joevt bfd3077bd0 scsicdrom: Check Lun for INQUIRY. 
INQUIRY now returns 0x7f for device type if LUN doesn't match. INQUIRY can get LUN from CDB or from IDENTIFY message.

dingusdev afd8ba8cf2 Slight adjustment for the readme 2024-03-31 15:09:57 -07:00
dingusdev 43d87b4791 Temp revert for icnt_factor 
We should, at minimum, make icnt_factor adjustable. That said, powermax is suggesting we develop a more sophisticated scheduler.

joevt 02a475e113 sc53c94: Remove duplicate bus_obj. 
sc53c94 is a ScsiDevice which has its own bus_obj which is set by register_device.
 2024-03-30 11:56:59 -07:00
joevt 338bbe27a8 scsihd: Implement REQ_SENSE. 
Returns error information stored in class fields: sense, asc, ascq, sksv, and field.
 2024-03-30 11:56:37 -07:00
joevt 44564065f6 scsihd: Changes for MODE_SENSE_6. 
Return CHECK_CONDITION for unsupported page_ctrl or page or subpage.
Handle the all pages code 0x3F.
 2024-03-30 11:56:02 -07:00
dingusdev c54ec7be2d Use memset instead of bzero 2024-03-30 11:19:32 -07:00
joevt 274e380b34 scsicdrom: Allow INQUIRY allocation length != 36. 
Truncate for < 36 and zero fill for > 36.
 2024-03-30 11:16:41 -07:00
joevt e872f08273 scsicdrom: Include invalid field info. 
For CHECK_CONDITION status from READ_CAPACITY_10 and READ_TOC.
 2024-03-30 11:00:01 -07:00
joevt a6fda3b787 scsicdrom: Handle MODE_SENSE_6 unsupported page. 
Return CHECK_CONDITION status instead of abort. To Do: apply change to scshhd.
 2024-03-30 10:59:43 -07:00
joevt a48851888f scsihd: Setup data_ptr for STATUS and MESSAGE_IN. 
bytes_out is used instead of the removed cur_buf_cnt.
data_ptr is setup by prepare_data instead of process_command.
Not sure why scsicdrom doesn't set bytes_out in prepare_data.
 2024-03-30 08:37:10 -07:00
joevt f1abb66f9a atahd: Add STANDBY_IMMEDIATE. 2024-03-30 08:30:37 -07:00
joevt c999c51d77 scsicdrom, scsihd: Check lun. 
READ_CAPACITY_10, READ_6, and READ_10 now checks LUN that is included in CDB and returns a CHECK_CONDITION if it doesn't match.
 2024-03-29 19:12:06 -07:00
joevt 6bb5227ee1 scsihd: Abort if RelAdr bit of READ_10. 
Like scsicdrom does.
 2024-03-29 19:01:42 -07:00
joevt cefe8698da scsihd: Add PREVENT_ALLOW_MEDIUM_REMOVAL. 
Like scsicdrom has.
 2024-03-29 19:01:32 -07:00
joevt 4be6bad526 scsicdrom: Fix compiler warning. 2024-03-29 19:00:38 -07:00
joevt d3c913e384 scsicdrom: Cleanup. 
- Use macros for reading 2 byte or 4 byte big endian data. block_size is assumed to be < 64K so WRITE_DWORD_BE_A will write two leading zeros.
- Scalar pass by value parameters don't need to be const.
- Remove some unnecessary locals.
 2024-03-29 18:53:13 -07:00
joevt a868f4eee4 scsihd: Cleanup. 
Use this qualifier.
Use macros for reading 2 byte or 4 byte big endian data.
 2024-03-29 18:53:04 -07:00
joevt 44da89979f scsihd: Use device name in abort message. 2024-03-29 18:52:52 -07:00
joevt a79f07e4dc scsicdrom: Move mode_select_6. 
Make it a separate method like scsihd. It also checks the incoming param size. If it's zero then the phase is not switched. Is that wrong? Still probably unfinished.
 2024-03-29 18:52:30 -07:00
Maxim Poliakovski e17a96f5ec atirage: break long lines. 2024-03-29 21:21:58 +01:00
joevt 5062508940 scsicdrom: Rename mode_sense_6. 
To match scsihd.
 2024-03-29 07:56:48 -07:00
joevt 9cf91328c1 scsicdrom: Move inquiry info to class fields. 
Like scsihd.
 2024-03-29 07:56:44 -07:00
joevt 6a30ef7017 scsicdrom: Fields inited by parent class. 
They don't need to be reinitialized.
 2024-03-29 07:56:31 -07:00
Maxim Poliakovski 71dabf5334 atahd: break long lines. 2024-03-29 12:46:57 +01:00
joevt 155b8cdad9 atahd: Support inexact CHS. 
The total size needs to have 3 factors cylinders, heads, & sectors. Imagine a disk having a total size with 3 prime factors 3 x 5 x 11. 15 cannot be assigned to heads because that would only leave 11 for sectors and cylinders. Therefore, test all heads and sectors combinations. If the third factor for cylinders is not found, then choose 16 heads, then the minimum number of sectors, and finally the maximum number of cylinders. The loop could be changed to skip values of heads that are not a factor, but it doesn't take any time to try them all.
 2024-03-28 21:07:12 -07:00
joevt 96dc02b249 atahd: Make sure disk is not too big. 2024-03-28 21:07:08 -07:00
Maxim Poliakovski eaddcab0ba atahd: don't register device for empty images. 
Workaround for the case when no hard disk image
was specified. The device instance is still there
but it won't be visible by the guest OS.

joevt d9b02ecd8d ppcmmu: Check 8 byte alignment spanning pages. 2024-03-28 07:53:03 -07:00

joevt 58ed5bb56e ppcexec: Opcode initialization to one function. 
Move all opcode initialization to initialize_ppc_opcode_tables.
Some opcodes are illegal for some processors.
 2024-03-28 07:35:57 -07:00

joevt f55ad323b4 ppcdisasm: Fix order of operands. 
For cntlzw, extsh, extsb.
 2024-03-28 07:09:50 -07:00
joevt 78558e4c52 debugger: Ensure space between opcode and operand. 
Instructions that are 8 characters or longer (such as mtdbat3l) did not have a space between opcode and operand. Now there is always a space. The width of the opcode column is unchanged except for those opcodes that have 8 or more characters.
 2024-03-28 06:54:23 -07:00
