Rnumber in ddi_regs_map_setup

Hi All,
I have a doubt on ddi_regs_map_setup fn call.
In the ddi_regs_map_setup the explanation for
rnumber is.
rnumber - Index number to the register address
space set.
How do we know whether the address space is I/O
or memory address space.
Is there any documentation on this rnumber it would
be of great help.
Regards,
Sumanth

Hi,
Check the following document:
"Writinng Solaris PCI Device Drivers" (page: 9)
at:
http://soldc.sun.com/developer/support/driver/docs/docs.html
which explains this in detail.

Ddi_regs_map_setup rnumber parameter

Can anyone expand on the explanation of rnumber in the
man page for ddi_regs_map_setup ? I am confused about
what value I need to supply. What is the register address
space set it refers to?
rnumber Index number to the register address space set.

The register information can be found from the reg property (see "prtconf -vp"). The format of this property is bus dependant and can be found in the man pages for isa(4), pci(4) and sbus(4).
Hope this helps.

Need guidance on using ddi_regs_map_setup solaris system call

Hi all,
Am a beginner in using Sun Solaris.
I am working on porting our source code from linux to solaris.
In Linux we are using inb/outb to read/write to keyboard data port(0x60) .
I know that there is an equivalent system call for inb/outb in solaris. But in man page(of sun os) it is mentioned that inb/ outb are obsolete. It was mentioned that we can use ddi_get8/ddi_put8 functions respectively.
ddi_get8 call requires ddi_acc_handle_t as a parameter which we can get it from ddi_regs_map_setup system call.
Syntax for this call is:
int ddi_regs_map_setup(dev_info_t *dip, uint_t rnumber,
caddr_t *addrp, offset_t offset, offset_t len,
ddi_device_acc_attr_t accattrp, ddi_acc_handle_t handlep);
Please let me know where does the 0x60 port number fits in the above system call and what does these parameters rnumber, offset, len corresponds to ?

Hi,
The Fault_PC 0x13575e8 tells you exactly where you
die. I assume you have used this in mdb on
the core file to find you are dying in the ddi_get8 call?
Are you checking return value of ddi_regs_map_setup?
Are you sure the register you are accessing is in register set 1?
Are there other places prior to the panic where
the ddi_get/ddi_put routines work correctly? A bus error
here generally means the location you are trying to access
does not exist on the device. (It could also be alignment,
but not with ddi_get8). The address
looks like 1fe.02001400, which looks like a possibly
valid address in I/O space.
I would print the value of wc->ioaddr to make sure
it is a valid virtual address.
Hi,
I'm in the middle of porting a device driver for a
PCI card from linux to solaris (it's wcfxo from
zaptel - part of asterisk).

ddi_regs_map_setup(wc->dip, 1, &wc->ioaddr, 0, 255,
&dev_attr,
&dev_attr, &wc->devhandle);I've tested the same card in a linux x86 box, and it
works fine, so I'm happy it's not a hardware
problem.
Any suggestions on what might be causing this?

Ddi_regs_map_setup fails

Hi all,
I have a device as for which I am trying to do a IO_MAPPED driver.
I am doing on my Ultra60 the following code:
size_t memory_size;
for( i=0; i<6; i++ )
ddi_dev_regsize(dip, i, &memory_size);
result = ddi_regs_map_setup(dip, i,
&drx->ioBase.address, 0, mem_size,
&devAttr, &drx->ioBase.handle);
printf("ddi_regs_map_setup(,%d,,,0x%X,,)
returned %d\n", i, mem_size, result );
if (result == DDI_SUCCESS)
ddi_regs_map_free(&drx->ioBase.handle);
On the Ultra60, the reg sizes are:
ddi_regs_map_setup(,0,,,0x0,,) returned 0
ddi_regs_map_setup(,1,,,0x100,,) returned 0
ddi_regs_map_setup(,2,,,0x1000,,) returned -7
ddi_regs_map_setup(,3,,,0x100,,) returned 0
ddi_regs_map_setup(,4,,,0x1000,,) returned -7
ddi_regs_map_setup(,5,,,0x0,,) returned -6
My question is, if I want to map more than 0x200 sized device memory, how do i do it? Because rnumber 1 & 3 will allow me to map registers of sizes 0x100 each only!
or am i understanding this wrong?
any help appreciated!
Thanks!

