$Date: 15 May 1996 16:29:52 $
$Author: RWolff $
$Log: S:/source/wnt/ms11/miniport/archive/atimp.c_v $
*
* Rev 1.43 15 May 1996 16:29:52 RWolff
* Added workaround for Alpha hang on PCI bus greater than 0, now reports
* failure of mode set on Mach 64.
*
* Rev 1.42 01 May 1996 14:07:52 RWolff
* Calls new routine DenseOnAlpha() to determine dense space support rather
* than assuming all PCI cards support dense space.
*
* Rev 1.41 23 Apr 1996 17:16:38 RWolff
* Now reports 1M cards with SDRAM (needs special alignment in display
* driver), separated "internal DAC cursor double buffering needed"
* from "this is a CT".
*
* Rev 1.40 15 Mar 1996 16:27:08 RWolff
* IOCTL_VIDEO_FREE_PUBLIC_ACCESS_RANGES now only frees the I/O mapped
* registers in NT 4.0 and above. This is because the mapped values for
* the permanent and test screens use the same virtual address, and
* in 3.51 VideoPortUnmapMemory() refuses to unmap them.
*
* Rev 1.39 12 Mar 1996 17:41:50 RWolff
* Made IOCTL_VIDEO_FREE_PUBLIC_ACCESS_RANGES work under new source
* stream display driver, removed debug print statements from ATIMPResetHw()
* since this routine can't call pageable routines and debug print
* statements are pageable.
*
* Rev 1.38 29 Jan 1996 16:53:30 RWolff
* Now uses VideoPortInt10() rather than no-BIOS code on PPC, removed
* dead code.
*
* Rev 1.37 23 Jan 1996 11:41:10 RWolff
* Eliminated level 3 warnings, added debug print statements.
*
* Rev 1.36 22 Dec 1995 14:51:42 RWolff
* Added support for Mach 64 GT internal DAC, switched to TARGET_BUILD
* to identify the NT version for which the driver is being built.
*
* Rev 1.35 23 Nov 1995 11:24:40 RWolff
* Added multihead support.
*
* Rev 1.34 17 Nov 1995 13:41:02 RWolff
* Temporary fallback until problem with VideoPortGetBaseAddress() is
* resolved. This should have gone in as branch revision 1.33.1.0, but
* the @#$%^&* configuration doesn't allow branches.
*
* Rev 1.33 27 Oct 1995 14:20:06 RWolff
* Fixes to bring up NT 3.51 on PPC, no longer makes mapped LFB part of
* hardware device extension.
*
* Rev 1.32 08 Sep 1995 16:36:04 RWolff
* Added support for AT&T 408 DAC (STG1703 equivalent).
*
* Rev 1.31 28 Aug 1995 16:37:36 RWolff
* No longer restores memory size on x86 boxes in ATIMPResetHw(). This
* is a fix for EPR 7839 - the restoration is not necessary on x86
* machines, but on some non-x86 boxes the memory size is not restored
* on a warm boot, so we must do it to allow the use of modes needing
* more than 1M after booting out of a 4BPP mode.
*
* Rev 1.30 24 Aug 1995 15:39:42 RWolff
* Changed detection of block I/O cards to match Microsoft's standard for
* plug-and-play, now reports CT and VT ASICs to the display driver.
*
* Rev 1.29 03 Aug 1995 16:22:42 RWOLFF
* Reverted to old bus ordering (PCI last) for non-Alpha machines under
* NT 3.5. Using the new ordering (PCI first) on an x86 under 3.5
* resulted in the display applet rejecting attempts to test 16 and 24 BPP
* on a Mach 32 (PCI or ISA) in a PCI machine.
*
* Rev 1.28 02 Jun 1995 14:19:14 RWOLFF
* Rearranged bus test order to put PCI first, added CT internal to
* DACs supported in no-BIOS version.
*
* Rev 1.27 31 Mar 1995 11:55:18 RWOLFF
* Changed from all-or-nothing debug print statements to thresholds
* depending on importance of the message.
