Gabe Black c3381167c9 ARM: Make the MPUIR register report that 1 unified data region is supported. 2010-06-02 12:58:10 -05:00
Gabe Black 3aa8faf177 ARM: Ignore/warn on accesses to the BPIALLIS and BPIALL registers. 2010-06-02 12:58:10 -05:00
Gabe Black 68f2908a70 ARM: Ignore/warn when CSSELR or CCSIDR are accessed.
These registers provide information about the caches. Since we can't provide
that information, these will be harmlessly inert.

Gabe Black 741b243260 ARM: Ignore/warn access to the bpimva registers. 2010-06-02 12:58:09 -05:00
Gabe Black 8a7f60194e ARM: Ignore/warn on accesses to the dccmvac register. 2010-06-02 12:58:09 -05:00
Gabe Black a483d44d9f ARM: Ignore/warn on accesses to icimvau. 2010-06-02 12:58:09 -05:00
Gabe Black 630f309a77 ARM: Ignore/warn on iciallu. 2010-06-02 12:58:09 -05:00
Gabe Black d618121670 ARM: Ignore/warn on ICIALLUIS. 2010-06-02 12:58:09 -05:00
Gabe Black e658b6fed4 ARM: Add support for the clidr register.
This register will always report 0 caches as implemented. It's not clear how
to find out how many there really are when dealing with an arbitrary
hierarchy.

Gabe Black 896c7617c4 ARM: Decode the unimplemented data barrier CP15 accesses.
These are CP15DSB (Data Synchronization Barrier), and CP15DMB (Data Memory
Barrier).

Gabe Black af6b1667e9 ARM: Implement a stub of CPACR.
This register controls access to the coprocessors. This doesn't actually
implement it, it allows writes which don't turn anything off. In other words,
it allows the simulated program to ask for what it already has.

Gabe Black 35f0c01fea ARM: Decode the unimplemented cp15 instruction barrier. 2010-06-02 12:58:08 -05:00
Gabe Black 7932b86298 ARM: Ignore accesses to DCCIMVAC. 2010-06-02 12:58:08 -05:00
Gabe Black 6ae4d34a12 ARM: Allow accesses to the software thread id registers. 2010-06-02 12:58:08 -05:00
Gabe Black 54850e4d23 ARM: Allow accesses to the contextidr register. 2010-06-02 12:58:08 -05:00
Gabe Black 221e0ac523 ARM: Warn about and ignore accesses to DCCISW.
This register is supposed to "Clean and invalidate data or unified cache line
by set/way." Since there isn't a good way to do that, we'll just ignore these
and warn about it.

Gabe Black 6aa229386d ARM: Implement a function to decode CP15 registers to MiscReg indices. 2010-06-02 12:58:08 -05:00
Gabe Black bd8812cf99 ARM: Replace the "never" condition with the "unconditional" condition. 2010-06-02 12:58:00 -05:00
Gabe Black 9ef82c0bc4 ARM: Track the current ISA mode using the PC. 2010-06-02 12:57:59 -05:00
Gabe Black e2ab64543b ARM: Define a mask to differentiate purely CPSR bits from CondCodes bits. 2009-11-14 19:22:30 -08:00
Gabe Black 2e28da5583 ARM: Implement fault classes.
Implement some fault classes using the curriously recurring template pattern,
similar to SPARCs.

Gabe Black d188821d37 ARM: Add in more bits for the mon mode. 2009-11-08 02:01:02 -08:00
Gabe Black 4079792f2b ARM: Add in spots for the VFP control registers. 2009-07-27 00:53:10 -07:00
Gabe Black 38d8bc64ba ARM: Fill out the printReg function. 2009-06-26 22:01:34 -07:00