each of the registers covers an area of pci bus address space supplied by the card
why don't you print out the return value from ddi_dev_regsize() as that will tell you
how much space the card is exporting for each of the registers .

Ddi_regs_map_setup fails in solaris 11

Hi
I have a driver (parent=isa) in x86 that ioremaps (ddi_regs_map_setup) a physical address range between 0xE0000 and 0xF0000.
This is a device memory mapped region.
The ddi_regs_map_setup was successful in solaris 10 (32 bit and 64 bit) but fails in solaris 11.
The warning message
WARNING: isa_apply_range: Out of range base <base> size <size>
The ddi_regs_map_setup goes through for the same region if driver made as parent=pci instead of parent=isa.
Would be helpful if someone could point out why this happens in solaris 11?
cheers

Specific code for device- kernel mem mapping

I would like to see an example of device memory to kernel memory mapping code.
Yes, there is a section in WDD about memory mapping, but it is geared towards device<->USER-memory mapping.
or kernel<-> user-memory mapping.
Could someone please point me towards a specific example of doing device<->kernelspace memory mapping?

I would like to see an example of device memory to
kernel memory mapping code.[CUT]
Could someone please point me towards a specific
example of doing device<->kernelspace memory
mapping?look at the ddi_regs_map_setup(9F) man page. Devices have register
blocks. Assuming this is a PCI card, the pci config registers will be
rnumber=0, device specific registers are usually rnumber=1,
and some device have more after that (i.e. if they have on board memory,
it could be mapped in rnumber=1 or rnumber=2 or even have
a way to access it through config space.

Hi,
to be a bit more specific:
you shouldnt have to do any direct mapping of addresses yourself. both the register space, AND the io space of a PCI card should be accessible through
ddi_regs_map_setup.
If you download my PCIbase.tar from
http://www.bolthole.com/solaris/#drivers
it will give you a helper script called printregs,
which will show you which register set gets mapped to which address space.
It's always the same,for the same card. So if printregs says that the iospace memory you care about is in register set 3, then you can pretty much always use
ddi_regs_map_setup(dip, 3, ....) to map in that space.

How to solve the "Method invocation failed" error in script?

Also I have found the explanation on this error on this
link but it seems this is not the case. Can you help to solve this?
Thanks!

You are importing a CSV file which implies that you are creating an object (pscustomobject) and each item in that object is represented by $line. The issue is that this $line has multiple properties (for each column of the CSV) that you need to decide
on which one to split:
$c = $line.propertyname.split(",")
I'm not sure, but it seems that if you are trying to split by a comma, then maybe you are assuming that you did something similar to a
get-content on the file in which the original approach that you have done would work.

Help in compiling/linking a DEVICE DRIVER in SOLARIS10 x86

FRM-40831 : Truncation occured: value too long for filed MAST_EMP_NAME

Hi
I'm using Forms 5 and getting following error.
FRM-40831 : Truncation occured: value too long for filed MAST_EMP_NAME.
When i checked in the column Mast_emp_name, all the values are with in the limit.
Table contains some 9 lacs record.
Please help me. this is very urgent