*
* Rev 1.26 08 Mar 1995 11:33:18 ASHANMUG
* The pitch in 24bpp should be the pitch in engine pixels and not true pixels
*
* Rev 1.25 27 Feb 1995 17:51:50 RWOLFF
* Now reports (Mach 64 only) whether I/O space is packed (relocatable)
* or not, reports number of lines of offscreen memory for 4BPP as if
* the card has 1M of video memory, since we set the card to 1M for
* this depth.
*
* Rev 1.24 24 Feb 1995 12:24:40 RWOLFF
* Now adds text banding to the ATIModeInformation->ModeFlags bits
* that are filled in.
*
* Rev 1.23 20 Feb 1995 18:03:30 RWOLFF
* Reporting of screen tearing on 2M boundary is now DAC-independant, added
* 1600x1200 16BPP to modes which experience this tearing.
*
* Rev 1.22 03 Feb 1995 15:13:50 RWOLFF
* Added packets to support DCI.
*
* Rev 1.21 30 Jan 1995 12:16:24 RWOLFF
* Made definition of IBM DAC special cursor flag consistent with
* similar flag for TVP DAC.
*
* Rev 1.20 18 Jan 1995 15:38:46 RWOLFF
* Now looks for Mach64 before looking for our older accelerators, Chrontel
* DAC is now supported as a separate type rather than being lumped in
* with STG1702.
*
* Rev 1.19 11 Jan 1995 13:54:00 RWOLFF
* ATIMPResetHw() now restores the memory size on Mach64 cards. This is
* a fix for a problem that showed up on the DEC Alpha, but may affect
* other platforms as well. In 4BPP modes, we must tell the card that it
* has only 1M of memory, but on a warm boot, the x86 emulation did not
* re-initialize the memory size, so until the next cold boot, only modes
* available in 1M were listed.
*
* Rev 1.18 04 Jan 1995 11:59:28 RWOLFF
* ATIMPFindAdapter() will only detect ATI cards on the first invocation,
* to avoid the same card being detected once per bus and causing problems
* when Windows NT thinks it's multiple cards.
*
* Rev 1.17 23 Dec 1994 10:48:10 ASHANMUG
* ALPHA/Chrontel-DAC
*
* Rev 1.16 18 Nov 1994 11:36:52 RWOLFF
* Now checks for PCI bus, cleaned up temporary debug print statements,
* fixed non-x86 Mach 64 handling, added support for Power PC and
* STG1703 DAC.
*
* Rev 1.15 31 Aug 1994 16:14:00 RWOLFF
* IOCTL_VIDEO_ATI_GET_VERSION packet now reports TVP3026 DAC (different
* cursor handling needed in display driver),
* IOCTL_VIDEO_ATI_GET_MODE_INFORMATION now reports 1152x864 24BPP as
* having screen tearing at end of first 2M bank.
*
* Rev 1.14 22 Jul 1994 17:47:50 RWOLFF
* Merged with Richard's non-x86 code stream.
*
* Rev 1.13 20 Jul 1994 13:04:06 RWOLFF
* Changes required to support multiple I/O base addresses for Mach 64
* accelerator registers, ATIMPInitialize() now leaves the adapter in
* a state where an INT 10 can switch it to a VGA mode (fix for
* showstopper bug on Landtrain machines), calls new routine
* FillInRegistry() so the video applet can get information about
* the graphics card.
*
* Rev 1.12 30 Jun 1994 18:11:36 RWOLFF
* Changes to allow the new method of checking for aperture conflict.
*
* Rev 1.11 15 Jun 1994 11:04:24 RWOLFF
* In IOCTL_VIDEO_ATI_GET_VERSION, now only sets
* RequestPacket->StatusBlock->Information if the buffer is big enough.
*
* Rev 1.10 20 May 1994 19:18:00 RWOLFF
* IOCTL_VIDEO_ATI_GET_VERSION old format packet now returns the highest
* pixel depth for a given resolution even if it isn't the last mode
* table for the resolution.
*
* Rev 1.9 20 May 1994 13:57:40 RWOLFF
* Ajith's change: now saves in the query structure the bus type reported by NT.
*
* Rev 1.8 12 May 1994 11:04:24 RWOLFF
* Now forces OEM handling on DEC ALPHA machines.
*
* Rev 1.7 04 May 1994 19:25:40 RWOLFF
* Fixes for hanging and corrupting screen when display applet run.
