| 19 | /* An architecture-specific version of this file has to defined a | ||
| 20 | number of symbols: | ||
| 21 | |||
| 22 | TLS_TCB_AT_TP or TLS_DTV_AT_TP | ||
| 23 | |||
| 24 | The presence of one of these symbols signals which variant of | ||
| 25 | the TLS ABI is used. There are in the moment two variants | ||
| 26 | available: | ||
| 27 | |||
| 28 | * the thread pointer points to a thread control block | ||
| 29 | |||
| 30 | * the thread pointer points to the dynamic thread vector | ||
| 31 | |||
| 32 | |||
| 33 | TLS_TCB_SIZE | ||
| 34 | |||
| 35 | This is the size of the thread control block structure. How | ||
| 36 | this is actually defined depends on the ABI. The thread control | ||
| 37 | block could be internal descriptor of the thread library or | ||
| 38 | just a data structure which allows finding the DTV. | ||
| 39 | |||
| 40 | TLS_INIT_TCB_SIZE | ||
| 41 | |||
| 42 | Similarly, but this value is only used at startup and in the | ||
| 43 | dynamic linker itself. There are no threads in use at that time. | ||
| 44 | |||
| 45 | |||
| 46 | TLS_TCB_ALIGN | ||
| 47 | |||
| 48 | Alignment requirements for the TCB structure. | ||
| 49 | |||
| 50 | TLS_INIT_TCB_ALIGN | ||
| 51 | |||
| 52 | Similarly, but for the structure used at startup time. | ||
| 53 | |||
| 54 | |||
| 55 | INSTALL_DTV(tcb, init_dtv) | ||
| 56 | |||
| 57 | This macro must install the given initial DTV into the thread control | ||
| 58 | block TCB. The normal runtime functionality must then be able to | ||
| 59 | use the value. | ||
| 60 | |||
| 61 | |||
| 62 | TLS_INIT_TP(tcb) | ||
| 63 | |||
| 64 | This macro must initialize the thread pointer to enable normal TLS | ||
| 65 | operation. The parameter is a pointer to the thread control block. | ||
| 66 | ld.so calls this macro once. | ||
| 67 | |||
| 68 | |||
| 69 | THREAD_DTV() | ||
| 70 | |||
| 71 | This macro returns the address of the DTV of the current thread. | ||
| 72 | This normally is done using the thread register which points | ||
| 73 | to the dtv or the TCB (from which the DTV can found). | ||
| 74 | |||
| 75 | |||
| 76 | THREAD_GSCOPE_IN_TCB | ||
| 77 | |||
| 78 | This should be set to 1 if the global scope flag is stored within the TCB. | ||
| 79 | When set to 0, GL(_dl_thread_gscope_count) will be defined to store it. | ||

| 30 | for changes to the lock state, | ||
| 31 | >1: acquired, possibly with waiters; there may be other threads blocked or | ||
| 32 | about to block for changes to the lock state. | ||
| 33 | |||
| 34 | We expect that the common case is an uncontended lock, so we just need | ||
| 35 | to transition the lock between states 0 and 1; releasing the lock does | ||
| 36 | not need to wake any other blocked threads. If the lock is contended | ||
| 37 | and a thread decides to block using a futex operation, then this thread | ||
| 38 | needs to first change the state to >1; if this state is observed during | ||
| 39 | lock release, the releasing thread will wake one of the potentially | ||
| 40 | blocked threads. | ||
| 41 | |||
| 42 | Much of this code takes a 'private' parameter. This may be: | ||
| 43 | LLL_PRIVATE: lock only shared within a process | ||
| 44 | LLL_SHARED: lock may be shared across processes. | ||
| 45 | |||
| 46 | Condition variables contain an optimization for broadcasts that requeues | ||
| 47 | waiting threads on a lock's futex. Therefore, there is a special | ||
| 48 | variant of the locks (whose name contains "cond") that makes sure to | ||
| 49 | always set the lock state to >1 and not just 1. | ||
| 50 | |||
| 51 | Robust locks set the lock to the id of the owner. This allows detection | ||
| 52 | of the case where the owner exits without releasing the lock. Flags are | ||
| 53 | OR'd with the owner id to record additional information about lock state. | ||
| 54 | Therefore the states of robust locks are: | ||
| 55 | 0: not acquired | ||
| 56 | id: acquired (by user identified by id & FUTEX_TID_MASK) | ||
| 57 | |||
| 58 | The following flags may be set in the robust lock value: | ||
| 59 | FUTEX_WAITERS - possibly has waiters | ||
| 60 | FUTEX_OWNER_DIED - owning user has exited without releasing the futex. */ | ||

