VSH

VSH is the internal name used by Sony for the VShell aka VirtualShell. It then loads up the XMB you know. XrossMediaBar (XMB). This, is a userspace executable (vsh.self), loaded by lv2_kernel/sys_init_osd.

from here several other functions/syscalls to other modules are made, e.g. lv2 (SELF decryption), lv1 (Secure_RTC, Storage_Manager, Gelic_Device, BD_Drive) etc.

not much is documented (yet) about this module. Please fill in where possible.

Notification Window Textures

Notification Window Textures (inside dev_flash/vsh/resource/system_plugin.rco)

All the icons are 100x100 pixels size

• tex_notification_caution
• tex_notification_friend
• tex_notification_headset
• tex_notification_info
• tex_notification_keypad
• tex_notification_mediaserver
• tex_notification_music
• tex_notification_psbutton_insensitive
• tex_notification_settings
• tex_notification_trophy_bronze
• tex_notification_trophy_gold
• tex_notification_trophy_platinum
• tex_notification_trophy_silver

The other texture used by notification window is the frame of the notification window itself (called "tex_notification" with a size of 64x64 pixels), this frame is scalated in width automatically by XMB (to make the frame fit the width of the text that is displayed inside the window), and is posible to reskin the frame using a Theme

• Any texture from any plugin can be used actually. i.e.: tex_common_dialog. Would it be possible to create our own textures?
  • Sure, there is no security check over .RCO's (resource containers), what is not clear is if is posible to load a texture with a custom name from a .RCO with a custom name (e.g: tex_myicon from a file named: myresources.rco)... Initially .SPRX needs to be "indexed" by VSH to be available, and .RCO's are dependant of .SPRX... but in case of the resources is posible all are available --Sandungas (talk) 19:22, 20 May 2014 (EDT)

Display Buffers

VSH uses 2 of 8 available display buffers. Information about them can be aquired by vsh plugins using this code snippet: [[1]]
In FW 4.46 DEX the buffer info looks like this (for 1920x1080):

GCMBUFINFO 0
address: 0xdc80000
pitch: 0x2000
width: 0x780
height: 0x438

GCMBUFINFO 1
address: 0xe500000
pitch: 0x2000
width: 0x780
height: 0x438

Settings

VSH contains an array of structs which describes the xRegistry.sys. (More Information about its access Talk:VSH )

struct Setting_s
{
  int32_t index;
  const char* name;
  int32_t unk0;
  int8_t unk1;
  union
  {
     int32_t integer;
     const char* string;
  }default;
  int32_t type;
  int32_t unk2;
};

The first element of this array describes the password setting. Use this script to label all of the settings. link

.long 1                 # index
.long aSettingParen_4   # name # "/setting/parental/passwordNumber"
.long 1                 # unk0
.byte 1                 # unk1
.byte 0, 0, 0
.long a0000_1           # default # "0000"
.long 4                 # type
.long 0x28              # unk2
