is a buffer pointer which specifies either name or index of a IRIS PROM Monitor variable. Both name and index must be ASCII string. _a_r_g_2 is a buffer pointer in which the value be returned. Both buffers pointed by _a_r_g_1 and _a_r_g_2 should be at least 128 bytes long.

SSSSGGGGIIII____RRRREEEEAAAADDDDBBBB SSSSGGGGIIII____WWWWRRRRIIIITTTTEEEEBBBB These are used to read and write character special devices that are greater than 2Gb. _a_r_g_1 is the file descriptor pointing to a character special device. _a_r_g_2 is a buffer in the user's space where the data will be transferred from or to. _a_r_g_3 is the block (512 bytes) offset of where to start the transaction. _a_r_g_4 is the number of blocks to transfer. This interface is superseded in IRIX Release 5.3 by the use of _l_s_e_e_k_6_4, which provides 64-bit seek offsets. SSSSGGGGIIII____SSSSSSSSYYYYNNNNCCCC Synchronously flush out all delayed write buffers. PPPPaaaaggggeeee 3333 ssssyyyyssssssssggggiiii((((2222)))) ssssyyyyssssssssggggiiii((((2222)))) SSSSGGGGIIII____BBBBDDDDFFFFLLLLUUUUSSSSHHHHCCCCNNNNTTTT Allows the calling process to delay the kernel from writing out delayed write buffers by _a_r_g_1 seconds. After that, the normal flush delay will apply. At the end of the system call, the kernel will return the old flush delay. This system call is intended to be used in conjunction with the SSSSGGGGIIII____SSSSSSSSYYYYNNNNCCCC system call on a single processor machine to provide the calling process with an environment that is free of any unwanted disk activities for the period of _a_r_g_1 seconds. SSSSGGGGIIII____QQQQUUUUEEEERRRRYYYY____FFFFTTTTIIIIMMMMEEEERRRR Used by _f_t_i_m_e_r(1). SSSSGGGGIIII____CCCCYYYYCCCCLLLLEEEECCCCNNNNTTTTRRRR____SSSSIIIIZZZZEEEE Returns the size of the integer needed to read the cycle counter. This is useful along with SGI_QUERY_CYCLECNTR to write machine independent code to read the free running hardware counter. On some machines the value needs to be read into a 32 bit integer, and on others the cycle counter needs to be read into a 64 bit integer. SSSSGGGGIIII____QQQQUUUUEEEERRRRYYYY____CCCCYYYYCCCCLLLLEEEECCCCNNNNTTTTRRRR It is best to use the clock_gettime(2) interface with the CLOCK_SGI_CYCLE clock instead of mapping the counter yourself. This is a much more portable solution. That said, this syssgi option returns information about the free running hardware counter on systems that support a high resolution timer. Upon successful completion, an address for the counter is returned. The size of the integer needed to hold the count can be found using the SGI_CYCLECNTR_SIZE syssgi call. On machines with 64-bit counters it can either be read with two separate 32-bit accesses (one at the returned address, and the other at the returned address plus four), or with a single 64-bit "long long" access in MIPS3 or MIPS4 applications. The address must be mapped read-only into the user process space via the _m_m_a_p(2) system call into ////ddddeeeevvvv////mmmmmmmmeeeemmmm before any access can be made. Not all systems return page aligned addresses, so the address must be masked to be page aligned, and the offset added back to the returned mmap address, in order for code to work on all systems, so typically you would see code like this (ignoring error checking): #include <stddef.h> #include <sys/types.h> #include <fcntl.h> #include <sys/mman.h> #include <sys/syssgi.h> PPPPaaaaggggeeee 4444 ssssyyyyssssssssggggiiii((((2222)))) ssssyyyyssssssssggggiiii((((2222)))) #if CYCLE_COUNTER_IS_64BIT typedef unsigned long long iotimer_t; #else typedef unsigned int iotimer_t; #endif __psunsigned_t phys_addr, raddr; unsigned int cycleval; volatile iotimer_t counter_value, *iotimer_addr; int fd, poffmask; poffmask = getpagesize() - 1; phys_addr = syssgi(SGI_QUERY_CYCLECNTR, &cycleval); raddr = phys_addr & ~poffmask; fd = open("/dev/mmem", O_RDONLY); iotimer_addr = (volatile iotimer_t *)mmap(0, poffmask, PROT_READ, MAP_PRIVATE, fd, (off_t)raddr); iotimer_addr = (iotimer_t *)((__psunsigned_t)iotimer_addr + (phys_addr & poffmask)); counter_value = *iotimer_addr; For the Challenge/ONYX and OCTANE families 64-bit counter, define CYCLE_COUNTER_IS_64BIT. Sixty-four bit (MIPS 3, MIPS 4) applications may simply use the example above with CYCLE_COUNTER_IS_64BIT defined. Thirty-two bit applications need to read the halves separately and check for wrap-around. Pass iotimer_addr and two unsigned int pointers to the following routine: void read_time(volatile unsigned *iotimer_addr, unsigned *high, unsigned *low) { while (1) { *high = *iotimer_addr; *low = *(iotimer_addr + 1); if (*high == *iotimer_addr) { return; } } } This will put the top and bottom 32 bits of the time into the memory pointed to by high and low, respectively. If you only need 32-bit precision, you may use the original example but replace the counter_value assignment with counter_value = *(iotimer_addr + 1); SSSSGGGGIIII____SSSSEEEETTTTTTTTIIIIMMMMEEEETTTTRRRRIIIIMMMM changes the value of timetrim from the initial value configured in ////vvvvaaaarrrr////ssssyyyyssssggggeeeennnn////mmmmttttuuuunnnneeee////kkkkeeeerrrrnnnneeeellll (see _l_b_o_o_t(1M) and _a_d_j_t_i_m_e(2)).

