| Revision | | Date | Author | Comments |
| 1.7 |
| 26-Jul-2020 |
simonb | Use EIMR/EIRR regs definitions from <mips/cpuregs.h>
|
| 1.6 |
| 07-Jun-2015 |
matt | Define COP0 register that use select value in <mips/cpuregs.h>
Use those new definitions
|
| 1.5 |
| 14-Apr-2011 |
matt | branches: 1.5.14; 1.5.32;
Use .set arch=xlr to access RMI specific instructions.
|
| 1.4 |
| 14-Apr-2011 |
cliff | - fix RCSID
- add rmixl_eirr_ack() to ack the EIRR, using COP0_SYNC & JR_HB_RA as needed
- in rmixl_cpu_trampoline, remove old KSEG0 address reconstruction
of trampoline args pointer, and comment/explain the new way
- also in rmixl_cpu_trampoline, remove old watchpoint hack used for debugging

| 1.3 |
| 20-Feb-2011 |
matt | Merge forward from matt-nb5-mips64.
|
| 1.2 |
| 14-Dec-2009 |
matt | branches: 1.2.4; 1.2.6; 1.2.8; 1.2.10;
Merge from matt-nb5-mips64
Merge mips-specific arch files.
|
| 1.1 |
| 13-Nov-2009 |
cliff | branches: 1.1.2;
file rmixl_subr.S was initially added on branch matt-nb5-mips64.
|
| 1.1.2.12 |
| 19-Jan-2012 |
matt | KX needs to be enabled for n32
|
| 1.1.2.11 |
| 06-Dec-2011 |
matt | Use MIPS_COP_0_OSSCRATCH instead $22
|
| 1.1.2.10 |
| 03-Dec-2011 |
matt | Rework things a bit for the XLR/XLS/XLP TLB. Before dealing with the TLB when
MP on the XL?, disable interrupts and take out a lock to prevent concurrent
updates to the TLB. In the TLB miss and invalid exception handlers, if the
lock is already owned by another CPU, simply return from the exception and
let it continue or restart as appropriate. This prevents concurrent TLB
exceptions in multiple threads from possibly updating the TLB multiple times
for a single address.
|
| 1.1.2.9 |
| 26-May-2011 |
matt | Add MIPS64_RMIXL (XLR/XLS) and MIPS64R2_RMIXL (XLP). This allows the kernel
to treat this special which is needed for MP support. When accessing the TLB,
always lock the TLB before hand. If in the miss handlers, the TLB is already
locked let trap deal with the exeception.
|
| 1.1.2.8 |
| 29-Apr-2011 |
matt | Major merge to/from current.
Adds MIPS32/MIPS64 R2 support (24k, 74k, etc.) including COP0_USERLOCAL
Adds support for emulation of rdhwr $3,$29 instruction.
Major cleanup of SMP code. (stable on multi-core / single thread per core)
llsc locking code only used in MP capable kernels.
|
| 1.1.2.7 |
| 13-Apr-2010 |
cliff | add TNF License and copyright.
|
| 1.1.2.6 |
| 22-Mar-2010 |
cliff | - in rmixlfw_wakeup_cpu, properly nuke the upper half of sp
before OR-ing in KSEG0_START. This is only needed in _LP64 case.
- in rmixl_cpu_trampoline:
trampoline args addr needs reconstructing the upper half only in _LP64 case.
delete set of MIPS_SR_INT_IE bit.
use REG_L instead of PTR_L to load trampoline args
so we get 64 bit loads in both 32 and 64 bit kernels.
|
| 1.1.2.5 |
| 21-Mar-2010 |
cliff | - add rmixlfw_wakeup_cpu, performs callback to RMI firmware wakeup function
- add rmixl_cpu_trampoline, entry point for CPU wakeup following
RMI firmware wakeup callback.
|
| 1.1.2.4 |
| 10-Feb-2010 |
cliff | save gp and t8 before callback to firmware
|
| 1.1.2.3 |
| 24-Jan-2010 |
cliff | - cpu_rmixl_attach calls cpu_setup_trampoline to get control of
subordinate CPUs from firmware by using the 'wakeup' callback method
and into cpu_wakeup_trampoline where they just spin pending further work.
- the callback requires re-basing the stack pointer to be in KSEG0,
done in asm subroutine rmixlfw_wakeup_cpu
|
| 1.1.2.2 |
| 31-Dec-2009 |
matt | Indicate that some RMI mfcr/mtcr can't be used in O32
|
| 1.1.2.1 |
| 13-Nov-2009 |
cliff | - rmixls_subr.S is replaced by rmixl_subr.S
- those subroutine names changed accordingly
