2008-05-13	CRIS: Improve TLB management and handle delayslots at page boundaries.	edgar_igl	1	-6/+13
	* Dont flush the entire qemu tlb when the $pid changes. Instead we go through the guests TLB and choose entries that need to be flushed. * Add env->dslot and handle delayslots at pageboundaries. * Remove some unused code. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@4450 c046a42c-6fe2-441c-8c8c-71466251a162
2008-05-06	CRIS MMU Updates	edgar_igl	1	-2/+9
	* Add support for exec faults and for the k protection bit. * Abort if search_pc causes recursive mmu faults. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@4349 c046a42c-6fe2-441c-8c8c-71466251a162
2008-05-02	CRIS updates:	edgar_igl	1	-35/+43
	* Support both the I and D MMUs and improve the accuracy of the MMU model. * Handle the automatic user/kernel stack pointer switching when leaving or entering user mode. * Move the CCS evaluation into helper funcs. * Make sure user-mode cannot change flags only writeable in kernel mode. * More conversion of the translator into TCG. * Handle exceptions while in a delayslot. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@4299 c046a42c-6fe2-441c-8c8c-71466251a162
2008-03-14	* Add a model of the ETRAX interrupt controller.	edgar_igl	1	-56/+51
	* Clean up the interrupt handling a bit. * Connect some NOR flash to the test board. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@4055 c046a42c-6fe2-441c-8c8c-71466251a162
2008-03-01	* target-cris/op.c: Make sure the bit-test insn only updates the XNZ flags.	edgar_igl	1	-10/+8
	* target-cris/helper.c: Update ERP for user-mode simulation aswell. * hw/etraxfs_timer.c: Support multiple timers. * hw/etraxfs_ser.c: Multiple ports, the data just goes to stdout. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@4004 c046a42c-6fe2-441c-8c8c-71466251a162
2008-02-28	More consistent naming for CRIS register-number macros.	edgar_igl	1	-12/+9

2007-10-28	Use the shiny new clz helpers.	ths	1	-2/+2

2007-10-14	Replace is_user variable with mmu_idx in softmmu core,	j_mayer	1	-4/+4
	allowing support of more than 2 mmu access modes. Add backward compatibility is_user variable in targets code when needed. Implement per target cpu_mmu_index function, avoiding duplicated code and #ifdef TARGET_xxx in softmmu core functions. Implement per target mmu modes definitions. As an example, add PowerPC hypervisor mode definition and Alpha executive and kernel modes definitions. Optimize PowerPC case, precomputing mmu_idx when MSR register changes and using the same definition in code translation code. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@3384 c046a42c-6fe2-441c-8c8c-71466251a162
