Subject: [PATCH] kern/ieee1275/init: Extended support in Vec5
|
|
MIME-Version: 1.0

|
|
|
This patch enables multiple options in Vec5 which are required and
|
|
solves the boot issues seen on some machines which are looking for
|
|
these specific options.
|
|
|
|
1. LPAR: Client program supports logical partitioning and
|
|
associated hcall()s.
|
|
2. SPLPAR: Client program supports the Shared
|
|
Processor LPAR Option.
|
|
3. DYN_RCON_MEM: Client program supports the
|
|
“ibm,dynamic-reconfiguration-memory” property and it may be
|
|
presented in the device tree.
|
|
4. LARGE_PAGES: Client supports pages larger than 4 KB.
|
|
5. DONATE_DCPU_CLS: Client supports donating dedicated processor cycles.
|
|
6. PCI_EXP: Client supports PCI Express implementations
|
|
utilizing Message Signaled Interrupts (MSIs).
|
|
|
|
7. CMOC: Enables the Cooperative Memory Over-commitment Option.
|
|
8. EXT_CMO: Enables the Extended Cooperative Memory Over-commit Option.
|
|
|
|
9. ASSOC_REF: Enables “ibm,associativity” and
|
|
“ibm,associativity-reference-points” properties.
|
|
10. AFFINITY: Enables Platform Resource Reassignment Notification.
|
|
11. NUMA: Supports NUMA Distance Lookup Table Option.
|
|
|
|
12. HOTPLUG_INTRPT: Supports Hotplug Interrupts.
|
|
13. HPT_RESIZE: Enable Hash Page Table Resize Option.
|
|
|
|
14. MAX_CPU: Defines maximum number of CPUs supported.
|
|
|
|
15. PFO_HWRNG: Supports Random Number Generator.
|
|
16. PFO_HW_COMP: Supports Compression Engine.
|
|
17. PFO_ENCRYPT: Supports Encryption Engine.
|
|
|
|
18. SUB_PROCESSORS: Supports Sub-Processors.
|
|
|
|
19. DY_MEM_V2: Client program supports the “ibm,dynamic-memory-v2” property in the
|
|
“ibm,dynamic-reconfiguration-memory” node and it may be presented in the device tree.
|
|
20. DRC_INFO: Client program supports the “ibm,drc-info” property definition and it may be
|
|
presented in the device tree.