*
* Rev 1.6 28 Apr 1994 10:59:56 RWOLFF
* Moved mode-independent bug/feature flags to IOCTL_VIDEO_ATI_GET_VERSION
* packet from IOCTL_VIDEO_ATI_GET_MODE_INFORMATION packet.
*
* Rev 1.5 27 Apr 1994 13:54:42 RWOLFF
* IOCTL_VIDEO_ATI_GET_MODE_INFORMATION packet now reports whether MIO bug
* is present on Mach 32 cards.
*
* Rev 1.4 31 Mar 1994 15:05:00 RWOLFF
* Added DPMS support, brought ATIMPResetHw() up to latest specs, added
* debugging code.
*
* Rev 1.3 14 Mar 1994 16:32:20 RWOLFF
* Added ATIMPResetHw() function, fix for 2M boundary tearing, replaced
* VCS logfile comments that were omitted in an earlier checkin.
*
* Rev 1.2 03 Mar 1994 12:36:56 ASHANMUG
* Make pageable
*
* Rev 1.1 07 Feb 1994 13:56:18 RWOLFF
* Added alloc_text() pragmas to allow miniport to be swapped out when
* not needed, removed LookForSubstitute() since miniport is no longer
* supposed to check whether mode has been substituted, no longer logs
* a message when the miniport aborts due to no ATI card being found,
* removed unused routine ATIMPQueryPointerCapabilities().
*
* Rev 1.0 31 Jan 1994 10:52:34 RWOLFF
* Initial revision.
Rev 1.6 14 Jan 1994 15:14:08 RWOLFF
Removed commented-out code, packet announcements now all controlled by
DEBUG_SWITCH, device reset for old cards now done by a single call,
new format for IOCTL_VIDEO_ATI_GET_VERSION packet, reports block write
capability in IOCTL_VIDEO_ATI_GET_MODE_INFORMATION packet, added
1600x1200 support.
Rev 1.5 30 Nov 1993 18:10:04 RWOLFF
Moved query of card capabilities (once type of card is known) from
ATIMPFindAdapter() to ATIMPInitialize() because query for Mach 64 needs
to use VideoPortInt10(), which can't be used in ATIMPFindAdapter().
Rev 1.4 05 Nov 1993 13:22:12 RWOLFF
Added initial Mach64 code (currently inactive).
Rev 1.3 08 Oct 1993 11:00:24 RWOLFF
Removed code specific to a particular family of ATI accelerators.
Rev 1.2 24 Sep 1993 11:49:46 RWOLFF
Removed cursor-specific IOCTLs (handled in display driver), now selects
24BPP colour order best suited to the DAC being used instead of forcing
BGR.
Rev 1.1 03 Sep 1993 14:20:46 RWOLFF
Partway through CX isolation.
Rev 1.0 16 Aug 1993 13:27:50 Robert_Wolff
Initial revision.
Rev 1.23 06 Jul 1993 15:46:14 RWOLFF
Got rid of mach32_split_fixup special handling. This code was to support
a non-production hardware combination.
Rev 1.22 10 Jun 1993 15:58:32 RWOLFF
Reading from registry now uses a static buffer rather than a dynamically
allocated one (originated by Andre Vachon at Microsoft).
Rev 1.21 07 Jun 1993 11:43:16 BRADES
Rev 6 split transfer fixup.
Rev 1.19 18 May 1993 14:04:00 RWOLFF
Removed reference to obsolete header TTY.H, calls to wait_for_idle()
no longer pass hardware device extension, since it's a global variable.
Rev 1.18 12 May 1993 16:30:36 RWOLFF
Now writes error messages to event log rather than blue screen,
initializes "special handling" variables determined from BIOS
to default values on cards with no BIOS. This revision contains
code for experimental far call support, but it's "#if 0"ed out.
Rev 1.17 10 May 1993 16:35:12 RWOLFF
LookForSubstitute() now recognizes all cases of colour depth not
supported by the DAC, unusable linear frame buffer now falls back
to LFB disabled operation rather than aborting the miniport, removed
unused variables and unnecessary passing of hardware device extension
as a parameter.
Rev 1.16 30 Apr 1993 17:58:50 BRADES
ATIMP startio assign QueryPtr once at start of function.
uses aVideoAddress virtual table for IO port addresses.
