Linux核心路徑和壓縮

我正在嘗試查找 Linux 核心路徑，以找出它在工業 Raspberry Pi 中使用的壓縮類型。

我正在執行命令cat /proc/cmdline並獲取輸出：

dwc_otg.lpm_enable=0 smsc95xx.macaddr=18:83:C4:04:49:C5 root=/dev/mmcblk0p2 rootfstype=ext4 rootwait noinitrd elevator=deadline bcm2708_fb.fbwidth=1920 bcm2708_fb.fbheight=1080

的內容/boot是（Linux核心鏡像應該在這裡）：

但我看不出它們之間的關係……有人可以幫我辨識圖像並解釋命令的輸出cat /proc/cmdline嗎？

更新

在我的帶有 Arch Linux 的筆記型電腦中，這種關係很清楚：

輸入：cat/proc/cmdline

輸出：BOOT_IMAGE=/vmlinuz-linux root=UUID=[...] rw quiet

在/boot我可以找到：

-rw-r--r-- 1 root root 6289792 oct 18 02:15 vmlinuz-linux

您正在查找zImage列表底部呼叫的文件。

如果我沒記錯的話，那是gzip引導載入程序載入的壓縮核心映像。

我在快速搜尋中找到的最佳參考是https://en.wikipedia.org/wiki/Vmlinux。

如果有人有更好的參考，請隨時編輯或評論。
