/** |
|
* struct ps3_bmp - a per cpu irq status and mask bitmap structure |
|
* @status: 256 bit status bitmap indexed by plug |
|
* @unused_1: Alignment |
|
* @mask: 256 bit mask bitmap indexed by plug |
|
* @unused_2: Alignment |
|
* |
|
* The HV maintains per SMT thread mappings of HV outlet to HV plug on |
|
* behalf of the guest. These mappings are implemented as 256 bit guest |
|
* supplied bitmaps indexed by plug number. The addresses of the bitmaps |
|
* are registered with the HV through lv1_configure_irq_state_bitmap(). |
|
* The HV requires that the 512 bits of status + mask not cross a page |
|
* boundary. PS3_BMP_MINALIGN is used to define this minimal 64 byte |
|
* alignment. |
|
* |
|
* The HV supports 256 plugs per thread, assigned as {0..255}, for a total |
|
* of 512 plugs supported on a processor. To simplify the logic this |
|
* implementation equates HV plug value to Linux virq value, constrains each |
|
* interrupt to have a system wide unique plug number, and limits the range |
|
* of the plug values to map into the first dword of the bitmaps. This |
|
* gives a usable range of plug values of {NR_IRQS_LEGACY..63}. Note |
|
* that there is no constraint on how many in this set an individual thread |
|
* can acquire. |
|
* |
|
* The mask is declared as unsigned long so we can use set/clear_bit on it. |
