* - IOC3 driver now will panic when encountering a RX/TX PCI DMA error.Ralf Baechle2000-01-171-7/+10
| | | | | | | | | - IOC3 driver does no longer use GFP_DMA which given the _very_ small number of available GFP_DMA pages might have deadlocked the system. - First cut of Origin support. Last minute change: Do no longer use ARC memory / MD hub memory configuration information but klconfig.h stuff. Simpler, faster, shorter. - Zillions of MIPS64 fixes.

* o Moved remote GDB setup from indy_int.c to setup.c.Ulf Carlsson1999-06-122-37/+80
| | | | | o Fixed (rewrote) the remote GDB init code so that one may boot the debug kernel without the debug features. o Fixed some other stuff as well.

* o Removed indy_pbus.c neither it worked nor it was really neededUlf Carlsson1999-02-071-2/+2
| | | | | | | | | | | o Moved the relevant parts right into hal2.c o Found at that I had forgot to setup pbus.cfgdma, I think I'm doing that correctly now o Changed hpcreg pbus_dmacfgs[128][10] to hpcreg pbus_dmacfgs[10][128] in sgihpc.h. It seems to be eiser addressed that way o I'm now using a flags variable instead of +1000 variables! I don't know CVS well enough yet. I'll remove the bogus files in the next burst!

* o Merge with Linux 2.1.116.Ralf Baechle1998-08-257-16/+25
| | | | | o New Newport console code. o New G364 console code.

* - Reformat ptrace.c for readability.Ralf Baechle1998-07-161-3/+1
| | | | | | | | | | | | | | - Handle lazy fpu context switches correctly for ptrace(2). - Don't read $fcr31 on context switch, it's pure bloat. - New processes get $fcr31 initialized to no exceptions. - First beginnings of floating point support kernel code. For now we only can handle cvt.w.s and cvt.w.d instructions where the source register is a NaN, infinity or denorm. This is good enough to get Mozilla up. - Don't send SIGFPE on every floating point instruction we don't know how to handle, rather just complain. - Cleanup headerfile inclusions in the HPC3 code. - Fix the definition of PAGE_NONE.
* o Support for the front panel on the Indy. The panel work now as aRalf Baechle1998-07-104-45/+194
| | | | | | | | | | | | | | | | | | | | | | | | | user would expect it to work, like under IRIX with the exception that the machine doesn't freeze solid as long as the button is pressed. o Realtime clock driver (CONFIG_SGI_DS1286) for the Indy. Includes /proc/rtc interface which tells you everything about your RTC which you never wanted to know. You have to configure this driver into your kernel or you won't be able to set your RTC. o Some cleanup of the RTC interfaces in Linux, RTC does no longer mean PC-style RTC. The userland interface definitions are now in <linux/rtc.h>. We still need some more cleanup until we can enable several RTC drivers. o Virtual aliasing fixes for ptrace(2). o Add ptrace(2) interface definitions needed to build GDB to <asm/ptrace.h>. o Revert to some older routines, the newer optimized ones are buggy. o On panic the Indy LED will be blinking fast crying to the admin passing by [music from Rocky Horror show] ``fix me, fix me, fix me''. o On panic the power button will only reboot the machine, not power it down. That's probably more what people want it to do. o Remove some old files. o Did I tell you that CVS is buggy?
* o Merge with Linux 2.1.100.Ralf Baechle1998-06-305-36/+56
| | | | | | | | | | | | | | | | | | o Cleanup the machine dependencies of floppy and rtc. The driver for the Dallas thingy in the Indy is still missing. o Handle allocation of zero'd pages correct for R4000SC / R4400SC. o Page colouring shit to match the virtual and physical colour of all mapped pages. This tends to produce extreme fragmentation problems, so it's deactivated for now. Users of R4000SC / R4400SC may re-enable the code in arch/mips/mm/init.c by removing the definition of CONF_GIVE_A_SHIT_ABOUT_COLOURS. Should get them somewhat further - but don't shake to hard ... o Fixed ptrace(2)-ing of syscalls, strace is now working again. o Fix the interrupt forwarding from the keyboard driver to the psaux driver, PS/2 mice are now working on the Indy. The fix is somewhat broken as it prevents generic kernels for Indy and machines which handle things different. o Things I can't remember.
* o Merge with Linux 2.1.99.Ralf Baechle1998-05-072-4/+23
| | | | | o Fix ancient bug in the ELF loader making ldd crash. o Fix ancient bug in the keyboard code for SGI, SNI and Jazz.
* o New memset. Fastest in town for size > 6 bytes.Ralf Baechle1998-05-042-50/+11
| | | | | | | | | | | | | | | | | | | | | | | o New clear_user. o Memcpy now efficiently copies the (src^dest)&3 != 0. o Memmove new correctly deals with overlaps o Rewrite csum_partial in assembler. o Rewrte csum_partial_from_user in assembler. o __copy_user is now integrated with memcpy. o get_user now returns a zero value on error. o copy_from_user now clears the destination buffer on error. o strncpy_user now has a more efficient caller routine. o strlen_user now has a more efficient caller routines and is faster. o The unaligned handler is now much cleaner. It's now also save from interrupt. Some more esotheric bugs fixed as well. o Don't export bcopy anymore, it's now a inline function. o Delete ancient junk from the first days of Linux/MIPS. o Delete dead code in indy_sc.c. o Including the IDE driver doesn't crash an Indy anymore. o Eleminate active_ds. We now use current_ds directly in the thread structure which is faster and threadsafe. Saves almost 2kb on the kernel. o Serial console should work again.
* o Merge with Linux 2.1.91.Ralf Baechle1998-04-0520-92/+122
| | | | | | | | | o First round of bugfixes for the SC/MC CPUs. o FPU context switch fixes. o Lazy context switches. o Faster syscalls. o Removed dead code. o Shitloads of other things I forgot ...
* o Speedup syscalls. Now 816ns per syscall. Yes, nanoseconds and goodbyeRalf Baechle1998-03-272-42/+65
| | | | | | | | | | Pentium :-) o Little bit smarter handling of unimplemented exceptions. o Fix FPU context switches. o Fix reboot / halt. Powerdown in software still doesn't work. o Fix the fix for handling of return values of interrupted syscalls. o Handling of the Indy second level cache now works as spec'ed. Purely cosmentic, this was not causing any problems.
* o Fix handling of interrupted syscalls.Ralf Baechle1998-03-222-6/+6
| | | | | | | | | | | | 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.
* Look Ma' what I found on my harddisk ...Ralf Baechle1998-03-174-10/+13
| | | | | | | 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.
* More Second level cache changes. Guess now you understand why I saidRalf Baechle1998-03-042-43/+16
| | | | it's not sooo trivial ...
* - Some small cleanupsRalf Baechle1998-03-042-3/+251
| | | | | - The core of the new second level cache handling for Indy style l2 caches was missing ...
* Merge with Linux 2.1.72, part 1.Ralf Baechle1997-12-161-0/+1
