[ES40-developers] Version 0.18 release

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Hello everyone,

I am very pleased to announce that version 0.18 of the ES40 Emulator
has been released. We've done our best to improve compatibility of the
emulator with various host and guest operating-systems, we have
working SCSI-support for OpenVMS, improved IDE and Network
implementations, and we have improved performance.

The new release can be downloaded - as always - from
http://sourceforge.net/projects/es40.

The complete change log for the new version is as follows:

version 0.17 -> 0.18
Version 0.18 contains a lot of compatibility fixes, both with host and
guest operating systems.

    * Merged Brian wheeler's New IDE code into the standard
controller. NewIde class has disappeared. (04-mar-2008, Camiel
Vanderhoeven)
    * Support some basic MP features. (CPUID read from C-Chip MISC
register, inter-processor interrupts) (04-mar-2008, Camiel
Vanderhoeven)
    * Allow memory sizes over 1 GB. (02-mar-2008, Brian Wheeler)
    * Natural way to specify large numeric values ("10M") in the
config file. (02-mar-2008, Camiel vanderhoeven)
    * Add BREAKPOINT INSTRUCTION command to IDB. (29-feb-2008, Brian Wheeler)
    * Restart serial port connection if lost. (29-feb-2008, Brian Wheeler)
    * Fix RMC reported psu and temperature status. (29-feb-2008, Brian Wheeler)
    * Compute SROM checksum for network interface. Tru64 needs this.
(29-feb-2008, Brian Wheeler)
    * Fix vms boot problems from ide cdrom and make Tru64 installation
possible by: a) Clearing the busmaster active bit when the bit 1 is
written to the busmaster status register; and b) Attempting to refire
the interrupt if the driver seems to have missed it. (27-feb-2008,
Brian Wheeler)
    * Major rewrite of NIC code. Real internal loopback support, ring
queue for incoming packets, and various other improvements.
(26-feb-2008, David Hittner)
    * Improvements to backtrace functionality on GNU systems
(26-feb-2008, Brian Wheeler)
    * Better config file syntax checking and error reporting.
(26-feb-2008, Brian Wheeler)
    * Moved DMA code into it's own class (CDMA). (26-feb-2008, Camiel
Vanderhoeven)
    * Shut down display refresh thread when emulator exits.
(20-feb-2008, David Leonard)
    * Return SYSTEM RESOURCE FAILURE sense if dato/dati buffer size is
exceeded in SCSI operations. (20-feb-2008, David Leonard)
    * Support MSF in READ TOC scsi command. (20-feb-2008, Brian Wheeler)
    * Show disk creation progress. (20-feb-2008, David Leonard)
    * Avoid 'Xlib: unexpected async reply' errors on Linux/Unix/BSD's
by adding some thread interlocking. (20-feb-2008, David Leonard)
    * GNU compiler support on Windows. (20-feb-2008, Alex)
    * HCI register space for UISB added. (18-feb-2008, Brian Wheeler)
    * Added vital product data page 0 (Required for Tru64).
(18-feb-2008, Brian Wheeler)
    * The READ CAPACITY scsi command now properly returns the number
of the last LBA (n-1); not the number of LBA's (n). INITIALIZE now
works properly on a scsi disk. (18-feb-2008, Camiel Vanderhoeven)
    * Added READ_LONG scsi command, and support for MODE_SENSE
changeable parameter pages. (last bit needed to get SCSI working on
OpenVMS) (16-feb-2008, Camiel Vanderhoeven)
    * The owner of the SCSI bus is allowed to re-arbitrate for it.
(16-feb-2008, Camiel Vanderhoeven)
    * Added Symbios 53C810 SCSI controller. (16-feb-2008, Camiel Vanderhoeven)
    * Moved keyboard code into it's own class. (CKeyboard).
(12-feb-2008, Camiel Vanderhoeven)
    * Show originating device name on memory errors. (08-feb-2008,
Camiel Vanderhoeven)
    * Set default keyboard translation to scanset 3 (PS/2).
(08-feb-2008, Camiel Vanderhoeven)
    * On GNU systems, display a backtrace when a segmentation fault
occurs, and DEBUG_BACKTRACE has been defined. (07-feb-2008, Brian
Wheeler)
    * Fixed registration of ROM expansion address. (06-feb-2008,
Camiel Vanderhoeven)
    * Check for FPEN in old floating point code. (06-feb-2008, Camiel
Vanderhoeven)
    * Proper interrupt handling in serial port device. Fixes an
initialization bug spotted by David Hittner. (06-feb-2008, Camiel
Vanderhoeven)
    * Disable unaligned access check alltogether; it doesn't work
properly for some reason. (05-feb-2008, Camiel Vanderhoeven)
    * The new floating point code (21-jan-2008) has some unidentified
problems. The OpenVMS installation routine fails with this new code.
For now, the old floating point code has been restored, and the new
floating-point code is used only when HAVE_NEW_FP has been defined.
The new code should be fixed, so we can take advantage of floating
point exceptions. (05-feb-2008, Camiel Vanderhoeven)
    * Display a message when system initialization has failed.
(05-feb-2008, Brian Wheeler)
    * Put X64 around 64-bit constants in DO_CVTQL. (compilation issue
on some Linux'es) (05-feb-2008, Camiel Vanderhoeven)
    * Corrected a typo in the definition of PCI_PTE_SHIFT (2 should be
12) that caused an OpenVMS procgone bugcheck. (04-feb-2008, Camiel
Vanderhoeven)
