| Thread-topic: | [PATCH][HVM] Fix 2 type mismatches in vlapic.h and hpet.c for 32-bit build Xen |
For 32-bit build of Xen, 1) the first mismatch (in hpet_read(), length is 4) makes guest think the HPET DM is buggy (we return 0 for HPET_CFG.COUNTER_CLK_PERIOD to guest), so guest wouldn't use HPET at all. 2) the second one: if tmict is 62500000 and timer_divisor is 16 (Fedoar7's installer uses the values at some time), 10 * 62500000 * 16 = 0x2540BE400 -- it's too big to be held in uint32_t.
