3、aseAddress和RegionSize個變量前后變化截圖界面。截圖見3.5。在實驗指導的P160-1.和2. 按F10單步調試MmFreeVirtualMemory函數(shù)的執(zhí)行過程，要求給出監(jiān)視窗口BaseAddress和RegionSize個變量前后變化截圖界面。 截圖見3.5。（2）按照實驗指導的P160-3.6 在應用程序進程中分配虛擬頁和釋放虛擬頁，編寫代碼。要求至少給出源代碼及其解釋。程序見3.6.2。 （3）按F10單步調試MiAllocateAnyPages函數(shù)的執(zhí)行過程，嘗試回答下面的問題：本次分配的物理頁的數(shù)量是多少？分配的物理頁的頁框號是多少？物理頁是從空閑頁鏈表中分配的

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

5、的物理頁嗎？釋放的物理頁是被放入了空閑頁鏈表中？還是零頁鏈表中？繪制MiFreePages函數(shù)的流程圖。答：本次釋放的物理頁的數(shù)量是1，釋放的物理頁的頁框號0x409，釋放的物理頁是之前分配的物理頁；釋放的物理頁被放入了空閑頁鏈表中；見實驗過程開頭流程圖部分。（5）按F10單步調試MmAllocateVirtualMemory函數(shù)的執(zhí)行過程，嘗試回答下面的問題：分配的虛擬頁的起始地址是多少？分配的虛擬頁的數(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系？分配虛擬頁的同時有為虛擬頁映射實際的物理頁嗎？這是由哪個參數(shù)決定的？分配的虛擬頁是在系統(tǒng)地址空間（高

6、2G）還是在用戶地址空間（低2G）？這是由哪個參數(shù)決定的？參考MiReserveAddressRegion函數(shù)的定義和注釋，說明該函數(shù)的功能。答：分配的虛擬頁的起始地址是0xa0003000，分配的虛擬頁的數(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；分配虛擬頁的同時有為虛擬頁映射實際的物理頁，這是由第三個參數(shù)AllocationType決定的；分配的虛擬頁是在系統(tǒng)地址空間（高2G），這是由第四個參數(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

7、試MmFreeVirtualMemory函數(shù)的執(zhí)行過程，嘗試回答下面的問題：本次釋放的虛擬地址是多少？釋放的虛擬頁是之前分配的虛擬頁嗎？參考MiFindReservedAddressRegion函數(shù)、MiFreeAddressRegion函數(shù)和MiDecommitPages函數(shù)的定義和注釋，說明這些函數(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；MiFindReservedAddressRegion函數(shù)用于查找已保留地址區(qū)域，如果目標區(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)虛擬頁框上的物理頁框。（7）在本實驗3.3中，如果分配了物理頁后，沒有回收，會對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能處理所有物理頁被分配完畢的情況嗎？例如在沒有可分配的物理頁的情況下調用該內(nèi)核函數(shù)，是否會返回失??？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問題。答：如果分配了物理頁后，沒有回收，將會使可分配自由頁和零頁越來越少，最終導致內(nèi)存溢出，系統(tǒng)無法運行。目前EOS操作系統(tǒng)內(nèi)核函數(shù)MiAllocateAnyPages不能處理所有物理頁被分配完畢的情況，在沒有可分配的物

9、理頁的情況下，不會分配物理頁，但仍然會返回成功，添加以下代碼即可：Elsereturn STATUS_MEMORY_NOT_ALLOCATED；（8） 在本實驗 3.3 中，在分配物理頁時是調用的內(nèi)核函數(shù) MiAllocateAnyPages，該函數(shù)會優(yōu)先分配空閑頁，嘗試修改代碼，調用內(nèi)核函數(shù)MiAllocateZeroedPages優(yōu)先分配零頁，并調試分配零頁的情況。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、度分析分配零頁的必要性。 答：將MiAllocateAnyPages(1, PfnArray);修改為MiAllocateZeroedPages(1, PfnArray);即可。系統(tǒng)啟動時，所有空閑物理頁都是未初始化的，此時零頁鏈表為空，MiAllocateAnyPages函數(shù)可以直接從自由頁鏈表分配，而MiAllocateZeroedPages函數(shù)會對從自由頁鏈表中分配的每一頁進行零初始化，確保所有分配頁都是被零初始化的，再進行分配，因此MiAllocateZeroedPages函數(shù)效率較低。但因為MiAllocateZeroedPages函數(shù)對自由頁進行了初始

11、化，減小了出錯的可能性，從而安全性較高。3.主要數(shù)據(jù)結構、實現(xiàn)代碼及其說明typedef struct _MMPFN     ULONG Unused : 9;   / 未用   ULONG PageState : 3;  / 物理頁的狀態(tài)   ULONG Next : 20;   / 下
