* o Fix handling of interrupted syscalls.Ralf Baechle1998-03-2213-110/+100
| | | | | | | | | | | | o Just count missed heartbeats on Indys but don't print a messages. This was a bug by itself. o Fix a crash in exit_mmap(). o Fix scanmem(). o Fix clear_active_bh(), a ~ was missing causing weak performance. o Remove experimental cache instructions from stackframe.h. It wasn't improving performance as I was hoping. o Shrink the size of the exception handler routines in uaccess.h. o Cleanup, remove dead code in various files.
* o Merge with Linux 2.1.90.Ralf Baechle1998-03-1854-144/+308
| | | | | o Divide L1 cache sizes by 1024 before printing, makes the numbers a bit more credible ...

* Look Ma' what I found on my harddisk ...Ralf Baechle1998-03-17456-15715/+54153
| | | | | | | o New faster syscalls for 2.1.x, too o Upgrade to 2.1.89. Don't try to run this. It's flaky as hell. But feel free to debug ...
* Timer code rework. Done so far:Ralf Baechle1998-03-111-16/+18
| | | | | | | | | | | | | | | | | o Fix interrupt handler to not loose cycles o Warn about lost interrupts. o Fix calibration of the R4000 CPU timer. Still to do: o General cleanup of the timer code o Microsecond timers for the Indy o The calculated values for r4k_offset are still off by ~480 from the theoretical values. That means we're going to loose about 46 s per day. Are the crystals that bad or is there still a bug hidden somewhere? Maybe an option to set r4k_offset to a user supplied value might help? o Handle lost interrupts more gently so we don't loose time. o Handle 100MHz R4000 count / compare bug.
* And one final dose of tasteless hacks and everything else ...Ralf Baechle1998-03-041-2/+3

* More Second level cache changes. Guess now you understand why I saidRalf Baechle1998-03-046-84/+83
| | | | it's not sooo trivial ...
* - Some small cleanupsRalf Baechle1998-03-045-9/+259
| | | | | - The core of the new second level cache handling for Indy style l2 caches was missing ...
* Cache fixes, part #1.Ralf Baechle1998-03-034-322/+116

* Upgrade to 2.1.73.Ralf Baechle1998-03-0356-27845/+3628
|
* added restart codeThomas Bogendoerfer1998-01-101-3/+21
|
* - removed wrong comments about remapped interruptsThomas Bogendoerfer1997-12-291-23/+11
| | | | | | | - removed unmasking of interrupts, because that is now done in kernel/irq.c; if we don't do it there, we can't autoprobe interrupts. this fix should also be done in all the other int-handler.S - fixed problem with interrupts > 7
* added unmask_irq() to do_IRQ() to fix autoprobing of interrupts possibleThomas Bogendoerfer1997-12-291-1/+2

|
* Merge with Linux 2.1.72, part 2.Ralf Baechle1997-12-1619-1641/+0
| | | | | | The new signal code with exception of the code for the rt signals. The definitions in <asm/siginfo.h> and <asm/ucontext.h> are currently just stolen from the Alpha and will need to be overhauled.
* Merge with Linux 2.1.72, part 1.Ralf Baechle1997-12-1665-1672/+2987

* 1. inventory support.Miguel de Icaza1997-09-211-21/+105
| | | | | | 2. Autogrow mmap flag for irix binaries bad taste hack. 3. fixed irix stat32 4. IRIX_ALLOC_SP fcntl ignored.
* Pass the ioctls down to the Linux kernel when the irix_ioctl does notMiguel de Icaza1997-09-211-1/+5

* Map the PRDA page on IRIX processesMiguel de Icaza1997-09-211-0/+35

* include irixinv in the compilationMiguel de Icaza1997-09-211-1/+2
|
* IRIX inventory support. Right now it has hardcoded my machine'sMiguel de Icaza1997-09-211-0/+80
| | | | | | information. This needs to be fixed at least to report the proper graphics capabilities on the machine. Optimally, we should scatter the right calls to the inventory all over the kernel source.
* Support for the Nevada. Cleanup.Ralf Baechle1997-09-171-38/+6

* - Set caching mode for KSEG0 to cached-noncoherent for all machines.Ralf Baechle1997-09-122-35/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some MIPS boxes the firmware doesn't do that for us. - We still had two unprotected loads in the sys_sigrestore(2). Use __get_user(). - Handle QED-style L1 caches != 16kb per cache correctly. - Protect the cacheflush instructions for the signal trampoline just like the loads in __get_user(). Otherwise the following code will result in a nice "Can not handle kernel paging request" message: #include <signal.h> static void hurz(void) { } main() { signal(SIGSEGV, hurz); /* Chainsaw the stack pointer ... */ asm("move $29,%0" : :"r"(0x70000000)); *(int *) 8 = 0; } With the fix applied I still get the error message. The cause of this problem is that gas produces an __ex_table section with wrong contents. Oh well, how good that I have a nice working post 2.8.1 binutils version at home in good ol' Germany ...
* Cleanup.Ralf Baechle1997-09-121-18/+1

* Remove files that were removed between 2.1.49 and 2.1.55. SomehowRalf Baechle1997-09-1224-535/+0
| | | | my script to do that broke :-(
* Merge with Linux 2.1.55. More bugfixes and goodies from my privateRalf Baechle1997-09-12203-4743/+23642

* Removed the autodestruct prevention mechanisms, now that we'reMike Shaver1997-09-112-9/+2
| | | | grown-up enough to not cause HW catastrophe.

* Added skeletal support for /dev/usema and /dev/usemaclone.Mike Shaver1997-08-101-37/+82
| | | | | | | | | | | | | | Still need to figure out how to do SVR-style clone devices with fops->open(), and I need a good poll() tutorial. =) Other than that, I think I know how to do: /dev/usemaclone open()ing, poll()ing /dev/usema ioctls: - UIOCATTACHSEMA - UIOCBLOCK - UIOCUNBLOCK Also, some minor additions to sysirix.c:syssgi().
