4、？還是從零頁(yè)鏈表中分配的？哪一行語(yǔ)句減少了空閑頁(yè)的數(shù)量？哪一行語(yǔ)句將剛剛分配的物理頁(yè)由空閑狀態(tài)修改為忙狀態(tài)？答：本次分配的物理頁(yè)的數(shù)量是1，分配的物理頁(yè)的頁(yè)框號(hào)是0x409；物理頁(yè)是從空閑頁(yè)鏈表中分配的第226行MiFreePageListHead=MiGetPfnDatabaseEntry(Pfn)->Next;和第227行MiFreePageCount-;減少了空閑頁(yè)的數(shù)量，第229行將剛剛分配的物理頁(yè)由空閑狀態(tài)修改為忙狀態(tài)；（4）按F10單步調(diào)試MiFreePages函數(shù)的執(zhí)行過(guò)程，嘗試回答下面的問(wèn)題：本次釋放的物理頁(yè)的數(shù)量是多少？釋放的物理頁(yè)的頁(yè)框號(hào)是多少？釋放的物理頁(yè)是之前分配

5、的物理頁(yè)嗎？釋放的物理頁(yè)是被放入了空閑頁(yè)鏈表中？還是零頁(yè)鏈表中？繪制MiFreePages函數(shù)的流程圖。答：本次釋放的物理頁(yè)的數(shù)量是1，釋放的物理頁(yè)的頁(yè)框號(hào)0x409，釋放的物理頁(yè)是之前分配的物理頁(yè)；釋放的物理頁(yè)被放入了空閑頁(yè)鏈表中；見(jiàn)實(shí)驗(yàn)過(guò)程開頭流程圖部分。（5）按F10單步調(diào)試MmAllocateVirtualMemory函數(shù)的執(zhí)行過(guò)程，嘗試回答下面的問(wèn)題：分配的虛擬頁(yè)的起始地址是多少？分配的虛擬頁(yè)的數(shù)量是多少？它們和參數(shù)BaseAddress和RegionSize初始化的值有什么樣的關(guān)系？分配虛擬頁(yè)的同時(shí)有為虛擬頁(yè)映射實(shí)際的物理頁(yè)嗎？這是由哪個(gè)參數(shù)決定的？分配的虛擬頁(yè)是在系統(tǒng)地址空間（高

6、2G）還是在用戶地址空間（低2G）？這是由哪個(gè)參數(shù)決定的？參考MiReserveAddressRegion函數(shù)的定義和注釋，說(shuō)明該函數(shù)的功能。答：分配的虛擬頁(yè)的起始地址是0xa0003000，分配的虛擬頁(yè)的數(shù)量是1，BaseAddress和RegionSize初始化的值是期望保留或者提交的地址區(qū)域的起始地址和大小；分配虛擬頁(yè)的同時(shí)有為虛擬頁(yè)映射實(shí)際的物理頁(yè)，這是由第三個(gè)參數(shù)AllocationType決定的；分配的虛擬頁(yè)是在系統(tǒng)地址空間（高2G），這是由第四個(gè)參數(shù)SystemVirtual決定的；MiReserveAddressRegion函數(shù)的功能是保留一段虛擬地址區(qū)域。（6）按F10單步調(diào)

7、試MmFreeVirtualMemory函數(shù)的執(zhí)行過(guò)程，嘗試回答下面的問(wèn)題：本次釋放的虛擬地址是多少？釋放的虛擬頁(yè)是之前分配的虛擬頁(yè)嗎？參考MiFindReservedAddressRegion函數(shù)、MiFreeAddressRegion函數(shù)和MiDecommitPages函數(shù)的定義和注釋，說(shuō)明這些函數(shù)的功能。答：本次釋放的虛擬地址是0xa0003000，是之前分配的虛擬頁(yè)；MiFindReservedAddressRegion函數(shù)用于查找已保留地址區(qū)域，如果目標(biāo)區(qū)域非已保留區(qū)域則返回失敗，MiFreeAddressRegion函數(shù)用于釋放已保留地址區(qū)域和MiDecommitPages函數(shù)用于

8、釋放映射在連續(xù)虛擬頁(yè)框上的物理頁(yè)框。（7）在本實(shí)驗(yàn)3.3中，如果分配了物理頁(yè)后，沒(méi)有回收，會(huì)對(duì)EOS操作系統(tǒng)造成什么樣的影響？目前EOS操作系統(tǒng)內(nèi)核函數(shù)MiAllocateAnyPages能處理所有物理頁(yè)被分配完畢的情況嗎？例如在沒(méi)有可分配的物理頁(yè)的情況下調(diào)用該內(nèi)核函數(shù)，是否會(huì)返回失??？如果內(nèi)核函數(shù)MiAllocateAnyPages還不能處理這種極端情況，嘗試修改代碼解決這個(gè)問(wèn)題。答：如果分配了物理頁(yè)后，沒(méi)有回收，將會(huì)使可分配自由頁(yè)和零頁(yè)越來(lái)越少，最終導(dǎo)致內(nèi)存溢出，系統(tǒng)無(wú)法運(yùn)行。目前EOS操作系統(tǒng)內(nèi)核函數(shù)MiAllocateAnyPages不能處理所有物理頁(yè)被分配完畢的情況，在沒(méi)有可分配的物

9、理頁(yè)的情況下，不會(huì)分配物理頁(yè)，但仍然會(huì)返回成功，添加以下代碼即可：Elsereturn STATUS_MEMORY_NOT_ALLOCATED；（8） 在本實(shí)驗(yàn) 3.3 中，在分配物理頁(yè)時(shí)是調(diào)用的內(nèi)核函數(shù) MiAllocateAnyPages，該函數(shù)會(huì)優(yōu)先分配空閑頁(yè)，嘗試修改代碼，調(diào)用內(nèi)核函數(shù)MiAllocateZeroedPages優(yōu)先分配零頁(yè)，并調(diào)試分配零頁(yè)的情況。嘗試從性能的角 7 度分析內(nèi)核函數(shù) MiAllocateAnyPages 和 MiAllocateZeroedPages。嘗試從安全性的角

10、度分析分配零頁(yè)的必要性。 答：將MiAllocateAnyPages(1, PfnArray);修改為MiAllocateZeroedPages(1, PfnArray);即可。系統(tǒng)啟動(dòng)時(shí)，所有空閑物理頁(yè)都是未初始化的，此時(shí)零頁(yè)鏈表為空，MiAllocateAnyPages函數(shù)可以直接從自由頁(yè)鏈表分配，而MiAllocateZeroedPages函數(shù)會(huì)對(duì)從自由頁(yè)鏈表中分配的每一頁(yè)進(jìn)行零初始化，確保所有分配頁(yè)都是被零初始化的，再進(jìn)行分配，因此MiAllocateZeroedPages函數(shù)效率較低。但因?yàn)镸iAllocateZeroedPages函數(shù)對(duì)自由頁(yè)進(jìn)行了初始
