Driver ACPI

ACPI Driver Software Package This package contains the following files, known as the ACPI Driver Software, from the ACPI Driver Project. You must always use matched versions of all the files in this package. You cannot mix some files from previous versions. ACPI.PSD - The Platform Specific Driver ACPI32.DLL - The Application interface to ACPI.PSD AcpiDaemon.exe - A helper application. Handles throttling, logging. APM.ADD - A interface for emulating legacy APM calls with ACPI AcpiStat.exe - Outputs some statistics from ACPI.PSD ACPID.CFG.SAMPLE - Sample AcpiDaemon configuration file IASL.EXE - ASL compiler AcpiDump.exe - Dumps ACPI tables For your convenience, this Warpin package also includes updates in separate packages that are not part of the ACPI Driver project and are not related to ACPI or the driver. The updated files, each in their own package, are: * DOSCALL1.DLL * TCPIP32.DLL * IBMKBD.SYS * PSCOM.SYS * RESOURCE.SYS * SOCKETSK.SYS Note that APM.ADD is the APM compatibility support using ACPI included in this package. If you have the old APM.SYS installed, you must remove it from your config.sys. The Warpin package checks this for you. ACPID.CFG is formatted differently than older versions. Check the ACPID.CFG.SAMPLE file for the new format. You should use the newest acpid.cfg.sample as your acpid.cfg and modify it to enable your chosen parameters. The daemon will default to reasonable settings if acpid.cfg is not present. This software will run with full functionality on the following kernels: Arca Noae 14.202 SMP Retail Arca Noae 14.201 SMP Retail Arca Noae 14.104b SMP Debug Arca Noae 14.104c SMP Debug This software will run on the following kernels but some advanced features such as support for 64 interrupts will not work: Arca Noae 14.200 SMP Retail Arca Noae 14.104a SMP Debug Arca Noae 14.200 W4 Retail IBM 14.104a SMP Retail IBM 14.105 SMP Retail IBM 14.106 SMP Retail IBM 14.104a W4 Retail IBM 14.105 W4 Retail IBM 14.106 W4 Retail You must also be using either the IBM or Arca Noae loader.

Installation ============ To install this package, simply run the installation executable. Leave all the defaults as-is. When installing this package always answer to overwrite existing files and always answer to unlock any files in use. This installer package is not supported on systems using anything other than CMD.EXE as the default OS/2 shell. Do not use the old Acpi Wizard (AcpiWzrd.exe) to install or configure this software. It is recommended that you backup your boot partition before installing this software. You should not attempt to uninstall this software by using Warpin since that will not revert your system back to the way it was and can make your system unbootable. You can stop using this software by simply commenting out the relevant lines in your config.sys. In addition to installing the requested software, the Warpin Installer for this package will make the following changes to your system: 1. Remove POWERMAN.EXE from your CONFIG.SYS, if it exists. 2. Remove APM.SYS from your CONFIG.SYS, if it exists. 3. Remove VAPM.SYS from your CONFIG.SYS, if it exists. 4. Remove OS2APIC.PSD from your CONFIG.SYS, if it exists. 5. Remove any duplicate copies of ACPI.PSD from \ and \OS2 on your boot disk. 6. Remove any duplicate copies of APM.ADD from \ and \OS2 on your boot disk. Note that the Warpin installer only removes certain entries from your CONFIG.SYS. It does not actually uninstall these programs. These programs and their data will still be present on your disk.

Fixed problem with Award ACPI and possibly other similar vendors. Changes in 3.19.16 - Jul-2011 - David Azarewicz ----------------------------------------------- Updated the ACPICA to version 20110623. Implemented a workaround in AcpiDaemon to ignore defective SLPB devices. Note that this workaround just ignores the events generated by defective SLPB devices, but the events still happen. If AcpiDaemon logging is enabled these events will still be logged at the rate of about 1 every 2 seconds and the logfile could fill up your disk. Documentation updates Warpin installer improvements and fixes. 3.19.15 - David Azarewicz ------------------------- Changed PCI bus scan to scan all busses even if bridges are not found for those busses. Rewrote the ACPI root bridge detection routine to properly handle systems with multiple root bridges. Fixed the ACPI device tree walk routine to better accomodate variations in different vendor's ACPI tables. Fixed a trap due to a spurious interrupt on some Multi-CPU systems when running in Mode 1. Added a feature to the Power Manager to turn off (halt) CPUs when the system is idle. Fixed more bugs in APM.ADD. Changed some debug output. Reworked the routines for debug video output.