    * Completed LPT support so it works with FreeBSD as a guest OS.
(02-feb-2008, Brian Wheeler)
    * Avoid unnecessary shift-operations to calculate constant values.
(01-feb-2008, Camiel Vanderhoeven)
    * Improved speed by remembering the number of instructions left in
current memory page, so that the translation-buffer doens't need to be
consulted on every instruction fetch when the Icache is disabled.
(30-jan-2008, Camiel Vanderhoeven)
    * Remember separate last found translation-buffer entries for read
and write operations. This should help with memory copy operations.
(29-jan-2008, Camiel Vanderhoeven)
    * Avoid interrupts from the new IDE device that originated while
interrupts were disabled. (29-jan-2008, Brian Wheeler)
    * Improved floating-point exception handling. (28-jan-2008, Camiel
Vanderhoeven)
    * Lifted hardcoded file-size limit of 10,000 bytes for config
file. (26-jan-2008, Camiel Vanderhoeven)
    * Bugfix in the VAX floating point STF and the IEEE floating point
STS instructions. (26-jan-2008, Camiel Vanderhoeven)
    * Don't repeat interrupts from the new IDE controller too soon.
(26-jan-2008, Brian Wheeler)
    * Do unaligned trap only when a page boundary is crossed.
Something is causing alignment traps in the SRM console, with the DAT
bit set to false, and no OS handler in place. Also, when OpenVMS boots
there are alignment traps that shouldn't happen. None of these cross
page boundaries, so we're safe for now. (26-jan-2008, Camiel
Vanderhoeven)
    * Trap on unaligned memory access. The previous implementation
where unaligned accesses were silently allowed could go wrong when
page boundaries are crossed. (25-jan-2008, Camiel Vanderhoeven)
    * Allow specifying autocreate_size on a disk image to have it
created if it doesn't exist. (25-jan-2008, Camiel Vanderhoeven)
    * Added an option to disable the processor Icache. The emulator
runs faster when this is disabled, but that might lead to problems
with some OS'es. (25-jan-2008, Camiel Vanderhoeven)
    * Added do_pci_write and do_pci_read functions to the PCI base
device. (24-jan-2008, Camiel Vanderhoeven, David Hittner)
    * Fixed overflow-detection. (24-jan-2008, Camiel Vanderhoeven)
    * Added missing integer /V instructions (22-jan-2008, Camiel
Vanderhoeven, Bob Supnik)
    * win32 GUI made compatible with older windows SDK. (22-jan-2008,
Camiel Vanderhoeven)
    * New floating-point code (21-jan-2008, Camiel Vanderhoeven, Bob Supnik)
    * Fixed misinterpretation of the INT bit in integer overflow
traps. (Camiel Vanderhoeven, 21-jan-2008)
    * Limited the maximum number of sectors, as the OpenVMS IDE driver
doesn't like 255 sectors. (Camiel Vanderhoeven, 21-jan-2008)
    * Added X11 GUI. (20-jan-2008, Camiel Vanderhoeven)
    * Added win32 GUI. (19-jan-2008, Camiel Vanderhoeven)
    * Run CPU in a separate thread if CPU_THREADS is defined. NOTA
BENE: This is very experimental, and has several problems.
(19-jan-2008, Camiel Vanderhoeven)
    * Replaced sext_64 inlines for performance reasons (18-jan-2008,
Camiel Vanderhoeven, David Hittner)
    * Process device interrupts after a 100-cpu-cycle delay.
(18-jan-2008, Camiel Vanderhoeven)
    * Added ADDL/V instruction (16-jan-2008, David Hittner, Bob Supnik)
    * Fixed some timeouts on new IDE controller. (16-jan-2008, Brian Wheeler)
    * When a keyboard self-test command is received, and the queue is
not empty, the queue is cleared so the 0x55 that's sent back will be
the first thing in line. Makes the keyboard initialize a little better
with SRM. (15-jan-2008, Brian Wheeler)
    * Bugfix regarding double deletion of disk device objects.
(13-jan-2008, Brian Wheeler)
    * New IDE-controller working on big-endian host architectures.
(13-jan-2008, Fang Zhe)
    * Support additional CD-ROM commands. (13-jan-2008, Brian Wheeler)
    * Smart algorithm for determining optimal cylinder/head/sector
disk layout. (13-jan-2008, Camiel Vanderhoeven)
    * End debugger run on Ctrl-C. (12-jan-2008, Brian Wheeler)
    * SCSI Engine added to Disk class. SCSIBus class and SCSIDevice
base class added. (12-jan-2008, Camiel Vanderhoeven)
    * bugfix to ATAPI code in new IDE controller. SRM can now boot
from IDE CD-ROMs. (09-jan-2008, Brian wheeler)
    * ATAPI improvements to new IDE controller. (09-jan-2008, Brian wheeler)
    * Put filename without path in disk model number. (09-jan-2008,
Brian Wheeler)
    * Save disk state to state file. (09-jan-2008, Camiel Vanderhoeven)
    * Use Brian Wheeler's CNewIde class instead of the CAliM1543C_ide
class if HAVE_NEW_IDE is defined. This change will be undone when the
new ide controller will replace the old standard one. (08-jan-2008,
Camiel Vanderhoeven)
    * "Old" IDE-controller working on big-endian host architectures.
(08-jan-2008, Fang Zhe)
    * S3 Trio VGA-card working on big-endian host architectures.

(08-jan-2008, Camiel Vanderhoeven)
    * Added NewIde class. Due to replace the current IDE controller
implementation. (08-jan-2008, Brian Wheeler)
    * PCI scatter/gather DMA memory mapping support added.
