| 2021-06-06 | Fixes for secondary CPU start-up. | Jason Thorpe | 1 | -4/+9 | |
| Changes to make secondary CPU start-up work on NetBSD, which depends on some specific behavior in the architecture specification: - Change the internal swppal() function to take the new VPTPTR and Procedure Value as explicit arguments. Adapt do_start() to the new the new swppal() signature. - In do_start_wait(), extract the new VPTPTR and PV from the relevant HWRPB fields, which will have been initialized by the OS, and pass them to swppal(). - In the SWPPAL PAL call, get the value to stuff into PV (r27) from a4 (r20), and add a comment describing why this implementation detail is allowed by the architecture specification.

| 2021-06-05 | Fix delivery of unaligned access exceptions. | Jason Thorpe | 1 | -1/+1 | |
| In the unaligned access exception vector, actually pass the return PC in the exception frame. This is required in order for unaligned access fixup handlers in the operating system to work.

| 2019-03-25 | Report machine checks to the kernel | Richard Henderson | 1 | -82/+94 | |
| Use a minimally populated logout frame. This is good enough to handle probing of devices using the kernel's mcheck_expected. Signed-off-by: Richard Henderson <rth@twiddle.net> | |||||
| 2019-01-08 | Do not increment PC for OPCDEC | Richard Henderson | 1 | -2/+1 | |

| 2011-05-01 | Add copyright information. | Richard Henderson | 1 | -202/+25 | |
| 2011-04-28 | Rearrange Cserve. Add QMU clock/alarm related entry points. | Richard Henderson | 1 | -16/+44 | |

| 2011-04-25 | Fix error in SWPCTX code. | Richard Henderson | 1 | -2/+2 | |
| 2011-04-22 | Implement CallPal_Cserve. | Richard Henderson | 1 | -4/+59 | |
| This is just good enough to handle the cserve_ena/dis used by the Linux kernel for managing interrupts. | |||||

| 2011-04-13 | PCBB.PTBR contains a page frame number, not a physical address. | Richard Henderson | 1 | -1/+5 | |
| 2011-04-13 | Rely less on initialized data. | Richard Henderson | 1 | -12/+34 | |
| (1) Don't statically initialize HWRPB and PCBB. (2) Use SwpPal at the end of do_start to install the PCBB and PTBR, rather than setting those up in __start in PALmode. (3) Use -mbuild-constants to prevent the compiler using static data. | |||||