check the maximum length - property of all those 5 columns in your form. They have to be as long as in the database. Except number. They have to be 1 char longer than in the db.
Forms-Online-Help says:
This property can potentially limit the amount of data that an item is allowed to contain internally (in the Forms server) when it's in native format. It can also potentially limit the number of character (or bytes) displayed or entered by the end user. That is, it can specify a data limit and/or a user interface (UI) limit. The exact effect depends upon several factors, including the item's Data type, Data Length Semantics, and Format Mask properties. For a character item (datatypes CHAR, ALPHA, LONG), the Maximum Length property specifies a data limit. The property value specifies either the maximum number of bytes or else the maximum number of characters, depending upon the value of the Data Length Semantics property. Within a group of character mirror items, the Maximum Length property is always taken from the master mirror item. A compiler (generator) warning is issued if a non-zero non-default value is specified in a subordinate mirror item. If a character item has no format mask (the Format Mask property is null), then the Maximum Length property (taken from the master mirror item) also specifies a UI limit. When the Forms server is using the UTF8 character set , this UI limit has the same semantics (byte versus character) as the data limit. When the Forms server is using a multi-byte character set other than UTF8, and the Data Length Semantics property specifies byte semantics, Forms cannot prevent the end user from typing in too many bytes. Instead, it uses character semantics for the UI limit. In such a case, the end user is allowed to type in too many bytes. When the end user attempts to navigate out of the current validation unit, one of two things will happen. If the application property FLAG_USER_VALUE_TOO_LONG is set, an error will be flagged and the excess characters on the right will be selected. If this application property is not set, the excess characters will be quietly truncated, and the navigation will succeed. If a character item has a format mask, then the item's UI limit is derived from the format mask. This limit is always a character limit. For a number item (datatypes NUMBER, INT, MONEY, RNUMBER, RINT, RMONEY), the Maximum Length property specifies a user interface limit. This limit is always a character limit. There is no data limit. The data item can always internally hold up to 23 bytes (which is the maximum size of an Oracle number in native format), regardless of the value of the Maximum Length property. For a date or time item (datatypes DATETIME, DATE, TIME, JDATE, EDATE), the Maximum Length property specified in Forms Builder has almost no effect (See the Query Length property for a discussion of the only effect). As with "number" items, there is no data limit. For DATE and DATETIME items, the internal value is 7 bytes long, and for TIME, JDATE and EDATE items, the internal value is 4 bytes long . The user interface limit is derived from the format mask. This limit is always a character limit which is what is returned by GET_ITEM_PROPERTY(item, MAX_LENGTH).

Leading Zeroes are lost when convert from string to int

What I'm trying to do is simple yet the solution has seemed difficult to find.
I have a system that requires 4 digit numbers as "requisitionNo". The system uses JSPs and accepts the 4 digit number that the user inputs (fyi - duplicate handling is already managed). The input number (rNumber) is of STRING type and in the action (using struts) is converted to an int:
int requisitionNo = Integer.parseInt(rNumber);At that very line the issue is that when the user inputs a number with leading zeros such as: "0001" the 3 leading zeros are chopped off in the INT conversion. The application validation kicks in and says: "A 4 digit number is required" which is by design. The work around has been that the user has been putting in number that start with 9's or something like that, but this isn't how the system was intended to be used.
How do I keep the leading zeroes from being lost instead of saving a number "1" to the database how do I keep it saving "0001" to the database? Would I just change everything to STRING on down to the database? or is there another number type that I can be using that will not chop off the leading zeroes? Please provide short code references or examples to be more helpful.

Yeah, I have to agree here that leading zeroes make no sense. I figured that out when I started to look into this problem. The only requirement that exists is that the user wants it to be a 4 digit number due to some other requirement they have themselves.
So what I'm gathering from what I've read in the responses thus far is that I should change the validation a bit to look at the STRING for the 4 required digits (which are really 4 characters; maybe I should add CLIENT side numeric validation; currently its doing server side numeric/integer validation; or maybe change up the server side validation instead???) and if they are ALL GOOD then let the application save the int type as it wants to. IE: Let it save "0001" as just "1" and when I come back to DISPLAY this saved number to the user I should append the string of "000" in front of the 1 for display purposes only? Am I understanding everyone correctly?
