Can I add you to the information about the program? About tab?
I do not understand.   ???



One more question. I check the flags by:
Codice: [Seleziona]
 Print data.flags[0]
    Print data.flags[1]
    Print data.flags[89]

But how to know what the flag corresponds to the flags
  • or flags [8]
I do not know it.



And yet how it should look SSE_SIZE

Print data.sse_size return me 0, in C return me 64
Yes, I confirm the problem !
Well, I studied the memory area of cpu_id_t structure. I suppose, that problem, is the usual difficulties for Gambas to manage the external structures.
In fact, if I change the number in this member:
Codice: [Seleziona]
uint8_t flags[CPU_FLAGS_MAX]
from 128 to 124 all works well, but 124 does not match the value of the constant CPU_FLAGS_MAX.
In fact it is declared in /usr/include/libcpuid/libcpuid_constants.h as follows:
  #define CPU_FLAGS_MAX      128

So, I ask you to change to:
Codice: [Seleziona]
flags[124] As Byte
and re-try the code.
Let me know !

....I know, it's absurd and indescribable, but already I told you:
In my experience, however, you might have trouble by reading from those Byte[nn] type array members.

A clean alternative is by using reserved memory area pointed by a Pointer variable.


in C:
Codice: [Seleziona]
printf("	\"SSE_SIZE\": \"%d bits (%s)\"\n", data.sse_size, data.detection_hints[CPU_HINT_SSE_SIZE_AUTH] ? "authoritative" : "non-authoritative");

...well, now our new code is:

Now the problem is with the flags of the CPU.
How to detect whether the instruction is served by processor.

Codice: [Seleziona]
	/**
* contain CPU flags. Used to test for features. See
* the \ref cpu_feature_t "CPU_FEATURE_*" macros below.
* @see Features
*/
uint8_t flags[CPU_FLAGS_MAX];

Codice: [Seleziona]
typedef enum {
CPU_FEATURE_FPU = 0, /*!< Floating point unit */
CPU_FEATURE_VME, /*!< Virtual mode extension */
CPU_FEATURE_DE, /*!< Debugging extension */
CPU_FEATURE_PSE, /*!< Page size extension */
CPU_FEATURE_TSC, /*!< Time-stamp counter */
CPU_FEATURE_MSR, /*!< Model-specific regsisters, RDMSR/WRMSR supported */
CPU_FEATURE_PAE, /*!< Physical address extension */
..............................................
NUM_CPU_FEATURES,
} cpu_feature_t;
Codice: [Seleziona]
/**
 * @brief Returns the short textual representation of a CPU flag
 * @param feature - the feature, whose textual representation is wanted.
 * @returns a constant string like "fpu", "tsc", "sse2", etc.
 * @note the names of the returned flags are compatible with those from
 *       /proc/cpuinfo in Linux, with the exception of `tm_amd'
 */
const char* cpu_feature_str(cpu_feature_t feature);
In C look like this:

Codice: [Seleziona]
	printf("					\"VALUE\": %s \n", data.flags[CPU_FEATURE_MMXEXT] ? "1 ," : "0 ,");

Or code from cpuid_tool:
Codice: [Seleziona]
for (i = 0; i < NUM_CPU_FEATURES; i++)
if (data.flags[i])
fprintf(fout, " %s", cpu_feature_str(i));
fprintf(fout, "\n");
Also, do not close this thread.

You should strive to write some code :violent: , otherwise you'll never learn!

In C look like this:

Codice: [Seleziona]
	printf("					\"VALUE\": %s \n", data.flags[CPU_FEATURE_MMXEXT] ? "1 ," : "0 ,");

If you want to use only this line and that enum value, you may set it like a Constant value. Then you can use IIf keyword:

Codice: [Seleziona]
Private Const CPU_FEATURE_MMXEXT As Integer = 55
.....
......

Print "   \"VALUE\":              "; IIf(data.flags[CPU_FEATURE_MMXEXT], "1 ,", "0 ,")

But if you want use all cpu_feature_t enumeration values, obviously in your Gambas code you'll have to set all the values of that enumeration !