Rev 1.15 30 Apr 1993 16:33:42 RWOLFF
Updated to use NT build 438 initialization data structure.
Registry read buffer is now dynamically allocated to fit data requested
rather than being a fixed "hope it's big enough" size.
Rev 1.14 21 Apr 1993 17:22:06 RWOLFF
Now uses AMACH.H instead of 68800.H/68801.H.
Accelerator detection now checks only for functionality, not our BIOS
signature string which may not be present in OEM versions. Query
structure now indicates whether extended BIOS functions and/or
EEPROM are present. Added ability to switch between graphics and
text modes using absolute far calls in BIOS. Removed handling
of obsolete DriverOverride registry field.
Rev 1.13 14 Apr 1993 18:30:22 RWOLFF
24BPP is now done as BGR (supported by both TI and Brooktree DACs)
rather than RGB (only supported by TI DACs).
Rev 1.12 08 Apr 1993 16:53:18 RWOLFF
Revision level as checked in at Microsoft.
Rev 1.9 25 Mar 1993 11:10:38 RWOLFF
Cleaned up compile warnings, now returns failure if no EEPROM is present.
Rev 1.8 16 Mar 1993 17:15:16 BRADES
get_cursor uses screen_pitch instead of x_size.
Rev 1.7 16 Mar 1993 17:04:58 BRADES
Change ATI video to graphics message
Rev 1.6 15 Mar 1993 22:20:30 BRADES
use m_screen_pitch for the # pixels per display lines
Rev 1.5 08 Mar 1993 19:23:44 BRADES
update memory sizing to 256 increments, clean code.
Rev 1.4 10 Feb 1993 13:01:28 Robert_Wolff
IOCTL_VIDEO_MAP_VIDEO_MEMORY no longer assumes frame buffer length
is equal to video memory size (linear aperture present). It can now
accept 64k (uses VGA aperture) and 0 (no aperture available).
Rev 1.3 06 Feb 1993 12:55:52 Robert_Wolff
Now sets VIDEO_MODE_INFORMATION.ScreenStride to bytes per line (as listed
in the documentation). In the October beta, it had to be pixels per line.
Rev 1.2 05 Feb 1993 22:12:36 Robert_Wolff
Adjusted MessageDelay() to compensate for short_delay() no longer being
optimized out of existence.
Rev 1.1 05 Feb 1993 16:15:28 Robert_Wolff
Made it compatible with the new DDK, registry calls now use VideoPort
functions rather than RTL functions. This version will work with the
framebuffer driver.
Rev 1.0 02 Feb 1993 13:36:50 Robert_Wolff
Initial revision.
Rev 1.2 26 Jan 1993 10:28:30 Robert_Wolff
Now fills in Number<colour>Bits fields in VIDEO_MODE_INFORMATION structure.
Rev 1.1 25 Jan 1993 13:31:52 Robert_Wolff
Re-enabled forcing of shared VGA/accelerator memory for Mach 32
cards with no aperture enabled.
Rev 1.0 22 Jan 1993 16:44:42 Robert_Wolff
Initial revision.
Rev 1.26 21 Jan 1993 17:59:24 Robert_Wolff
Eliminated multiple definition link warnings, updated comments
in LookForSubstitute().
Rev 1.25 20 Jan 1993 17:47:48 Robert_Wolff
Now checks optional DriverOverride field in registry, and forces
use of appropriate (engine, framebuffer, or VGAWonder) driver
if the field is present and nonzero. If field is missing or zero,
former behaviour is used.
IOCTL_VIDEO_ATI_GET_VERSION packet now also returns the maximum
pixel depth available at each resolution.
Added mode substitution case for 16 BPP selected when using the
engine-only (fixed 8 BPP colour depth) driver.
Rev 1.24 15 Jan 1993 15:12:26 Robert_Wolff
Added IOCTL_VIDEO_ATI_GET_VERSION packet in ATIMPStartIO() to
return version number of the miniport.
Rev 1.23 14 Jan 1993 17:49:40 Robert_Wolff
Removed reference to blank screen in message printed before query
structure filled in, moved printing of this message and the "Done."
terminator so all checking for video cards is between them.