SSSSGGGGIIII____GGGGEEEETTTTTTTTIIIIMMMMEEEETTTTRRRRIIIIMMMM obtains the current value of timetrim. The argument _a_r_g_1 must be a pointer to an integer, into which the timetrim value is stored. SSSSGGGGIIII____SSSSEEEETTTT____AAAAUUUUTTTTOOOOPPPPWWWWRRRROOOONNNN Is used to set the time at which the system will automatically power on (if it is powered off at that time). If the system is not powered off at that time (hasn't yet been shutdown and powered off), the call has no effect. Rebooting the system clears the value. This is currently implemented only on OCTANE, Indy, Indigo and Challenge M systems. The 3rd argument is a time_t whose value is the time in seconds from 1 Jan 1970 midnight GMT at which to turn the system on. Also see the _w_a_k_e_u_p_a_t(1M) man page. See the ENOPKG description below for systems not implementing this function.

SSSSGGGGIIII____SSSSEEEETTTT____FFFFPPPP____PPPPRRRREEEECCCCIIIISSSSEEEE Modifies floating point exception mode for the current process. This is only meaningful on processors that support multiple modes. On these processors, the default mode is usually performance mode (also called imprecise exception mode) and non-sequential memory (nsmm) mode. On all other processors, the default is precise exception and sequential (smm) mode. _a_r_g_1 should be non-zero in order to enable precise exception mode. A value of zero will disable precise exception mode thereby enabling performance mode. PPPPaaaaggggeeee 6666 ssssyyyyssssssssggggiiii((((2222)))) ssssyyyyssssssssggggiiii((((2222)))) In precise exception mode, all floating point exceptions/interrupts are reported on the instruction that caused the exception, so floating point signal handlers can clean up the FP state and continue execution. In performance mode, floating point interrupts are asynchronous and the reported program counter is meaningless. Precise mode is provided as a means of debugging processes and/or backward compatibility for programs that have knowledge of the FP state. It causes significant performance degradation. Currently this call only has an affect on machines with an R8000 processor since that is the only processor which supports this dual execution mode. SSSSGGGGIIII____GGGGEEEETTTT____FFFFPPPP____PPPPRRRREEEECCCCIIIISSSSEEEE Returns the floating point exception mode for the current process.

The bitmask is 64 bits long, and the least significant bit corresponds to inode _xxxx_iiii______ssss_tttt_aaaa_rrrr_tttt_iiii_nnnn_oooo. Each bit is set if the corresponding inode is in use. _a_r_g_5 is a pointer to a count of returned values, filled in by the call.