Changed to only override _OS_ if /OS= is specified on the command line. Documentation updates. Added Power Manager documentation. Warpin Installer fixes. 3.19.14 - David Azarewicz ------------------------- Fixed an error in Local APIC ID assignment for multi-processor systems. Documentation updates. 3.19.13 - David Azarewicz ------------------------- DLL code cleanup and fix memory leak. Rearranged some functions in DLL to try to workaround a long time existing problem in the xworkplace/ecenter enhanced shutdown power off (page not present problem). Even with this workaround, the xworkplace/ecenter enhanced shutdown is still broken and the power off function may still not work in some cases until xworkplace/ecenter gets fixed. Some work on suspend/resume. It might work, but it is still not finished. Some changes to acpid.cfg. See new acpid.cfg.sample. Documentation updates. There are still a few known problems on a few remaining oddball systems. These problems are still being worked on. However, with this version, this PSD should work well on over 90% of all systems. For now, beware of Acer equipment, some Dell equipment, and systems like the IBM xSeries servers. 3.19.12 - David Azarewicz ------------------------- Fix for defective old AMD/VIA APICs or BIOS. The PSD now checks and reassigns APIC IDs if needed. /BAUD=n switch added for debug output Some changes to acpid.cfg. See new acpid.cfg.sample. Assign interrupts to all devices even if the BIOS says they are disabled. Fixup enable bits for all devices (Fixes some systems with a defective BIOS like Acer) The PSD may now modify the PCI configuration in all modes including modes 0 and 1. Some work on suspend/resume. It is still not working. APM.ADD may have problems. Use it at your own risk. 3.19.11 - David Azarewicz ------------------------- Fixed ACPI memory allocation and mutex helper routines. Major changes to the embedded controller code. Communication with the embedded controller now works correctly. Major changes to event handling code. Documentation was updated. There is still much work to be done in APM.ADD and AcpiDeamon.exe so these modules may not work correctly yet. Suspend/resume is known to be broken. 3.19.10 - David Azarewicz ------------------------- Fixed interrupt routing for link based systems. Minor changes to interrupt startup code including: changed the trigger type for interrupt 8, masked interrupt 2 in Symmetric mode. Removed temporary /NV switch. NVidia systems now work properly. The NVidia chipset was never actually the problem. It was the BIOS. Added temporary /TEST switch. This switch should only be used at the request of the developer. Documentation was updated There is still much work to be done in APM.ADD and AcpiDeamon.exe so these modules may not work correctly yet. 3.19.09 - David Azarewicz ------------------------- Fixed a bug in APM.ADD that could cause a trap on startup. Changed some debug output. Temporarily added /NV switch for debugging NVidia hardware. 3.19.08 - David Azarewicz ------------------------- Interrupts for unused PCI devices are now disabled. Acpi startup reorganized, again. 3.19.07 - David Azarewicz ------------------------- Acpi startup reorganized. PCI configuration testing APM.ADD now accepts /DBGLVL=n switch, default=0 3.19.06 - David Azarewicz ------------------------- Acpi interrupt setup fixed. PCI configuration fixes. /FS switch removed 3.19.05 - David Azarewicz ------------------------- update.cmd was added to make updating a system easier and less error prone to typos. Documentation was updated. 3.19.04 - David Azarewicz ------------------------- The PSD now properly detects the initial interrupt configuration as setup by the BIOS so that the transition to eCS works properly (or at least better). The PCI configuration logic has been cleaned up and rewritten. It is better now but not complete yet. Several of the toolkit functions have been fixed. Powerdlg.exe was added to the source tree and the distribution. 3.19.03 - David Azarewicz ------------------------- More work on interrupt mode setup. The PSD now detects APIC versions and configures itself appropriately. If IOAPICs are detected older than version 0x20 the PSD will not use them and therefore will not run in Symmetric Mode. These APICs have problems handling EOI. A workaround may be implemented in the future. The resume code for interrupts has been cleaned up. The shutdown code was cleaned up. The AcpiDaemon.exe has been reorganized to be more flexible with different types of functions such as PowerMan. The format of acpid.cfg has changed. See the new acpid.cfg.sample for the new format. Powerman is now integrated into acpidaemon.exe. You can still run powerman.exe if you do not run acpidaemon.exe, but they will not both run at the same time. The throttling algorithm has been improved. PowerMan configuration is now integrated into acpid.cfg. The standalone powerman.exe is not supported anymore. A new powerdlg.exe is available to talk to the new integrated powerman and write the new config format. Old versions of powerdlg.exe will not work with the new integrated powerman and may cause problems if used. The vpic.sys driver has been removed from the ACPI package. It may or may not be put back in the future. Do not use any version of vpic.sys from previous ACPI distributions. You may use the IBM version of this driver. 3.19.02 - David Azarewicz ------------------------- The interrupt handling and setup code in the PSD has been mostly rewritten. It works differently than previous versions of ACPI.PSD. The documentation has been updated to reflect the differences. Read it. The most significant change is that the PSD now starts the system in Symmetric Mode (formerly known as APIC mode). This means that all drivers can be assigned one interrupt that they can use forever. The nightmare of switching interrupts part way through the bootup is now not necessary. Drivers also do not need to be "ACPI aware" in that they do not need to call the PSD to find their interrupt. Because of the changes, this PSD is more efficient and may cause your system to operate faster. This may expose existing problems in other places. This does NOT mean that the PSD is broken! These problems in other places were already there and a faster system can uncover them or make them occur more often. For example, there is a known existing problem starting the pmshell due to a problem in doscall1.dll. The doscall1.dll problem can cause a Trap D, a Trap E, or a hang. This problem in doscall1.dll has always been there and is not related to anything in the PSD. It can occur randomly when booting a multiprocessor system. Increased system speed makes the problem more likely. Single processor systems appear to not be affected. Again, this problem is NOT a problem with the PSD. A solution to the doscall1.dll problem is being investigated separately. 3.19 and previous - eCo Software -------------------------------- The ACPI project was originally created and maintained from 2005 through 2009 by eCo Software.