Rev 1.22 14 Jan 1993 10:37:28 Robert_Wolff
Re-inserted "fail if VGAWonder but no ATI accelerator" check due
to lack of VGAWONDER .DLL file in late January driver package.
Rev 1.21 13 Jan 1993 13:31:04 Robert_Wolff
Added support for the Corsair and other machines which don't store
their aperture location in the EEPROM, single miniport now handles
VGAWonder in addition to accelerators.
Rev 1.20 07 Jan 1993 18:20:34 Robert_Wolff
Now checks to see if aperture is configured but unusable, and
forces the use of the engine-only driver if this is the case.
Added message to let users know that the black screen during
EEPROM read is normal.
Rev 1.19 06 Jan 1993 11:04:36 Robert_Wolff
BIOS locations C0000-DFFFF now mapped as one block, cleaned up warnings.
Rev 1.18 04 Jan 1993 14:39:50 Robert_Wolff
Added card type as a parameter to setmode().
Rev 1.17 24 Dec 1992 14:41:20 Chris_Brady
fixup warnings
Rev 1.16 15 Dec 1992 13:34:46 Robert_Wolff
Writing of MEM_CFG when forcing 4M aperture now preserves all but
the aperture size bits. This allows operation on Corsair as well
as standard versions of the Mach 32 card.
Rev 1.15 11 Dec 1992 14:45:44 Robert_Wolff
Now forces the use of the FRAMEBUF driver if a 2M aperture is configured.
Rev 1.14 11 Dec 1992 09:47:34 Robert_Wolff
Now sets the "don't show the substitution message" flag no matter what
the status of the first call to LookForSubstitute() was (sub, no sub,
or error), rather than only when a substitution was made and the message
was displayed.
Rev 1.13 10 Dec 1992 14:24:16 Robert_Wolff
Shortened mode substitution messages in LookForSubstitute(), messages
are now displayed only on the first call to this routine, to avoid
delays in switching back to graphics mode from a full-screen DOS box.
Rev 1.12 09 Dec 1992 14:18:38 Robert_Wolff
Eliminated uninitialized pointer in IOCTL_VIDEO_SET_CURRENT_MODE
packet, moved initialization of QueryPtr and FirstMode pointers
to before the switch on packet type, rather than being in all
packets where the pointers are used. This should prevent similar
problems if other packets are changed to use the pointers, and
eliminates redundant code.
Rev 1.11 09 Dec 1992 10:35:04 Robert_Wolff
Added user-level "blue-screen" messages for fatal errors, checks BIOS
revision to catch Mach 8 cards that can't do 1280x1024, forces the
use of the engine-only driver if no aperture is configured, memory
boundary and hardware cursor stuff is now done only for Mach 32 cards
(since they're only available on Mach 32), sets split pixel mode for
Mach 8 in 1280x1024, added mode substitution message for Mach 8 when
registry is configured for 16 BPP or higher.
Rev 1.10 01 Dec 1992 17:00:18 Robert_Wolff
"I-beam" text insertion cursor no longer has left side filled with a
solid black block.
Rev 1.9 30 Nov 1992 17:34:38 Robert_Wolff
Now allows 1M aperture if configured video mode uses less than 1M
of video memory, prints message to user if Windows NT decides
to use a video mode other than the one configured in the registry.
Rev 1.8 27 Nov 1992 18:40:24 Chris_Brady
VGA Wonder detect looks for signature in a range.
Graphics Ultra Pro Microchannel version moved it.
Rev 1.7 25 Nov 1992 09:47:36 Robert_Wolff
Now tells GetCapMach32() to assume the VGA boundary is set to shared,
since we will set it to this value later, and we don't want to lose
access to modes which require some of the memory currently assigned
to the VGA. Added delay in IOCTL_VIDEO_SET_CURRENT_MODE case of
ATIMPStartIO() after calculating the hardware cursor offset. This delay
may not be needed, but I didn't want to remove it since this is the
source for the driver sent to QA and I wanted it to be rebuildable.
Rev 1.6 20 Nov 1992 16:04:30 Robert_Wolff
Now reads query information from Mach 8 cards instead of only
from Mach 32 cards. Mach 8 cards still cause ATIMPFindAdapter()
to return ERROR_INVALID_PARAMETER, since until we get an engine-only
driver, we can't use a card that doesn't support an aperture.