| 141 | 20(%esp) Arg# 5 | ||
| 142 | 16(%esp) Arg# 4 | ||

| 144 | 8(%esp) Arg# 2 | ||
| 145 | 4(%esp) Arg# 1 | ||
| 146 | (%esp) Return address | ||
| 147 | |||
| 148 | (Of course a function with say 3 arguments does not have entries for | ||
| 149 | arguments 4, 5, and 6.) | ||
| 150 | |||
| 151 | The following code tries hard to be optimal. A general assumption | ||
| 152 | (which is true according to the data books I have) is that | ||
| 153 | |||
| 154 | 2 * xchg is more expensive than pushl + movl + popl | ||
| 155 | |||
| 156 | Beside this a neat trick is used. The calling conventions for Linux | ||
| 157 | tell that among the registers used for parameters %ecx and %edx need | ||
| 158 | not be saved. Beside this we may clobber this registers even when | ||
| 159 | they are not used for parameter passing. | ||
| 160 | |||
| 161 | As a result one can see below that we save the content of the %ebx | ||
| 162 | register in the %edx register when we have less than 3 arguments | ||
| 163 | (2 * movl is less expensive than pushl + popl). | ||
| 164 | |||
| 165 | Second unlike for the other registers we don't save the content of | ||
| 166 | %ecx and %edx when we have more than 1 and 2 registers resp. | ||
| 167 | |||
| 168 | The code below might look a bit long but we have to take care for | ||
| 169 | the pipelined processors (i586). Here the `pushl' and `popl' | ||
| 170 | instructions are marked as NP (not pairable) but the exception is | ||
| 171 | two consecutive of these instruction. This gives no penalty on | ||
| 172 | other processors though. */ | ||

| 77 | clobbered by the syscall interrupted, and needed to be reinititalized. | ||
| 78 | The kernel would decrement the PC by 4 before switching back to the | ||
| 79 | user mode so that $v0 had been reloaded before SYSCALL was executed | ||
| 80 | again. This implied the place $v0 was loaded from must have been | ||
| 81 | preserved across a syscall, e.g. an immediate, static register, stack | ||
| 82 | slot, etc. | ||

| 86 | first appeared in the 2.6.36 release. Since then the kernel has had | ||
| 87 | code that reloads $v0 upon syscall restart and resumes right at the | ||
| 88 | SYSCALL instruction, so no special arrangement is needed anymore. | ||
| 89 | |||
| 90 | For backwards compatibility with existing kernel binaries we support | ||

| 80 | The kernel would decrement the PC by 4 before switching back to the | ||
| 81 | user mode so that $v0 had been reloaded before SYSCALL was executed | ||

| 89 | code that reloads $v0 upon syscall restart and resumes right at the | ||
| 90 | SYSCALL instruction, so no special arrangement is needed anymore. | ||
| 91 | |||
| 92 | For backwards compatibility with existing kernel binaries we support | ||
| 93 | the old convention by choosing the instruction preceding SYSCALL | ||
| 94 | carefully. This also means we have to force a 32-bit encoding of the | ||

| 74 | syscall number. Then if a restart triggered, $v0 would have been | ||
| 75 | clobbered by the syscall interrupted, and needed to be reinititalized. | ||
| 76 | The kernel would decrement the PC by 4 before switching back to the | ||
| 77 | user mode so that $v0 had been reloaded before SYSCALL was executed | ||
| 78 | again. This implied the place $v0 was loaded from must have been | ||
| 79 | preserved across a syscall, e.g. an immediate, static register, stack | ||
| 80 | slot, etc. | ||
| 81 | |||
| 82 | The convention was relaxed in Linux with a change applied to the kernel | ||
| 83 | GIT repository as commit 96187fb0bc30cd7919759d371d810e928048249d, that | ||
| 84 | first appeared in the 2.6.36 release. Since then the kernel has had | ||
| 85 | code that reloads $v0 upon syscall restart and resumes right at the | ||
| 86 | SYSCALL instruction, so no special arrangement is needed anymore. | ||
| 87 | |||
| 88 | For backwards compatibility with existing kernel binaries we support | ||
| 89 | the old convention by choosing the instruction preceding SYSCALL | ||
| 90 | carefully. This also means we have to force a 32-bit encoding of the | ||
