上面的代码给出了pte对应的页没有驻留在主存中的情况。如果pte对应的页没有驻留在主存中,且没有映射任何页,即pte_present()返回0,pte_none()返回0,则要判断要分配一个匿名页还是一个映射页。在Linux虚拟内存中,如果页对应的vma映射的是文件,则称为映射页,如果不是映射的文件,则称为匿名页。两者最大的区别体...

None of these compounds inhibits BRD4 at submicromolar concentration except the compounds substituted with an amino or a methylsulfonyl group on the terminal phenyl ring. Compound 7.2.1.156 is identified as the most potent BRD4 inhibitor from the series (IC50 79 nM). It binds with BRD4 through ...
PTE_PRESENT:其实一个虚拟页面有没有在内存中有两种情况,一种是页面压根就没被分配,另一种是被换出了,如果页面是被换出的,那么 PTE_YOUNG 会被置位,而 PTE_PRESENT 会被清除,如果是压根没有分配,两个标志位都为 0。 对于一个装有二级页表 block 的 page,它的布局为: ...
In the present study we found a significant decrease of the three isopters’ area during follow-up. Moreover, relationship was found between I2e isopters’ area and both the cumulative dose and the mean daily dose of VGB. Cumulative VGB dose has been already found the most significant pre...