Ok, i create some code to check flags.

First from you:
.......
For i = 84 To 211
      Print i - 84, Byte@(data + i)
Next
.......

And my code:
..............
For i = 0 To 127
     Print i, data.flags
Next
..............

In the code, where is declared and used "cpu_id_t" Structure, the bytes are shifted by 4 bytes behind.

For example, index 22 of the code with allocated memory area  =  index 18 of code with Structure !
It seems it looses the first 4 byte in the beginning.

I do not why, but I fear it is the Gambas problem to manage extern structture having Byte[ ] type members.   :-X


.....in my opinion, for more security you will have to use the reserved memory area, pointed by a Pointer variable.

So i must use Dim data As Pointer, not as cpu_id_t

And i must use:

Dim data As New cpu_id_t
and for flags
Dim data_flags As Pointer?

If we want to use allocated memory area, we have to identify the bytes where each member of that Structure begins.

Well, we have this tabula memoranda of indices:
Public Struct cpu_id_t
  vendor_str[16] As Byte                   '       0 -  15
  brand_str[64] As Byte                     '     16 -  79
  vendor As Integer                            '     80 -  83
  flags[128] As Byte                            '    84 - 211
  family As Integer                              '  212 - 215
  model As Integer                             '  216 - 219
  stepping As Integer                         '  220 - 223
  ext_family As Integer                      '  224 - 227
  ext_model As Integer                     '  228 - 231
  num_cores As Integer                    '  232 - 235
  num_logical_cpus As Integer       '  236 - 239
  total_logical_cpus As Integer       '  240 - 243
  l1_data_cache As Integer             '  244 - 247
  l1_instruction_cache As Integer  '  248 - 251
  l2_cache As Integer                       '  252 - 255
  l3_cache As Integer                       '  256 - 259
  l4_cache As Integer                       '  260 - 263
  l1_assoc As Integer                       '  264 - 267
  l2_assoc As Integer                       '  268 - 271
  l3_assoc As Integer                       '  272 - 275
  l4_assoc As Integer                       '  276 - 279
  l1_cacheline As Integer                '  280 - 283
  l2_cacheline As Integer                '  284 - 287
  l3_cacheline As Integer                '  288 - 291
  l4_cacheline As Integer                '  292 - 295
  cpu_codename[64] As Byte         '  296 - 359
  sse_size As Integer                       '  360 - 363
  detection_hints[16] As Byte         '  364 - 379
  sgx As Struct Cpu_sgx_t              '  380 - 431
End Struct


Total dimension: 432 byte

To extract the values you have to use the dereferencing Gambas functions: Byte@( ), Int@( ), etc.

Exemplum, we want to extract family member value. We know this member begins at byte index 212, and occupies 4 byte (from byte 212 to byte 215), because it's an Integer.
Well, we get its value in this way: we shift to the byte index 212, and we use the Pointer dereferencing function Int@( ):
Codice: [Seleziona]
Print int@(data + 212)

Pay attention:  :danger:
in our Gambas code, now, we no longer use the object cpu_id_t Structure !


If we want, we can use also Memory Stream resource , to read inside our reserved memory area.



and for flags
Dim data_flags As Pointer?
In C declaration of cpu_id_t Structure the flags member is a 1-byte values array.
So, each flags value occupies one byte.
The values of the array are arranged - linearly and simply - along the memory area of cpu_id_t Structure, for as many as 128 individual bytes.
So, in Gambas........   :)

Well, it's a possible way, but... mmmm... you have used cpu_identify( ) twice.
...we may call it as a kind of... " increased procedure ".   


So, I would use only a reseved memory area, pointed by a Pointer variable:

Currently, the libcpuid 16 library introduces a lot of changes, so the code for the Gambas language is no longer up to date.
I'm trying to figure out how to fix it. Below is the code I am working on.

I figured out what the problem is. Please vuott can you take a look at this and if you can direct me to a solution?

Sorry, but, to do the test, my system only allows me to have libcpuid version 15.
