python 2.7 編譯

 1: download python 2.7.18

   https://www.python.org/ftp/python/2.7.18/Python-2.7.18.tgz

   

2: change deb-src

   software & Updates 裡面改source code到Taiwan

   

3: apt-get build-dep python3

4: sudo apt-get install \

curl \

gcc \

libbz2-dev \

libev-dev \

libffi-dev \

libgdbm-dev \

liblzma-dev \

libncurses-dev \

libreadline-dev \

libsqlite3-dev \

libssl-dev \

make \

tk-dev \

wget \

zlib1g-dev

5:: apt-get install zlib1g-dev libdb-dev libncurses5-dev libncursesw5-dev libsqlite3-dev libssl-dev

6: ./configure

7: make -j`nproc`

8: make install

9: wget https://bootstrap.pypa.io/pip/2.7/get-pip.py

10: python get-pip.py

stable-diffusion-webui-master torch==2.4.0

 stable-diffusion-webui-master\modules\launch_utils.py

torch_command = os.environ.get('TORCH_COMMAND', f"pip install torch==2.4.0 torchvision==0.19.0 --extra-index-url {torch_index_url}")

可以改版本安裝

tpm2-tss debug

netif_dbg 有的會印, 有的不會印

 netif_dbg

netif_dbg(pdata, drv, pdata->netdev, "???!!!\n");  不會印

netif_dbg(pdata, link, pdata->netdev, "CL73 AN initialized hahaha ~~~\n");  會印

#define netif_dbg(priv, type, netdev, format, args...) \

do { \

if (netif_msg_##type(priv)) \

dynamic_netdev_dbg(netdev, format, ##args); \

} while (0)

#define netif_msg_drv(p) ((p)->msg_enable & NETIF_MSG_DRV)

#define netif_msg_probe(p) ((p)->msg_enable & NETIF_MSG_PROBE)

#define netif_msg_link(p) ((p)->msg_enable & NETIF_MSG_LINK)

可以看的出來是priv的變數中決定哪一些要印的.

請以NETIF_MSG_LINK之類作為關鍵字搜尋, 把自己想印的加進去

enum {

NETIF_MSG_DRV = 0x0001,

NETIF_MSG_PROBE = 0x0002,

NETIF_MSG_LINK = 0x0004,

NETIF_MSG_TIMER = 0x0008,

NETIF_MSG_IFDOWN = 0x0010,

NETIF_MSG_IFUP = 0x0020,

NETIF_MSG_RX_ERR = 0x0040,

NETIF_MSG_TX_ERR = 0x0080,

NETIF_MSG_TX_QUEUED = 0x0100,

NETIF_MSG_INTR = 0x0200,

NETIF_MSG_TX_DONE = 0x0400,

NETIF_MSG_RX_STATUS = 0x0800,

NETIF_MSG_PKTDATA = 0x1000,

NETIF_MSG_HW = 0x2000,

NETIF_MSG_WOL = 0x4000,

};
