Subject: [PATCH] hw/nvme: fix number of PIDs for FDP RUH update
|
||
|
|
|
||
|
|
The number of PIDs is in the upper 16 bits of cdw10. So we need to
|
||
|
|
right-shift by 16 bits instead of only a single bit.
|
||
|
|
|
||
|
|
Fixes: 73064edfb864 ("hw/nvme: flexible data placement emulation")
|
||
|
|
|
||
|