Rev 1.5 19 Nov 1992 09:53:36 GRACE
after setting a mode do a wait for idle to let the pixel clock settle before
using engine to draw.
Rev 1.4 17 Nov 1992 14:07:52 GRACE
changed framelength to reflect the size of memory on the board not the
aperture size.
In the StartIO section, only set up QueryPtr and FirstMode when necessary
Rev 1.3 12 Nov 1992 09:23:02 GRACE
removed the struct definition for DeviceExtension to a68.h
Not using DevInitATIMP, DevSetCursorShape, DevSetCursorPos or DevCursorOff.
DevCursorOff changed to a define that turns cursor off with an OUTP.
Also removed some excess junk that is left from the video program.
Rev 1.2 06 Nov 1992 19:12:48 Robert_Wolff
Fixed signed/unsigned bug in multiple calls to VideoPortInitialize().
Now requests access to I/O ports and ROM addresses used for VGA-style
EEPROM reads, and gets information about installed modes from the
Mach32 card.
NOTE: This is a checkpoint for further changes. Due to incompatibilities
between the old (hardcoded resolution) code in other modules and the
new (read from the card) code here, this revision will not produce a
working driver.
Rev 1.1 05 Nov 1992 12:02:18 Robert_Wolff
Now reads query structure and mode tables from the MACH32 card
rather than using hardcoded values for aperture size/location
and supported modes.
Rev 1.0 02 Nov 1992 20:47:58 Chris_Brady
Initial revision.

* The docs on VideoPortInitialize() say to return the smallest
* returned value if multiple calls are made (consistent with
* the NTSTATUS format where the 2 most significant bits are
* 00 for success, 01 for information, 10 for warning, and
* 11 for error, since the multiple calls would be for mutually

Routine Description:
This routine is the main execution entry point for the miniport driver.
It accepts a Video Request Packet, performs the request, and then
returns with the appropriate status.
Arguments:
HwDeviceExtension - Supplies the miniport driver's adapter storage. This
storage is initialized to zero before this call.
HwContext - Supplies the context value which was passed to
VideoPortInitialize().
ArgumentString - Suuplies a NYLL terminated ASCII string. This string
originates from the user.
ConfigInfo - Returns the configuration information structure which is
filled by the miniport driver . This structure is initialized with
any knwon configuration information (such as SystemIoBusNumber) by
the port driver. Where possible, drivers should have one set of
defaults which do not require any supplied configuration information.
Again - Indicates if the miniport driver wants the port driver to call
its VIDEO_HW_FIND_ADAPTER function again with a new device extension
and the same config info. This is used by the miniport drivers which
can search for several adapters on a bus.
Return Value:
This routine must return:
NO_ERROR - Indicates a host adapter was found and the
configuration information was successfully determined.
ERROR_INVALID_PARAMETER - Indicates a host adapter was found but there was an
error obtaining the configuration information. If possible an error
should be logged.
ERROR_INVALID_PARAMETER - Indicates the supplied configuration was invalid.
ERROR_DEV_NOT_EXIST - Indicates no host adapter was found for the
supplied configuration information.

* we must load the VGA text font.
*
* On the Mach 64, some non-x86 machines (first noticed on the
* DEC Alpha) don't do the warm boot BIOS re-initialization that
* is done on the x86. Part of this re-initialization sets the
* memory size register to the correct amount of memory, which
* must be done if we were in a 4BPP mode (in 4BPP, we must force
* the memory size to 1M). To avoid locking out modes requiring
* over 1M (at least until the next cold boot) on these machines,
* we must restore the memory size to the correct value. Since this
* has the side effect of generating black vertical bands as a
* transient (due to interleaving of memory banks on 2M and higher
* configurations), only do this on non-x86 machines, since the
* BIOS will take care of it (without the visible side effect)
* on x86 platforms.
*
* Since this routine, and all routines it calls, must be
* nonpageable (in case the reason it is called is because
* there is a fatal error in the paging mechanism), and
* VideoDebugPrint() is pageable, we must not call VideoDebugPrint()
* from this routine. Temporary additions for testing are OK,
